awsome little tool great alternative for making thumbnails for websites.

Unknown author (2005-10-26 00:00:00):

fine tool - extremely simple to use :-)

Unknown author (2005-10-28 00:00:00):

This little software is a giant. I wish all software were as small, simple and effective as this one. I reduced an album of 90 jpegs from 81MB to just under 4 MB using 800 pixels, thus saving space on my webspace.
A very big thank you to the maker.

Unknown author (2005-10-30 00:00:00):

Simple and quick to use, ideal for making thumbnails.

Unknown author (2005-11-02 00:00:00):

I would love to see this resize via DPI too. My resizing needs are for printing. Say something like: PhotoResizeD300.exe would resize the picture by changing the pixel density to 300.

jleslie48 (2005-11-07 00:00:00):

what a product. so nice to see a KISS (keep it simple) program that is so usefull and pinpoint accurate to what it should be doing. I like the "rename the program name" parameter list, being an old command line programmer I know exactly where this comes from, although having command line parameters would be more flexible,
(eg, "$photoresize -p400 -r -c -dc:\picturedirectory")

but hardly really worth changing just for that. The only reason I bring it up is a request for one additional feature, rather than just a fixed target size, I'd like to see a percentage target size, like say 50%. The reason I bring this up is because my application was for conversion of jpgs that were scale drawings, all of which were scaled the same, but unfortunately the size of each image (widthxlength) were different. Using this program worked great to reduce all the images to a constant size, but as a result all the blueprints were no longer in scale with each other. I had to increase the borders of all the images to the same as the largest jpg, before I could run this program to get it all correct. Just a wish list item.

The product is great. I'd like to make a cash donation, is this possible??

Vlasta (2005-11-07 00:00:00):

Answers to the technical questions and suggestions are in this forum thread.
Regarding the donations - it is currently not possible, because PayPal does not offer full services in our country. Anyway, the tool was not really made for profit, but because some friends of mine needed a simple solution.

jleslie48 (2005-11-09 00:00:00):

I can see its not about profit. that's why I want to donate. I wouldn't of paid for the program. I want to offer my REAL appreciation. That is as honest and true a thank you as I can think of.

Unknown author (2005-11-16 00:00:00):

Is it limited to 18 pics at one time?

Vlasta (2005-11-17 00:00:00):

The number of images processed in one step is limited by a command line length as discussed here.

Unknown author (2005-11-17 00:00:00):

ahahaah!!!! GREAT!!!


Unknown author (2005-11-23 00:00:00):

Th pictures are really small, sometimes, toooooooooo small

Unknown author (2005-11-29 00:00:00):

Wow what a fantastic application! Exactly what I was looking for, thanks very much.

I'm not sure how complicated it would be but support for GIF and/or BMP files would be a great expansion, though that could complicate things unnecessarily.

Vlasta (2005-11-29 00:00:00):

Support for other image formats would increase the size of the application and make it more complicated. But another tool can be created... let me know.

Unknown author (2005-11-30 00:00:00):

VERSION 1.3 ROCKS!!! Thank you SO much for the density setting!!!

Unknown author (2005-12-07 00:00:00):

Too good to be true

Unknown author (2005-12-07 00:00:00):

Troppo forte!

Unknown author (2005-12-11 00:00:00):

is this thigy free

Unknown author (2005-12-11 00:00:00):

More than perfect!

Unknown author (2005-12-17 00:00:00):

Abso-blinkin-lootly-fantastic. You've just saved me from manually resizeing 266 files. You are gods. I love you...

Unknown author (2005-12-23 00:00:00):

thank you. nice application :-)

Unknown author (2005-12-25 00:00:00):

Giles: fundamental flaw, the metadata is not preserved

Vlasta (2005-12-26 00:00:00):

That is true, the resized image is created from scratch. I'll try to fix it in the next release.

Unknown author (2005-12-28 00:00:00):

very simple and nice, thanks.

Unknown author (2006-01-04 00:00:00):

Great for what it does.
Would be more useful it we could specify resize to a specific width or to a specific height allowing the other size to be larger if needed.

Vlasta (2006-01-04 00:00:00):

That feature was added in version 1.1 - check the W, H, and _ options.

Unknown author (2006-01-06 00:00:00):

I love the application, but have one issue. Is there an upper limit to the size of an image that can be resized? I have a 27 MB jpeg and the program reports an error when trying to resize it.

Vlasta (2006-01-07 00:00:00):

There are multiple indirect limits, one of them is for example size of available memory, but there are also others. Could you make your jpeg available online or send me dimensions of that image. If it was something else than memory, I will try to fix it in the next release.

Unknown author (2006-01-07 00:00:00):

Please add shell integration for even faster use!

Unknown author (2006-01-10 00:00:00):

Excellent program! Glad it's free also. I use it at work to reduce the size of pictures taken by our digital camera (~500k) down to a size that makes it possible to include a bunch of pictures in a powerpoint file without it being like 10MB :-)

Unknown author (2006-01-16 00:00:00):

It's just what I need for my montages!

Unknown author (2006-01-16 00:00:00):

Great tool :-) Quick and efectve :-)

Unknown author (2006-01-18 00:00:00):

Great Tool! Simply and easy to use! Great for web development!

Unknown author (2006-01-19 00:00:00):

I had no idea how easy resizing jpeg's was. I was up and running in under 5 minutes using your tool. Thank you for making it so usable and effective.

Unknown author (2006-01-23 00:00:00):

I have to say, this is the coolest thing I have found. I just tried it on my photos that needed to be reduced. All I had to do way drag the whole file onto the tool!!! And it worked!!!! It was just too easy. Thanks so much!!!!

Unknown author (2006-01-24 00:00:00):

Thx for this great tool ! Is there any way to define the Quality of the JPEG format ? i.e. compression quality 85% or 70% ? Regis

Vlasta (2006-01-25 00:00:00):

No, that is currently not possible. It will be considered for the next version.

Unknown author (2006-01-26 00:00:00):

Amazing! No word can express my appriciation.
Did not find it from others' feedback: I don't want to close the DOS window, would like to have it closed by default, this is available in command line, is it or could it be available by changing the file name? Thanks!!!

Unknown author (2006-01-31 00:00:00):

Great tool, just what I was looking for for ebay pictures. Nice and simple .. couldnt be better.

Unknown author (2006-02-02 00:00:00):

Hello !! An other feature that can be added : can you plan to keep Exif infos in JPEG pictures ? i.e. I use a tool to auto-rotate-lossless my jpeg picture.. Jpeg generated with your tool does not have exif infos anymore so that the tool can not know the orginial info of the picture.. Exif should be a block of date header of footer in the picture don't know exactly and this should not be too tricky to implement.. Anyway, Great tool you've done !! Hope we could be able to choose jpeg quality in future version. Thanks again and keep up the good work. Regards, Regis.

Unknown author (2006-02-02 00:00:00):

sorry, in my previous message I meant : "Exif info should be a block of datas header or footer in the picture..." Bye. Regis

Vlasta (2006-02-02 00:00:00):

Thanks for suggestions. I guess there are enough of them for a new version...

Unknown author (2006-02-07 00:00:00):

Really Cool and easy application

Unknown author (2006-02-11 00:00:00):

this is wackkkkk

Unknown author (2006-02-13 00:00:00):

This has been a life saver for me, so easy to use! Thanks

Unknown author (2006-02-13 00:00:00):

Perfect tool, i just added some advertising on my page www.phpalbum.net

Unknown author (2006-02-16 00:00:00):

It works well, just as advertised. I would like to be able to specify the compression, though. Your standard compression is too lossy.

p.izard (2006-02-16 00:00:00):

With Photo Resize on command line, how to specifie an output directory ?

Vlasta (2006-02-17 00:00:00):

You cannot. Instead switch to that directory (using CD in batch file) and then use the "C" option to write images to current directory.

Unknown author (2006-02-21 00:00:00):

really good! but it would be even better if you could define the compression quality... the images really dont look good at this compression

Unknown author (2006-02-24 00:00:00):

Save me a lot of time - Thanks a lot -

Unknown author (2006-02-24 00:00:00):


Unknown author (2006-02-25 00:00:00):

Nice tool! Others already said it, being able to set the JPEG quality would make it a perfect tool.

Unknown author (2006-02-27 00:00:00):

Extremely nice, easy-to-use tool. One idea for the next version might be to allow the user to overwrite source files (or use original filenames if dest dir != src dir)

Unknown author (2006-02-28 00:00:00):

It's hard to make things simple. Many non-free tools are just too complex and you have to install them on your pc. This tool just does what I want it to do: resize!! I'm also very pleased with the quality/filesize aspect of the resized images.

Unknown author (2006-03-06 00:00:00):

Must say this is the best thing i've seen for photo's next to photoshop .. totally different things, but truely serve the purpose!

Unknown author (2006-03-11 00:00:00):

Absolutely brilliant. Just one thing though if you ever convert it to a GUI application I'll hunt you down and hurt you ;-). Always KISS Keep it Simple Stupid.

Unknown author (2006-03-22 00:00:00):

The world is full of amazing people doing amazing things. This tool is deceptively simple - its simplicity hides its genius.

g00ner_1 (2006-03-22 00:00:00):

Ingenious - what a superb little app, thank you so much. My life has become so much easier.

Unknown author (2006-03-26 00:00:00):

Great tool. Our office has images that need to be resized for posting to websites and this makes it so easy that even the boss can do it. Thanks for providing such a neat tool. Found it by searching Google. CN in Tennessee, USA.

Unknown author (2006-04-09 00:00:00):

Great tool, very helpful for me since I'm travelling and need to resize to different formats for my website. Missing one feature, though... the possibility to decide the output filename. Thanks for a great tool./Andreas

Unknown author (2006-04-13 00:00:00):

Splendid tool! Now I don't have to abuse Outlook (with powertool extension) anymore to produce smaller pictures in a simple way.

P.S. Can you make a similar tool for compressing wav to mp3 (i.e AudioResize192.exe)?

Unknown author (2006-04-26 00:00:00):

The DPI setting is great, but I would like to see an option to NOT resample the image. Currently if I have a 2000x2000/72DPI image and I use the tool to change the DPI to 300 I get an image with a DPI setting of 8333x8333. A switch that would override resampling and create an output of 2000x2000/300dpi would help make my job SO much easier. Thanks for a great tool. Keep up the good work.

Vlasta (2006-04-26 00:00:00):

:-) you are not the first one, who needs this feature. I am somewhat reluctant to add this mode, because then the application task is reduced to just overwritting a number in JPG header. And it should not recode the image to preserve the quality. Well, since this is a repeated request, I'll try to add this feature in the next version.

Unknown author (2006-04-29 00:00:00):

Really liked it !!! it also support hebrew folder names. Great !

Unknown author (2006-05-01 00:00:00):

The tool is wonderful. Reading previous comments, I see that I am hardly the only one to think so. I really appreciate minimalistic tools, and I use this one (along with the Send To tip) to help my mom convert her digital images to smaller sizes for her website.

My feature request is to enable the usage of units other than pixels (centimeters, millimeters, and maybe inches for the folks in the USA). It would mean adding a DPI-aware calculation routine inside the program, but would eliminate the need for a manual calculation beforehand. Which means my mom can remain blissfully ignorant :-)

Thanks again!
Neer from Israel

Vlasta (2006-05-01 00:00:00):

OK, that should not be a problem. I'll keep that in mind.

Unknown author (2006-05-05 00:00:00):

hi, this is a wonderful display of how programming somthing simple should be, i was wondering if i can i hop over pressing enter at the end each time, could the program just close itself automatically...

alon (2006-05-09 00:00:00):

I truly join all the praises above me!! Really great tool!!
However - I tried to run it with the following arguments:
PhotoResize.exe -w400 -r -c "-o<SRCPATH> -> <DSTPATH><EN>" "C:\Documents and Settings\Administrator\Desktop\a1" > pics.txt
where 'a1' hold this batch file, 'PhotoResize.exe' and a folder AA which hold pictures and another folder BB which also hold pictures.
In the output 'pics.txt' I found only src and dst file names NOT full path (i.e "a.jpg -> a-W400.jpg"). When trying with opcode SRCNAME and DSTNAME - I got this: ".jpg -> -W400.jpg"

Thanks a lot.

Vlasta (2006-05-10 00:00:00):

Ouch, you have found a bug. The -c flag seems to have a disruptive effect on path variables. I guess I'll add a switch to set the output directory explicitly.

alon (2006-05-10 00:00:00):

Hi Vlasta,
Adding this switch will be great. Can you preserve/fix the <SRCPATH> so a full path source will be available?
A switch for files renaming conversion is also a great feature that will be welcomed... :-)

Vlasta (2006-05-10 00:00:00):

Yes, that will be fixed too. I am not sure about the file renaming, is there a useful scenario requiring that feature and is there a robust way how to specify the output names (I mean without potential conflicts)?

alon (2006-05-11 00:00:00):

Currently you automatically add "-W400" to the original name - that convention is not always good - especially when using your tool for publishing images on the web and wanting to preserve the original name OR rename all pictures for certain cause... about treating a conflict - if XXX.jpg already exists - you can recursively name the new file XXX(1).jpg (I recommend recursion so if XXX(1).jpg also exist - you'll name the new file XXX(1)(1).jpg).

Vlasta (2006-05-12 00:00:00):

There already is an option to overwrite the original images (I). If this option is not used (the default case), there is a need to differentiate the resized name from the original. The current method appends a suffix that carries an information and I do not see any advantage in dropping that and using just numbers. If there is something I am missing please let me know.

alon (2006-05-12 00:00:00):

I want to keep the original picture (name and size) but I do understands your meanning. So maybe you can let the user change the name (or keep original...) only when using different destination folder than where the original images are.
BTW, what is the 'L' switch stands for?

Vlasta (2006-05-14 00:00:00):

Yes, that sounds good. I was actually mentioning the i(I) switch (in-place resizing). 'L' is used as a part of filename only and it means Low quality (the same as -q30).

Unknown author (2006-05-16 00:00:00):


It would be really good if you could resize images into a different folder, but keep the file name the same so ../pics/image.jpg would become: ../pics/tn/image.jpg rather than ../pics/tn/image200.jpg


Unknown author (2006-05-30 00:00:00):

I love this resizer! I volunteer at an animal shelter and usually have 20-35 pictures of animals to upload to my website each week. This program makes it so easy to rename the file and have the exact size I need for the website (360kb) and resize them all at once.

Unknown author (2006-06-07 00:00:00):

I am a little confused regarding the resizing and the DPI. I have an image that is 205dpi and of size 2050x1540. I'd like to resize to 410x308 and maintain as much quality as possible.
I use the -q100 setting, and the -w410 setting, but this results in an image with 41dpi. Adding -d96 creates an image of 96dpi, but that is 960x721. What am I missing?

Myrmex (2006-06-14 00:00:00):

Hello, Congratulations for a such usefull tool.
What about adding a conditional statement regarding the minimum size of pictures resized ? I mean something saying "please do not deal with small size pictures" - this would prevent the tool to redraw again and again files when ran from day to day.

Vlasta (2006-06-14 00:00:00):

I see, you always run the tool on a folder with all your old and new images. Interesting use case, we'll try to have it covered in the next version.

Myrmex (2006-06-15 00:00:00):

A good news :o)
Yes, you're right: I plan to use it on a fileserver with a script running e.g. every week - my goal is to decrease amount of data on the server - this could also decrease backup time frame.
The app's arguments "-o -r -m -i" will be my friends ;-)

I will wait for your next version - thank's again for your great job.
Could you please confirm I can use your software in a business environment (I mean on my corporate fileserver) ?

Vlasta (2006-06-15 00:00:00):

There's no problem using it on your fileserver. One more thing: I would not recommend to use the tool in the current state. If an image is decoded and the encoded again, there may be a slight quality loss. I hope the next version will be out in July, so it may be better to run it just once now and wait for the update.

Unknown author (2006-06-16 00:00:00):


jtroll (2006-06-21 00:00:00):

I seem to be unable to dump more than 20 photos at a time on to the icon. Am I doing something wrong?

jtroll (2006-06-21 00:00:00):

I found the answer in your comments section regarding maximum number of photos resized in one dump. I will try your recommendation!

Unknown author (2006-06-27 00:00:00):

This tool is exactly what I was looking for. Thanks so much!

Unknown author (2006-06-29 00:00:00):

Thank you for saving a lot of time with my individual down loads and my batch down loads. This is one cool tool.

Unknown author (2006-06-30 00:00:00):

great piece of software, exactly what I was looking for :-)

Unknown author (2006-07-02 00:00:00):

Great product but maybe one suggestion i was wonering if you could have a .txt document with all of the commands inside them so i dont have to connect to the internet to modify the conditions.

Vlasta (2006-07-03 00:00:00):

If you need to access the instructions offline, just save this page or the page with advanced settings. All major browsers can do that. ;-)

Unknown author (2006-07-06 00:00:00):

oh my god this app is the greatest. thank you!

Unknown author (2006-07-11 00:00:00):

AWESOME!!!!!!!!! It's so simple.... yet so gooooood.

Unknown author (2006-07-17 00:00:00):

Perfect.Perfect application also because it does not need installation. Great work!

Unknown author (2006-07-20 00:00:00):

Your application is really brilliant!

However, an interesting function would be to be able to resize ONLY the images which exceed a certain dimension (in width or height).

For example:
In a directory, I have 2 images. One dimensions of 3000x1900, the other of 1600x1200. Let us imagine that I want that my images do not exceed 2000px as well in width in height. The ideal would be that a function makes it possible the application to check if the image exceeds or not 2000px, if so, it resize the image like it does it already, if not it resize not.

I hope that I was rather clearly in my explanations.
And sorry for my bad english (I am french ;-) )

Unknown author (2006-07-23 00:00:00):

Hello Vlasta ! Thanks for adding new features we asked you ;-) An other option would be nice : since resizing pictures often slighty blur the smaller pictures we get, what about adding a switch so as to choose a SHARPENING function ? 2 levels of sharpening should be enough like : "Sharpen" and "Sharpen more". Thanks again for this very handy tool. Kind regards, Regis.

Unknown author (2006-07-26 00:00:00):

Wow, very useful program!!! can set the width,height,WxH,percentage,DPI...etc, a small but good software, thanks to the author.

Eriks S (2006-07-28 00:00:00):


I am very satisfied with your programm and want to use it in commercial project. Can I use it for free in commercial environment? I am not planning to sell it, I am simply planning to install it to computers of my customers.

Thanks, in advance!

Vlasta (2006-07-28 00:00:00):

Yes, you may use it in that scenario.

Unknown author (2006-08-06 00:00:00):

Wow. Why didn't somebody program this ten years ago? Brilliant. Huge props, this is exactly what I need for my travelogue. Perfect for USB keys.

Unknown author (2006-08-06 00:00:00):

perfect, just what I was looking for

Unknown author (2006-08-10 00:00:00):

What is the maximum numbers of files I can do at one time? I tried to do 72 pictures at once and it gave me an error. I did it in a few smaller batches and it worked fine.

Vlasta (2006-08-11 00:00:00):

The number of images processed in one step is limited by a command line length as discussed in this thread. You may drop an entire folder (or more) on the icon to process all images inside.

Unknown author (2006-08-14 00:00:00):

Brilliant, smooth and stable with good results, ive linked to it on my site :-)

Unknown author (2006-08-16 00:00:00):

This is amazing, things that work simply and quickly with no training for non graphics people are truly beautiful solutions!

Unknown author (2006-08-17 00:00:00):

i'm a VB programmer and i was wondering if i could destribute this software along side of my software as long as i talk about your site in the about form of my software. Please comment.

Vlasta (2006-08-17 00:00:00):

That would depend on the nature of your application, we'd better discuss this by email.

Unknown author (2006-08-17 00:00:00):

What a wonderful app! You have done a great job here. Thanks.

Jeremy (2006-08-18 00:00:00):

You have such an outstanding and flexible program. I have never found a program that is flexible and advanced enough to do what I want, yet be easy enough for a non-technical relative to use, too! I wish all developers put as much thought and effort into their programs. Kudos!

Unknown author (2006-08-21 00:00:00):

I love this program, especially it can copy the EXIF into the resized picture. But when I use "I" & "S" together, it deleted all the original files with size smaller than the required sized. I am looking forward to seeing if this can be fixed. This is the file name I used "PhotoResize1600HMRIS.exe"

Vlasta (2006-08-22 00:00:00):

Thanks for letting me know, this is surely an unexpected interference between the "I" & "S", I hope to have it fixed this week.

Unknown author (2006-08-23 00:00:00):

Awesome utility - nice and simple! Keep up the great work!

Unknown author (2006-08-24 00:00:00):

Very nice utility! Convenient usage system.
Suggestion: For making images anamorph (e.g. for use if you want to create widescreen movies with Photo Story 3), could you implement WxH syntax for the P option? Example: PhotoResizeP100x133.exe -> 100% width, 133% height. /Lars J

Vlasta (2006-08-27 00:00:00):

The "I" + "S" bug and a another one related to resizing to given filesize were fixed. Version number was not updated - download the 1.5 again if you want the version without these errors.

Unknown author (2006-08-29 00:00:00):

wow, nice nice program. This has so many applications it is amazing.

Unknown author (2006-08-30 00:00:00):

I think I have found the tool i need!!!!!!!!!!! thks a lot!!!

suggestion: could we choose the destination file name?? like folder.jpg (from front.jpg) it will be the best!!

polossatik (2006-09-05 00:00:00):

Just an idea: exif data contains in a lot of cases the position of the camera, a option to rotate automatically based in that?

"If you want to manually control both width and height of the output image, rename the application to PhotoResizeWxH.exe, where W is the requested width and H the requested height. It is your responsibility to set correct aspect ratio in this case."

This tool is AWESOME, but if there's a way to maintain the aspect ratio while doing 800x600 that would be great. Because if you do any standard sizing, the picture will be a little bit out of propotion.

Vlasta (2006-09-07 00:00:00):

Thanks for the recent suggestions, they will be taken care of in the next update.

wildsun (2006-09-08 00:00:00):

We can not open the photoresize after the download on my computer. Can anybody help me?

Vlasta (2006-09-08 00:00:00):

First, make sure, you downloaded the right version for your operating system. The file also might have been corrupted during transfer - downloading it again may help.

Unknown author (2006-09-09 00:00:00):

This is EXACTLY what I've been looking for for umm.. fifteen months now. Great work.
Two possible suggestions; be able to specify a folder for the pictures to be created in e.g. PhotoResizeWxH Fnewphotos.exe or something.
Automatic update or information of an update becoming available when you launch the program.

one of ythe best resizers available - thanks

Unknown author (2006-09-22 00:00:00):

This is a nice piece of software, but one thing prevents me (and possibly many others) for using it in a certain way. I want to use this on a website with classic ASP to resize pictures automatically without buying an expensive component (that does more than I need anyways). HOWEVER, I can't use this because when run from the command line you have a "Press enter to exit" at the end. Command line programs should just exit and not require user intervention. So when I put this on my webserver, it hangs that page indefinitely. Please remove that, or add an option to exit automatically when done. I would be happy to provide an ASP snippet to show how it can easily be implemented into a website. THANKS!

Vlasta (2006-09-22 00:00:00):

There already is a parameter that lets you skip the Press Enter message: -o (It also lets you customize the output of the tool - check the advanced settings page.) An ASP snippet would of course be welcome. If it is short, you can post it here as a comment, otherwise please send it to our email and it will be put on a separate page, with your name as an author of course.

Unknown author (2006-09-24 00:00:00):

Thanks for the info. I didn't see the advanced settings in the documentation that came in the ZIP. Anyways, here is how you can add the code into an ASP document:

Set objShell = Server.CreateObject("WScript.Shell")
strCommand = Server.MapPath("PhotoResize200H.exe -o") & " " & Server.MapPath(fullpath)

objShell.Run strCommand, 0, True

Set objShell=Nothing

fullpath of course needs to have your filename in it. So basically, when someone uploads a file this version would resize a thumbnail to 200 pixels and keep the quality high. I used another command in succession to create an image 750 pixels wide. In my case, this was perfect!

stennie (2006-09-27 00:00:00):

Very helpful utility! One feature suggestion .. would be nice if there was an option to include the original picture resolution, file name, file size, and file date as Exif comments (eg Original Resolution : 1200 x 1800, Original Filename: foo.jpg, Original Filesize : 1389711 bytes, Original file date: 2006:09:26 06:59:00 ). Details of the original would be helpful when using the resized versions to catalog much larger photos. Thx !

Unknown author (2006-10-06 00:00:00):

Outstanding work! This is a great little utility that lets me enjoy on Win 2000 the same features I've gotten used to on WinXP! XP has the "Image Resizer" Powertoy, but 2K is lacking that. With your program and a few modified shortcuts, I was able to add in some slick "send to" menu items that let me do the exact same thing. Thanks!

A quick question: I'm trying to resize images and keep the same aspect ratio no matter if they are rotated landscape or portrait. For example: I'd like to resize all images to 640 x 480. A few are rotated so I'd like those to be resized to 480 x 640. Is there a simple way to do that in the command line switches?

I've tried -^640x640 to bound either dimension to 640 max, but the output is a square 640x640 image.

I also tried -w640 -s -h640 hoping that it would

 1) first resize the pic with a width of 640 (and height of 480),
 2) then skip files with a height less than 640


Vlasta (2006-10-06 00:00:00):

If I undertand you correctly, you are looking for a command line switch that reverts back to the default behavior - that would be -^640

Unknown author (2006-10-07 00:00:00):

Is there a way to keep the original size of the photos but reduce the quality? I want to keep the HxW of the pics the same but need to reduce the size on disk to around 100-200k max

Vlasta (2006-10-07 00:00:00):

Then you could try to resize to 100% (PhotoResizeP100.exe) and play aroud with the quality setting. Lower quality often means smaller size.

Unknown author (2006-10-15 00:00:00):

Hey, I like this software very much. And especially the copy function. But i would be happy if it could make a folder with the pictures at the destination when i select a folder to be resized, instead of just the files. I would also like to keep the filenames intact, with no addition, when copying the files. Also when skipping smaller pictures, it could be nice if it still copy the picture to the destination.

Unknown author (2006-10-22 00:00:00):

I was amazed at how simple this program made resizing! Thank you for creating something so easy to use and functional at the same time!

Unknown author (2006-10-27 00:00:00):

When I am trying to resize 6000 pictures in batch, I get this error: "Access to the specified device, path, or file is denied". Is there a maximum number of pictures that I could resize at one time? Thanks.

Vlasta (2006-10-27 00:00:00):

Number of images is limited by length of Windows command line. Instead of dragging and dropping the individual image, d'n'n the entire folder.

Unknown author (2006-10-29 00:00:00):


I am really, really, really happy with this tool! There is only one thing I am looking for: a tool that automatically adds a copyright stamp to the image (like in the left corner of the image)...?

Unknown author (2006-11-05 00:00:00):

Hi, great small tool, I like it.
I'm trying to resize and change DPI direct in one step without lose quality.How to do it?
One Example I have picture 300dpi W50xH70, and i want resize the picture
in 150dpi W200xH200, without lose quality.
Thanks in advance!

Unknown author (2006-11-05 00:00:00):

sorry the last comment was specified in millimeters (H and W)

Vlasta (2006-11-07 00:00:00):

If you want to change both size and DPI and the source and destination are not in relation, you'll have to do it in two steps. Just resize to target size in pixels and then overwrite the DPI with PhotoResizeD150T.exe. No quality will be lost in the second step.

Unknown author (2006-11-07 00:00:00):

I have many pictures, and they are all different, some of them are bigger in size but smaller in dpi, other have bigger dpi and small size, i want resize them all in same size and dpi, other problem that i have is that pictures have different aspect ratio, and i want maybe small changes in aspect ratio, the end result should be all pictures have same size / aspect ratio, and same dpi without quality lose!
Trying to do it in one step or in one bat file!

Is that possible with only this great tool?
Vlasta i know you already mention i should do it in two steps, this time i'm little more specific!

Before i found your site / PhotoResize i do it manual with Corel Photo Paint, open picture, right click, resample, with that method i become best results, but its take to much time for me to resample every single picture with this method!

I hope you understand me, because english is not my country language!

Vlasta (2006-11-08 00:00:00):

You'll need to run PhotoResize two times to get what you want (but it should be possible to do it from one .bat file). You need not worry about the quality, because if you only change DPI with the T letter in filename, the file is actually just copied without touching the compressed data and the DPI is overwritten.

If you want to change the aspect ratio, then just specify both width and height (for example PhotoResize400x300.exe).

You could also use the I (i) flag to overwrite the original files.

The .bat file might look like this (I did not try it myself, therefeore I cannot guarantee it's OK):
PhotoResizeD150TI.exe %1
PhotoResize400x300.exe %1

Unknown author (2006-11-08 00:00:00):

With this method i become picture with 150dpi (Hor. and Ver.) and 713x713 pixels in size.

Because with your method i become
Horizontal 205dpi and Vertical 145dpi and 713 x 713 pixels in size
Yours method change aspect ratio in dpi!
I become that what i want with this method but with quality lose after second step.

PhotoResize shortcut: PhotoResize.exe -o -q100 -^713x713 -t
with quality lose after second step!

other method:
PhotoResize713x713T with shortcut: PhotoResize713x713T.exe -o -q100
same quality lose after second step.

Do i miss somthing!

Best regards!

Vlasta (2006-11-08 00:00:00):

You are right, the T parameter should be used in the second step too (or you can swap the steps). I am not sure what you mean by lost quality, but resampling simply changes the picture and makes it different - the pixels change. If you are using it to prepare pictures for printing, then you'll probably would not want to change the number of pixels at all, just recalculating the DPI - but I am afraid this mode is not available in the current version.

Unknown author (2006-11-09 00:00:00):

Vlasta, i have used Photo Paint to see difference after resampling with my old method, and with PhotoResize.
You should try, to see about what I talking!
With PhotoResize i lose quality when i will become that what i need!
Im not sure can you make PhateResize to resample pictures like Photo Paint do, because with Photo Paint there is no quality lose, but i like yours PhotoResize.
Is there a possibility that i send you pictures to see difference that i talking about?

Best regards.

Vlasta (2006-11-09 00:00:00):

Yes, please send me the sample pictures and the configuration you have used Photo Paint, I'd like to know what's happening. If the photos are large, please send them directly to vlastimil.miler at gmail.com.

Hi... I LOVE your product... so easy and quick to use. One question, is there a size or number of files limit, as I only seem to be able to resize about 30-40 photos per time (6 MP photos, about 3Mb each). If you can solve this, I would be happy to donate!

Thanks, Keith

Taipan (2006-11-16 00:00:00):

Oops Taipan again... read the instructions (i.e. use a folder...)...it's working great now!!!

bigbangtech (2006-11-22 00:00:00):

I would like to suggest a feature for PhotoResize that may be useful to many users: making rectangular images square. Many people must put up 1000's of images on shopping websites, and sometimes the best format is square, but sometimes your images may be mixed with their longest side either being horizontal or vertical and it is a bit of a pain to process all of these images. An option that takes any rectangular-shaped image, horizontal or vertical and places it in the center of a XXX-sized square with blank/white bars on the top or sides where applicable would be most appreciated and most appropriate for PhotoResize!

birs (2006-11-26 00:00:00):

I have many pictures in standard formats 2:3. Some are landscape, some portrait. Is there a function that will resize all of them so that the longer edge will be a certain length?
That would make the good tool perfect. Thanks.

Vlasta (2006-11-26 00:00:00):

Yes, that's actually the default behavior.

birs (2006-11-26 00:00:00):

Gosh! I didn't realize that. I was too much into -hX and -wX, so -^X just did not make it into my consciousness. Sorry to have stolen some of your time.

erikv (2006-11-29 00:00:00):

photoresize rocks!

I just downloaded 1.5 and I think I found a problem.

I'm running it as follows:

photoresize.exe "-ocopy <QT>.\mysrc\<DSTNAME><QT> <QT>.\mydst\<SRCNAME><QT> /Y<EN>" -w480 .\mysrc >rename.bat

With previous versions, this works fine. With 1.5, the report stops at <DSTNAME>. That is, anything including and following <DSTNAME> are not in the report.

For example, the output would look like:
copy ".\mysrc\one-W480.jpg" ".\mydst\copy ".\mysrc\two-W480.jpg" ".\mydst\copy ".\mysrc\three.jpg" ".\mydst\

Any tips?

erikv (2006-11-29 00:00:00):

oops, I meant anything following and including <SRCNAME>. Sorry.

Pierrot (2006-12-12 00:00:00):

Very good !
Is it possible to have a function which could keep the "creation date" and "modification date" of the files ?
(actually all files are recreated, and we lost the possibility to sort by creation date, we need to use EXIF, not useful.)

Vlasta (2006-12-12 00:00:00):

Technically they are new files, but I see that it makes sense. It will be considered for the next update.

Unknown author (2006-12-15 00:00:00):

Downloaded latest version, followed the instructions to the letter, created a shortcut to the executable and modified the Start In directory to a shared network drive Z:\Resized and the application insists on saving the output in the original path of where the file was dragged from. Nothing seems to work. I also notice the help implies the Start In path is surrounded by quotes "" but each time these are entered and applied the entry reverts back to without quotes - arggghhhh!

Vlasta (2006-12-18 00:00:00):

It is not clearly visible on the screenshot, but you must also use the C letter in filename or the -c switch to instruct the tool to put the output files to current directory. The shortcut is only used to specify the current directory. As for the quotes, they are only needed if there are spaces in the directory path.

Unknown author (2006-12-20 00:00:00):

Thank you very much for this brillant and very simple solution.

kkjorsvik (2006-12-20 00:00:00):

I was wondering, Is there away to force the program not to rename the file when it is saving to the current directory. I just ask because since it won't be saving to the same directory, I don't want it to change the name of the file. it would be nice if it would just leave the name alone. Thanks. this is a great program it really does a good job.

Unknown author (2006-12-26 00:00:00):

the program works great but when you drag and drop more than 20 files windows gives and error saying that it doesn't have access to the specified file or route you may not have the appropriate permissions to have access to the element

I received an Olympus E-500 for Christmas. My 1980 Minolta X-700 just wasn't taking the quality pictures and it was time for me to get with the times anyway. So, I've been taking HQ pics (RES 3264 x 2448). Now I wanted to post 108 of them to Google Picasa2 but not at this resolution and 1.5mb per file. I would have to edit one by one with my existing software - YUK!
It only took me about 15 mins including experimentation and I was done! I reduced the 108 files of 315 mb down to 5 mb.
This saved me a LOT of work, thank you and Nice Work!

mexemexe (2007-01-17 00:00:00):

is it posible to resize a whole directory with subfolders of images at once. Or do i have to do each directory at a time. I have about 4 years of pics and i would like to resize them all but will take forever. Thanks/

Vlasta (2007-01-17 00:00:00):

Of course it can resize images in subfolders if you use the -r switch or R letter in filename - read the What's new section for 1.2 version.

Unknown author (2007-01-24 00:00:00):

This is a wonderful tool, and i'm so lucky i stumbled across it. A feature request though:
It would be great if you could put in a command line switch to specify what should be appended to the filename instead of the default. For instance the following commands will have the same output filename

PhotoResize.exe -q40 -^500
PhotoResize.exe -q90 -^500
PhotoResize.exe -^500 -q50

input filename: SNB10272.jpg
output filename: SNB10272-500.jpg

so you can't generate two files of different quality to the same folder. (The second instance will overwrite the first)

whereas it would be better if you could use the command line switch something like:
PhotoResize.exe -q40 -^500 -a"-q40-^500"
output filenames: SNB10272-q40-^500.jpg
PhotoResize.exe -q90 -^500 -a"-optimum"
output filenames: SNB10272-optimum.jpg
PhotoResize.exe -^200 -q80 -a"_thm"
output filenames: SNB10272_thm.jpg

i'm surprised that this hasn't been mentioned before, and i think makes a lot of sense.

Unknown author (2007-02-09 00:00:00):

This is awesome - I used a different tool briefly, but this is better. The only way to improve would be to have an interface where we could enter the sizes and options rather than copying and renaming the file anytime we want to make a change.

Unknown author (2007-03-02 00:00:00):

I have 10,000 documents scanned in greyscale in multiple folders and I wanted to resize them to 50% but I get 'Error occurred' with every one of them. Is it because they're not colour? I've even tried doing a single image and I get the same error message.

Any help would be appreciated.

Unknown author (2007-03-02 00:00:00):

I'm just a bit sad, I can't seem to get it to work, there is something wrong with my settings I guess, but I have no clue. I do as it says here, it works on my boyfriends PC, but not mine. I can't drag and drop images and I can't use the Send To feature. The only way to use it, is to right click on a single image and choose open with, but that takes some time to do a lot of images, and not as smart as this program is suppose to. I have winxp and downloaded the first download for this.

Any ideas or advice?

Vlasta (2007-03-03 00:00:00):

1) B&W jpegs are currently not supported. The tool is primarily for photos.

2) I am afraid I have no idea why you cannot drag and drop files, but it is most probably something wrong with your Windows. The drag and drop is handled in Explorer, the application just receives the path to the dropped files.

Unknown author (2007-03-10 00:00:00):

Canebuono (2007-03-17 00:00:00):

Hello and thanks very much for this wonderful program.
But I didn't understand how to use advanced options. For example, what do I have to write if I want to convert all images in the folder "c:\images" to images which have size 1280x960 and compression quality 80?

Vlasta (2007-03-17 00:00:00):

Then use the following command line: PhotoResize.exe -^1280x960 -q80 C:\images
You can eventually use the -i to overwrite the originals.

Canebuono (2007-03-18 00:00:00):

..And can advanced options be used just from command line? If they can be used also in Windows, how can I rename the EXE to obtain results I indicated in the previous question?
Thanks again!

Vlasta (2007-03-18 00:00:00):

Some of them. The compression quality cannot be set to any value, only 30%, 60%, or 90% can be set by renaming the file. Use PhotoResize1280x960H.exe for 90% quality.

Canebuono (2007-03-18 00:00:00):

Ok, thank you..
And now let me try to be usefull to someone telling an idea of mine :-)
I wanted to be able to convert fast some horizontal and some vertical fotos taken with my 5 megapixels fotocamera, since often 5 megapixels are just a waste of disk space if I'm sure they will not be zoomed (resolution of my monitor is 1280x1024).
I also wanted to overwrite original files, preserve metadata, and I wanted DOS window to close itself.

So, after creating folders
c:\foto_rid\orizzontali and c:\foto_rid\verticali
(I'm Italian),
I created 2 icons; one linked to the command
C:\PhotoResize.exe -^1280x960 -q82 -o -m -i C:\foto_rid\orizzontali
and one linked to the command
C:\PhotoResize.exe -^768x1024 -q82 -o -m -i C:\foto_rid\verticali

So now it's sufficient to copy horizontal fotos in the first folder and lauch the first link, and copy vertical fotos in the second folder and lauch the second link.
Good work, isn't it? :-)

Hi Vlasta,

I re-downloaded the tool and it works great, actually it's fabulous. Saves so much time.

Could you give me your personal opinion as to whether the 400.exe will create good enough photos for a classroom slide presentation or should I go up to 600.exe or 700.exe?

Also, if I add the "N" to sharpen, will that affect picture quality?

Thank you,

Pat (2007-04-14 00:00:00):

Love the tool but wonder how can I resize a batch of photos and locate them in a separate folder from the original pictures for dragging and dropping into a slide show?

For the classroom presentation, the best size would depend on the resolution of the projector or displays. The tool uses relatively high compression by default and I would not be afraid to use 800 or 1024. The file size in kilobytes would still be low enough.
You can put the resized pictures into different folder using the -c command line switch. For example using -cC:\Resized\<PATH><NAME>.jpg will put the pictures in C:\Resized\ folder. You can add command with this options to Explorer context menu and then right-click on multiple selected files or on folder with source files and run the command from context menu.

Unknown author (2007-04-14 00:00:00):

Hello! This program is GREAT! I looked for a program like this for years, and now I found this great image resizer.
Only one small thing what I'm missing: The program cannot preserve the last-modified dates of the images. Please try build in this feature in the further versions. I need the dates of the original pictures. :-)
Congratulations for the developers! :-)

(and one more idea: A "watermark"-maker possibility would be great :))

Unknown author (2007-04-14 00:00:00):

Hi this is realy cool!!

Pat (2007-04-15 00:00:00):

I'm dense, Vlasta. Not a prgrammer, just a student. In order to put the resized pictures into a different folder, where and when should I type the new command? All I've done so far is drag my folder to the tool icon on my desktop and watch the resizing on the DOS screen. Thanks for your patience. This is a wonderful program.

Vlasta (2007-04-15 00:00:00):

Run the tool without any parameters and then put the "-cC:\Resized\<PATH><NAME>.jpg" in the additional options box and click the button to add the command to a context menu of .jpg files and folders.

Pat (2007-04-16 00:00:00):

I ran the tool without any parameters and typed "-cC:\Resized\" but was uncertain of the the correct <path> & <name> to type in before adding the ".jpg" and clicking the button. I tried several but none seemed to work. Once I find the correct path & name, do I still drag and drop from the original folder? Sorry to be so confused.

Vlasta (2007-04-16 00:00:00):

Just type it exactly like I said. The path and name will be taken from the original in that case. And no, you do not drag and drop the files in this case, you add the command to context menu of pictures and folders in Windows Explorer.

Pat (2007-04-17 00:00:00):

In the additional options box,
I typed in -cC:\Resized\<PATH><NAME>.jpg
then clicked the add to context menu button.
Since I no longer drag and drop the folder with my original photos, I do not understand what to do next in order to resize the originals to 800 and send them to the new folder.

Vlasta (2007-04-17 00:00:00):

Right-click on the folder and then click on the added command in the context menu.

Pat (2007-04-18 00:00:00):

Thanks, Vlasta. I did that, the DOS screen appeared, resizing the original photos but . . . where are the resized pictures? I can't find them.

Vlasta (2007-04-18 00:00:00):

They should be in the C:\Resized\ folder. If they are not, something went wrong - remove the command and add it again and.

Unknown author (2007-04-28 00:00:00):

great program! saved me lots of time

Unknown author (2007-04-29 00:00:00):

Hi. Does the program also process tif images? thank you, nice program!

Vlasta (2007-04-30 00:00:00):

No, it is only for color jpg images.

Unknown author (2007-05-02 00:00:00):

Thanks for this program, it's great.
However, can you please add a -c switch variables called something like <SrcFolderName>, so it will create a folder with the files on the destination, when you resize a whole (or more) folder(s)?
I would be happy to see that feature.
And what about a feature to copy files that would be skipped with the S-flag?

I would like to use this program to make a backup of my pictures on an external/network-drive without having the full (orginal) size.

Vlasta (2007-05-02 00:00:00):

The <PATH> variable already works similarly, but it only contains the part of the path from the specified folder to the actual file. If you have your file in subfolders of folder A and process the whole folder A, your subfolders will be re-created. Not exactly what you wanted, but close, I hope.

Both suggestions will be considered for future versions. Thanks for them.

I need to batch crop 4:3 pictures to 16:9 format to show on my plasma screen, can this program do this without distorting?

AlainGdl (2007-05-07 00:00:00):

Version 2 runs differently if input is a Folder or a single file.
ex: PhotoResizeCHR.exe
if specified input is a Directory name

 => output: all created images in current folder => OK

if specified input is a single file name

 => NO output file is created
 (with version 1.5, the outputFile-xxx.jpg was created correctly.

(Is it possible to run v2 like v1.5 without any other parameter)

Thanks for help

AlainGdl (2007-05-07 00:00:00):

additional information...
with a single input file... (with C (current directory)
The output resized image is always saved in C:\ directory...

Vlasta (2007-05-07 00:00:00):

Thanks for reporting the bug, it is now fixed and you may download it right now.

AlainGdl (2007-05-07 00:00:00):

WOW, congratulations for the very rapid update !!!!
It's great to see professional people like you.

Brian (2007-05-07 00:00:00):

Hi, great little app! I need some help with syntax using -c. With the exe in C:\Test, I want to resize files in C:\DirectoryA and have the product appear in D:\DirectoryB. Can you show the exact syntax of this command? Thanks so much! Brian

I tried the following, but it did not work:

c:\Test\PhotoResize.exe -w640 -s "-o<SRCNAME><EN>" "C:\DirectoryA" "-cD:\DirectoryB"

Vlasta (2007-05-07 00:00:00):

use c:\Test\PhotoResize.exe (additional options) "-cD:\DirectoryB\<PATH><NAME>.jpg" "C:\DirectoryA"
-c must contain complete template of the destination path, not just a folder. -o doe not influence the path, only the text sent to the console. Be sure to specify all options before the source folder(s), otherwise they will not apply.

Brian (2007-05-07 00:00:00):

Man that is awesome, works like a champ! Thanks!

Goofy (2007-05-13 00:00:00):

Just wanted to say thanks for a wonderful application! It's easy to download, and even easier to use! 10 out of 10 points for this :o).

greymatter (2007-05-18 00:00:00):

Brilliant piece of software. Am using it fro within my VB program to resize pics for upload to net.
2 questions.
- is there a way to stop the DOS CMD box from displaying whilst the resizing takes place?
- why does PhotoResize640.exe not work?
Thanks and well done.

Unknown author (2007-05-18 00:00:00):

thanks.your program is very very very exellent ;-) :-p
please add noise removal. 'ACD See' can do this for single photo,but you can do resizng for many files(batch)please do it for noise removing.
when we resizing to double size image quality loss.

Vlasta (2007-05-18 00:00:00):

answers for greymatter:
1) If you are calling the CreateProcess Windows API, use SW_HIDE flag in the wShowWindow of the StartupInfo parameter. It should be possible from VB (but do not ask me how to do it, I know very little about VB).
2) PhotoResize640.exe should work, could there be another problem? (when changing tool name, also update the name inside your app)

greymatter (2007-05-19 00:00:00):

You were correct. I had not changed BOTH the call and the exe file names. Works well now. This really is a clever piece of code.

Grant (2007-05-22 00:00:00):

I am nut sue why, but I am experiencing problems with this software "ONLY" after I work with a pic in CorelDraw and export back to JPEG. I then get the sowftware saying an error occoured during conversion.
I export as 300dpi, 32bit cmyk JPEG

Vlasta (2007-05-22 00:00:00):

I am sorry but CMYK colorspace is not supported. Maybe in one of the next versions...

Unknown author (2007-05-23 00:00:00):

Is there a way to prevent the DOS CMD box from showing when calling it from a batch file (.bat)? Great program, btw.

Vlasta (2007-05-24 00:00:00):

I am afraid not, but it should not open its own console window and just use the one associated with the original .bat file.

Moebius (2007-06-01 00:00:00):

I noticed that on my setup, I can only drag and drop up to 21 files at a time. Any more and I get an error about the path.

Any way (besides doing multiple conversions) to select say 50?
I'm running windows XP SP2 pro.

Vlasta (2007-06-01 00:00:00):

That is a known limitation caused by the maximum length of a command line on Windows (the error occurs before the tool is called). You'd be able to process more if the absolute paths to the files were shorter. BTW you can drag and drop entire folders to workaround the problem.

Grant (2007-06-01 00:00:00):

Is it possibel to rotate pics while resizeing them?

Vlasta (2007-06-01 00:00:00):

No, just resizing right now. This might be added in future versions, but I am still not entirely sure if it is appropriate for this tool.

xiar (2007-06-05 00:00:00):

Good utility. Works well.

If you added a GUI to this, it would be fantastic. So you can simply pick the context menu item for a JPG, and a box appears asking the size you want to resize to (and whatever other options). That would be the greatest!

Unknown author (2007-06-11 00:00:00):

Great!! Was searching for something like this for Vista (no powertoy anymore)

This works great and customizable till the end and free...
Nice for my photo albums on the web.
Keep up the good work, you've made at least one guy happy in holland.

andyinjapan (2007-06-14 00:00:00):

Thanks, awesome tool......one question....(please) If I wanted to have a folder on the server and when ever pictures are drop in there they are alto reduced by resizer how can I do this?
Many thanks again for a well made tool :-)

Vlasta (2007-06-14 00:00:00):

Such functionality is not built in. You will have to either use some tool to monitor the folder or periodically run the resizing operation. The S letter will make the tool skip files that were already resized.

Unknown author (2007-06-16 00:00:00):

This is amazing. Thank you SO much for making this!

Unknown author (2007-06-18 00:00:00):

Sorry if these are stupid questions, but:

1) How do I supress the "Press Enter to exit" Message?
2) Is there anyway to change the color depth?

Vlasta (2007-06-18 00:00:00):

1) with -o switch or O letter in filename; 2) no, jpeg only supports 8-bit per channel; B&W and CMYK jpegs are not supported.

Unknown author (2007-06-22 00:00:00):

Great program but i have a question, how can i make one image to be resized to 80x80 ? it seems i only can control one of the sizes and the other is auto.

Vlasta (2007-06-22 00:00:00):

Yes, rename to PhotoResize80x80.exe

Unknown author (2007-06-22 00:00:00):

Thanks a lot for the quick reply, i got confused.

Great program, helps me a lot since i have to put lots of images online everyday.

I can't Change the output folder for Picture Resizer 2.0
I tried the trick with the shortcut but it does not work. What else can I do do send the resized pictures to different folder.

Vlasta (2007-06-23 00:00:00):

Be suer to use the -c switch, it is not visible on the screenshot.

Unknown author (2007-06-23 00:00:00):

Is it possible to automatically detect whether the picture is in portrait or landscape? (e.g. I want to resize all my pictures which are 1600x1200 or 1200x1600 to 640x480 or 480x640 respectively.

Vlasta (2007-06-24 00:00:00):

That is actually the default behavior, where the number specified defines the larger side.

Unknown author (2007-06-29 00:00:00):

ahoj Vlasto. hey do you plan to add control over the quality of the result image? I know you can partly control it by adding L(low), H(high) and G(good) to the filename but what about Qxx where xx is the user-defined quality? Anyway thank you for making this simple tool. I have just started using it but missing the quality control. I usually need to compress the file a wee bit (80-90%). Thx Tomaash

Vlasta (2007-06-29 00:00:00):

No Qxx right now, but there is a command line switch -q. You can add -q80 to the additional options box or if you want to use the drag and drop scenario, you can create a shortcut and add the switch there. BTW there is a Czech version of this page.

Unknown author (2007-06-29 00:00:00):

Thanx for quick reply and I am sorry that I missed the switch in your text. BTW would be more helpful to have list of all the switches at one place here. thanx again. ps: I am quite happy with english version...

stevec (2007-07-14 00:00:00):

I think this is the cure-all I've been looking for, for a very long time. Something I can use (I do computers for a living), something that average and very novice computer users I deal with can use. Since we can't outlaw 5mb JPG email attachments, we must then educate and inform the masses.

Unknown author (2007-07-21 00:00:00):

Your Picture Resizer is excellent - much better than the Microsoft Power toy utility. Please consider allowing the right click to work when more than one photo is selected. That would allow us to resize multiple photos at once. Thank you for your super efforts! Rob

Vlasta (2007-07-21 00:00:00):

...if I remember correctly, when multiple files are selected, then Windows launches multiple instances of the tool, which is a bit confusing, but it should do the job correctly. The context menu command is also available when you click on folders - that might help.

vanthoen (2007-07-22 00:00:00):

Can I use this software on my website?

so that visitors can download and use it


Vlasta (2007-07-22 00:00:00):

By using you mean you want to re-distribute it? It is allowed (even with modified default name) as long as you reference the source.

Why not use F640x640, works fine for me

leen.roger (2007-07-22 00:00:00):


Vlasta (2007-07-22 00:00:00):

Just PhotoResize640.exe should work in that case. FXxY only behaves differently if X and Y are not the same.

Unknown author (2007-08-11 00:00:00):

don't run in recursive directories

Use R letter in filename of -r switch.

ifisch (2007-08-25 00:00:00):

Very nice tool, and superfast. I was looking for a batch resizer for the 16 GB of pictures (taken at 54 megapixels: 6000 x 9000!) from my duaghter's wedding, prior to uploading for printing. PR is a lifesaver.

No, they are currently not supported.

Unknown author (2007-08-30 00:00:00):

Is it possible to resize images so that they will either
a) fit inside the frame 480x272 (for landscape images), or
b) fit inside the frame 272x480 (for portrait images)?

I like to resize images to be viewed on a phone or PSP, where a picture is best viewed as big as possible on the screen even if it means rotating, because the screen can be easily rotated in the viewers hand.

Vlasta (2007-08-30 00:00:00):

I am afraid, that is not possible. You would need to manually split the images on landscapes and portraits and then resize each group with different command.

Unknown author (2007-09-05 00:00:00):

Just want to say.. Thanks! What a wonderful program. It's free, no e-mail hassles and works splendidly.

I hate sites that offer free useful software and then demand your e-mail before they will let you download. They then spam you with advertising (to make money on the 'free' software you downloaded).

Thanks again!

Unknown author (2007-09-08 00:00:00):

Uhhhh... Helo. Im trying to crop my photo, Will this work for that? send back to my email strawberry_n_chocolate20@yahoo.com

My family on the other side of the world is not to computer savvy.
So getting them to resize their pictures was a nightmare until I came across your program.
Thank you.

What a wonderful thing, thank you. But it would be perfect if the filedate of a replaced picture the same as the original file date

Vlasta (2007-10-08 00:00:00):

Since this is not the first that someone requests this feature, it will be added in the next version.

Unknown author (2007-10-09 00:00:00):

It appears the PhotoResizer only supports 24 bit color? I tried resizing 8-Bit & 32-Bit and it shows an error message.

Vlasta (2007-10-09 00:00:00):

Yes, that is correct, greyscale and cmyk jpegs are not supported.

Unknown author (2007-10-14 00:00:00):

This tool would suit me perfectly if the <ROOT> variable was broken down into <DRIVE> and <ROOT> variables. I store my original images on a network drive (X:\Holiday\photo1.jpg), and want to be able to keep smaller versions on my local PC (C:\Docs & Settings\...\My Pictures\Holiday\photo1.jpg). This would also mean that it doesn't matter whether I convert a single image, a folder, or a folder of folders.

That aside, many thanks for a great tool!

Unknown author (2007-10-19 00:00:00):

Brilliant thanks

billybadger (2007-10-27 00:00:00):

Its a lovely tool to work with but I have one problem in that because the 400 is added to the name I can't get my photos recognised at the other end.Is it possible to rename without the 400 being included?

Vlasta (2007-10-27 00:00:00):

Yes, you can either add the I letter at the end of the filename (BUT it will overwrite the source files) or use the -c parameter to customize the output name. Read the descriptions above.

MisterMoonlight (2007-10-29 00:00:00):


I have tried the option to change the DPI of the file header to 300 without resampling the image with D300T added to the .exe file. It is not working for jpg pictures taken with canon camera. I have got an error message saying: "Cannot find JFIF header in: myfilename.jpg". When i am using the option D300 instead, it is working correctly changing the dpi, but also changing the picture dimensions in pixel, with resampling Yerk! I just want to change the DPI settings without touching the picture quality in anyway (no resample/resize). Thanks

Vlasta (2007-10-29 00:00:00):

Hm, when T is not used, the picture is read in any case and if the JFIF header with DPI is not present, the source is assumed to have 100 DPI, so you'll see no error if the header was not found. When T is used, the program looks for the header in the usual place and just overwrites the right bytes copying all the rest. A more robust algorithm that would create the header if necessary is possible, it might be added in one of the future versions.

Unknown author (2007-10-30 00:00:00):

I use it in ASP with ASPexec. It works fine with local images, but when I try to resize an image on a share of an other computer I get an error: "Parameter does not appear to be JPG image or folder"


Unknown author (2007-10-30 00:00:00):

this is a very neat little program. if you are looking to add features though it would be nice for it to auto rotate the image based on EXIF data from the camera.

Vlasta (2007-10-30 00:00:00):

Kobus: it is possible that there are problems with shared paths. Try enclosing the parameter in quotes and if it does not help try mapping the remote server to a local drive.

On rotation by EXIF tags: it is a bit out of scope of this tool, but there is going to be another free application, that would be able to do that.

john (2007-11-02 00:00:00):

PhotoResize is just what I wanted! You have done simply what many other programs have made complicated and expensive.

Unknown author (2007-11-06 00:00:00):

I have problem with batch conversion from Explorer´s context menu. When I mark more than one image the program do nothing. In case of one image resize it works well. What did I do wrong?


Vlasta (2007-11-06 00:00:00):

Resizing multiple images from Explorer's context menu could be a problem, because Explorer runs a separate the tool multiple times and each of them resizes one image. But it should work... Anyway, try running the command from folders' context menu.

Unknown author (2007-11-07 00:00:00):

Thank you, running from folders context menu works well, so I will use this method.

jennypretty (2007-11-11 00:00:00):

This is great. Can you please show me how to resize but keep the same file names?
Right now it adds the 400 at the end of the files.
I want to keep all files as their original file names.

Vlasta (2007-11-21 00:00:00):

You can overwrite the original files if you use the I letter (PhotoResize400I.exe). Backup your images before you use this command.

Unknown author (2007-11-24 00:00:00):


Unknown author (2007-12-01 00:00:00):

great tool, thanks for saving me much time

Unknown author (2007-12-05 00:00:00):

Perhaps a new feature would preserve the time stamps of the original image so that you can continue to keep track of when photos were taken without having to look at the EXIF metadatas. Thanks!

Unknown author (2007-12-13 00:00:00):

Do you have Japanese directions?

Vlasta (2007-12-14 00:00:00):

No, just the ones you can see in the upper right corner. The pages were translated by volunteers.

Unknown author (2007-12-26 00:00:00):

This is a very cool tool. I find it only handles 25 files at a time else I get an error - "The data area passed to a system call is to small". I'm running Vista, so I'll blame it on Microsoft. Any ideas on how to fix it would be appreciated.

Vlasta (2007-12-27 00:00:00):

...odds are there is a problem with the 173rd file and the later...
As of the error when dragging and dropping more than 25 files - it is caused by maximum length of command line - just drag and drop a folder instead of individual files.

Unknown author (2008-01-08 00:00:00):

Very cool. Works just the way I prefer to do conversions. Thanks.

Unknown author (2008-01-11 00:00:00):

BossTurbo (2008-01-14 00:00:00):

Great Software! It took me a couple hours to figure out how to set up all the features I needed, but I got it working smoooth now via batch file. Would be nice if it had an ability to remove all EXIF data but leave only the orientation flag. This way when viewing the files they will be rotated correctly (or just rotate the jpg automatically). I don't need all the EXIF data which just bloats the file size.

Vlasta (2008-01-15 00:00:00):

You can rotate by EXIF tag, remove EXIF (since it is already rotated) and resize using RW Photos, but you need to setup the operation correctly. Here is how to configure RW Photos to rotate and resize images for web.

If this would support .png format then it's perfect.

Unknown author (2008-01-22 00:00:00):

I love it. It's great. It's simple
BUT!!!! mine stopped working after 10 pictures. I am running vista (errr..)
I tried Redownloading and re-running but... not working. SAD.. :-(

Vlasta (2008-01-22 00:00:00):

Maybe you are having problems with command line length - read one of the early comments on this topic. Or...if it worked with one image and now it does not work with the same one, check for viruses on your computer.

Unknown author (2008-01-22 00:00:00):

Vlasta, I can not change the DPI of an image without resampling too (i.e., DXT does not work). I get the error: "cannot find JFIF header". The file may not have an EXIF, but it does have a horizontal and vertical resolution embedded. Surely you can read that?

If you want a sample, here is a book cover from Amazon with a DPI of 2x2!


Vlasta (2008-01-23 00:00:00):

You are right, the file does have a JFIF header. But it is not in the typical position at the start of the file. The DxT version is only able to work if the JFIF header is in the beginning of the file and it would need to be fixed in next version.

kazmo (2008-01-25 00:00:00):

just downloaded this and figured it was going to ... not be so good. i mean come on, a DOS window after each run? wow. i was so wrong. what an awesomely simple program that makes resizing rapid and idiot-proof. based on first-look, this is a must-have for webmasters that need to frequently post thumbnails. bravo! (i will be contributing!)

oops, found it ... it's -i ... in place ...

Vlasta (2008-02-01 00:00:00):

No, resizing and changing DPI to custom value is not possible in one step, but the second step is very fast and does only overwrite the two numbers in the header.

Unknown author (2008-02-11 00:00:00):

kewl software!!!!

Unknown author (2008-02-20 00:00:00):

apparently it only works on 24bit jpg's not 8bit jpg's

PeterJZ (2008-03-02 00:00:00):

Vlasta, I need your help, please.

I am calling PhotoResize from Access 2007 with a Shell command. It works fine as long as there are no spaces in the path or file name. I have tried everything I know to put quotes around the path, but no luck. My code looks like this:

strFullPath = "c:\database development\test.jpg"
Shell("c:\programs\PhotoResize400.exe -n -q80 -o " & strFullPath, vbHide)

Can you possibly help?

Vlasta (2008-03-02 00:00:00):

Well, I do not use VB, but the quotes really should do the trick.
Shell("c:\programs\PhotoResize400.exe -n -q80 -o """ & strFullPath & """", vbHide)

PeterJZ (2008-03-02 00:00:00):

Thanks a million, Vlasta, it works as you suggested! And thanks also for a fantastic program to work with!!

Unknown author (2008-03-02 00:00:00):

I wish the program could resize PNG, GIF and MBP files!

Unknown author (2008-03-16 00:00:00):

I like your program. Is there a way to name the output file with its dimensions (in correct order)? PhotoResizerF1200X900.exe seems closest to what I want: a 3648x2736 file gets named MyPhoto1-F1200x900 and 2736x3648 gets named MyPhoto2-F1200x900. I would like the 3648x2736 file named MyPhoto1-1200x900 (no "F") and the 2736x3648 named MyPhoto2-900x1200 (no "F", numbers in correct order). Thank you.

Unknown author (2008-03-17 00:00:00):

I like the fact that it just works without a setup.exe
But I'm missing an option to resize it to a percentage rather than pixels.

Cheers martin AT add-your-page.com

Vlasta (2008-03-18 00:00:00):

The option is there and much more. Read the description ^.

John (2008-03-25 00:00:00):

There aren't any Power Toys for Vista, so I'm trying to use this to emulate the XP Power Toy which resized pictures. I've added the program to the context menu. When I right click on a folder containing pictures, the Picture Resizer option appears. However, when I right click on an individual .jpg, the Picture Resizer option does NOT appear. Is there some trick to getting the Picture Resizer option in the context menu for an individual .jpg?

Vlasta (2008-03-25 00:00:00):

You observation is correct. I am not sure, but it seems like the behavior of Vista was changed recently. I am going to fix this in a couple of days.

Unknown author (2008-03-26 00:00:00):

Great tool - Thnaks!

Unknown author (2008-04-04 00:00:00):

this looks cool, thanks so much. what do i do if i want to both 1) skip files that are already smaller than the required size, and 2) set output quality to 'high'? do i rename the .exe to PhotoResize800SH.exe? (i want 800px-sized pictures)

also, how to i add these options to the explorer's menu? entering -h doesn't seem to work.

thanks in advance. cool little program it is.

Vlasta (2008-04-04 00:00:00):

Yes, you can combine the letters, both HS and SH after the number are OK. If you want to use the command line flags while adding command to menu, put them into the additional options box and be sure to read the advanced options page, because the switches are different from the letters. For example, there is no -h for high quality, you should use -q90 for the same effect.

Unknown author (2008-04-04 00:00:00):

thanks for your reply. i seem to be getting what i want.

a couple of questions:

1) talking of quality, does PhotoResize actually resample pictures? if yes, what algorythm is used?

2) when using command line flags in the additional options box, we're basically overriding options specified in the filename, right? i.e. if my filename is PhotoResize800HS.exe and my additional options are -o-q95-n, the program will ignore the H in the file name and use the -q95 setting? will it still do the 'S' part specified in the filename?

3) i cannot seem to be able to apply the command to several files at once by selecting them in either TotalCommander or Explorer, right-clicking and selecting 'resize files'. it works great either on 1 file, or on a folder. i'm on win xp sp2.

Vlasta (2008-04-05 00:00:00):

1) linear interpolation for magnification, pixel coverage for minification (weighted average of the original pixels); with gamma assumed to be 1.6
2) yes (though, you should put space between the switches: -o -q95 -n)
3) ...hard to tell why, it works on my computer and it is actually under Explorer's control.

Unknown author (2008-04-05 00:00:00):

>> though, you should put space between the switches: -o -q95 -n

then i think this should be mentioned specifically in the shell integration part of the description. it's really not so obvious :-)

still can't get it working on several selected files in a batch. folders work great.

Unknown author (2008-04-08 00:00:00):

Great program, I use it all the time. However, has the problem of choosing many files (more than command-line length) been solved yet? I still get errors with version 2.0 when dragging like 100 files onto the Icon on my desktop. If you could get that licked, this would become the indispensible file resizer.

Vlasta (2008-04-08 00:00:00):

Unfortunately, that is a Windows problem (or more precisely "limitation") and it occurs before the program is even started. Report it to Microsoft ;-).

Unknown author (2008-04-14 00:00:00):

I'm using Windows 98 but when I try to run the Windows 98 version of picture resizer it says that it expects a newer version of windows

Vlasta (2008-04-15 00:00:00):

...I have checked it and you are right, there is a compatibility problem. It should be fixed now, but there may still be small problem with specifying some parameters in filename on Win98.

Unknown author (2008-04-15 00:00:00):

a very good software for sizing down the photos

Unknown author (2008-04-15 00:00:00):

saachi - Just making a quick suggestion which I'm sure you would have already considered. If resize dimensions are a different ratio then the sources then possibly just crop to maintain aspect (via switch?). This is otherwise the most functional (besides cmd window but thats negligible) and esiest resize app around. Props.

Unknown author (2008-04-16 00:00:00):

Very nice!!!! Thank you!

Hyland (2008-04-17 00:00:00):

This program is excellent!

I am using the program to make a resized copy of my Master Archive of personal photos (the Master Archive is too big for my laptop) to make a Resized Archive in a new directory.

1) When resizing photos to a new directory (using the R command) is there also a command that will copy non-picture files (movie files, pdf, etc) that were skipped?

2) Is there a way for the program to skip photos that were resized in an earlier resizing session? This way I do not need to resize photos already in my Resized Archive, just the new ones I add to the Master Archive. (Resizing the entire archive takes 7+ hours on my computer)

Suggestion for future version: Have the command prompt window show a status counter (example “Resizing 3 of 8567”)

Thank you for your time!

Vlasta (2008-04-18 00:00:00):

1) Unfortunately no. I guess copying all files not matching *.jpg should be possible using some scripting language. Definitely on Linux and most likely on Windows, but I am no expert on this ( try http://en.wikipedia.org/wiki/Windows_Script_Host ).
2) Probably no. The -s switch or S letter at the end of the tool's filename will make it skip files that are already smaller than the specified size, but if I understand you correctly you would rather need to skip files modified prior to some given date. Maybe in one of the next versions...

Unknown author (2008-04-18 00:00:00):

Really nice program! Just one thing: can you please add a parameter to hide the command prompt window? Thank you in advance!

Vlasta (2008-04-18 00:00:00):

There is the -o parameter, which closes the window after the work is done without need to wait for Enter key. Other than that, the output is generally useful, because it will show if the resizing was successful or not. The window can only be hidden if the tool is started from another application with appropriate Windows API call.

Unknown author (2008-04-19 00:00:00):

I see. I use the -o parameter. But I usually process one or two pictures at time (e.g. to write an email) and the prompt command window is kind of annoying (no offense). Please, consider since it's just a simple feature that will be optionally used by us. Let the user make a choice here too. Please! :-)

russell (2008-04-21 00:00:00):

This program is so much fun to use. Thank you :-)

The filesize comes out so small, but the quality still looks great to me. I've been using this app to compress my images even though I'm not decreasing the pixel size. I just have to keep changing the pixels on the app because my images are all over the place. Is it possible to have the app recompress without resizing? I realize it's kinda silly since it's called "photo-resize" but just thought I would ask. :P

Vlasta (2008-04-21 00:00:00):

Well, yes, PhotoResizeP100.exe will resize to 100% and re-compress the image. Some quality will be lost of course, but the file size is likely to decrease, because image from cameras are usually using a very high (often unnecessary (the sensor is not that good anyway)) quality setting.

russell (2008-04-22 00:00:00):

ahh, i didn't think about using the percentage thing. excellent work :-)

Hello, I’ve been looking for months for a tool that actually does image resizing by maintaining quality of the picture. I’ve stepped over a new tool that I’ve found at reshade.com which satisfied me completely so I thought that there must me more like me out there, regular people who were amazed by this video but didn’t quite know what to do with it, who just wanted to use the feature in it.

Unknown author (2008-05-20 00:00:00):

Awesome tool Vlasta! This is gonna save sooo much space on our file servers! Our users take and have thousands of jpegs in their home folders on our file server. They don't have the knowhow so off course they take all their pictures with their cameras on highest possible resolution without the need for it. Just yesterday I helped a user convert a folder with 4000 jpegs in it, weighing in at 2.5GB! Now the same folder is 135MB. Incredible space saver for large user number environments!

Unknown author (2008-05-21 00:00:00):

I plan to use your software in a batch script, and cannot find a way to terminate your program. Is there a way to terminate the application without having to press 'Enter'?

Yes, the -o switch or the O letter at the end of the filename.

Awesome! Can the shell integration be set up to show only for picture formats instead of all files?

Vlasta (2008-06-20 00:00:00):

The context menu entries show for .jpg files and for folders. If you are asking whether it would be possible to scan the content of the folder and only show the commands if there are .jpg files, then it would be technically possible, but not practical (what if you clicked on C:\ ?). If you are using the tool from the Send to menu, then it indeed shows for all files -> try the true shell integration for better results.

'Remove all' does not remove all!
'Resize image' is still there, and when I click it it takes me to chose an application!
How do I get rid of it?

I want rid of it because I dont want a window opened for each resize.
The Windows resizer does not do this and is much quicker.

duncan (2008-06-20 00:00:00):

Very nice tool.

On my NT4 workstations I get error messages when I tried to run the "Windows NT4, 2000, XP, and Vista" version. ("Not a Windows NT application" error message.)

No problem though -- I found the "Windows 98 and Me" works great on NT4.

Vlasta (2008-06-21 00:00:00):

Thanks, Duncan, for pointing that out, I have fixed the descriptions (the 9x version actually works everywhere, but does not support unicode characters).

Fivish, I guess you have moved (renamed, deleted) the PhtotoResize.exe file and therefore Windows cannot find it anymore and asks you to choose an application. Try renaming it back to what it was when you have added and clicking the Remove All button again. Also, make sure that you are using the same version of the tool for removing as you have used for adding. If everything fails, you can use regedit to remove it - open it and search fro PhotoResize and delete all found PhotoResize+8 random characters keys.

Unknown author (2008-06-29 00:00:00):

man that's awesome!!!

Garance (2008-06-30 00:00:00):

Great tool. Feature suggestion for handling renaming:

If you have a file that already has the size as part of its filename, say file-4000.jpg, and want to resize it to 2000 wide, fileResizer will call it

It would be great if it could detect if the filename ends with -xxxx.jpg. And instead call it, e.g.


This would help in writing external scripts that look for images based on their sizes, etc.etc.

itsjustmatt (2008-08-20 00:00:00):

This software is great. Amazingly flexible. One problem though (version 3.0): the "I" option doesn't seem to be working correctly for me. If I drop a folder of pictures on "PhotoResize1024IHR.exe", the resize of all pictures goes great. However, on some folder's the pictures get overwritten and some folders they get renamed. There doesn't seem to be a pattern, but repeated attempts get the same result on the same folders. Dropping individual files gets expected results. Any idea?

Vlasta (2008-08-20 00:00:00):

Unfortunately, I have no idea why is this happening. I am going to do a couple of tests and hopefully I will be able to see the error myself. If you find a 100% sure way how to replicate the problem, please let me know.

Unknown author (2008-09-04 00:00:00):

Ahoj Vlasta,

thank you for this great application. It saved me a lot of work in the past. Currently I'm trying to create a batch which should be run once a week on a network drive and recursively resize all pictures with a size bigger than a width of 1280 pixel and reduce it if needed. My problem is that pictures that already have been resized are touched every time I run this batch:

PhotoResize.exe -w1280 -i -m -o -r G:\

This leads into a constantly decreasing quality.

Is it possible to tell PhotoResize not to touch pictures that already have a width of 1280 pixel ? Due to the amount of pictures it's not possible for me to create the resized pictures in another directory.

The specs: one directory with lots of subdirectories, every picture with a bigger width than 1280 pixel should be resized once an then never been touched again when photoresize runs again.

Any idea ?

Thank you very much for your work as well as for your help,

Unknown author (2008-09-04 00:00:00):

Oh, ich forgot to ask whether it would be possible for one of the next version to tell photoresize to resize pictures regardless of height oder width to a maximum of x pixel. Example: a picture should not have more than 1280 pixel in width/heigth.


Vlasta (2008-09-04 00:00:00):

Hi Fred, both functions are already available. Use the -s switch to skip images, which are already smaller and use -^1280 instead of -w1280 to resize pictures to maximum size of 1280 pixels vertically or horizontally. Or use -f1280x1024 to make them smaller or equal to the given frame.

děkuji mnohokrát !!!

"-f1280x1024" was the option I was looking for. It seems that I didn't understand that frame stuff when reading your documentation.

Nevertheless, all pictures are touched independent if they are smaller or not. After running the batch 3 to 5 times they aren't touched and the filesize isn't reduced anymore. I checked this intensively: The sizes are reduced by some byte only and the quality doesn't change. So I can live with this.

Again, thank you very much,


Unknown author (2008-09-09 00:00:00):

Wonderful! Makes small, compact files, not the huge files other resizers do! I love it.

Unknown author (2008-09-12 00:00:00):

This is a quality little program, I wish there was something similar for audio!

Unknown author (2008-09-17 00:00:00):

Do yo have a DLL that we can integrate in our program?


Unknown author (2008-09-24 00:00:00):

This program is pure gold! i can't believe how good and simple it is!!
i can rename it with the options that best fit the parameters of my gallery site, then put it up or download on my server
all the users have to do is drag their pics onto this exe? no config on their part? don't get easier
personally, i just have multiple shortcuts for the most used settings, its so friggin great!

Great program...I have a question though. I have a couple hundred pictures that I have resized to w108xh108. As new pictures are added to this network drive they will be the wrong size by default. I am going to setup a batch file to run the photoresize nightly. However, I need them the overwrite the existing file and keep the same name and extension. Is there a way to do this?


caracole (2008-10-01 00:00:00):

"Bravo" for this little program!
It would be nice if retained a minimum EXIF information.

Thanks, Pierre

caracole (2008-10-01 00:00:00):

Ce logiciel ne nécessite aucune traduction - voilà pourquoi il est "presque" parfait

Vlasta (2008-10-02 00:00:00):

Chris: yes, files are overwritten by default, but you'll probably want to specify different folder (to prevent resize version of resized version ...) or at least use the switch to skip files already smaller than the specified size (btw w108xh108 does not exist).

Caracole: exif is preserved if you use the the right switch (look in What's new in version 1.4).

Unknown author (2008-10-03 00:00:00):

Thanks for the reply Vlasta...This is what I changed the executable to "PhotoResizeH108xW108.exe" and now the JPG dimension are 108x108 so not sure what you mean by they dont exist. Also when I dragged the picture folder to the above EXE it did not overwrite the files by default. It created a second instance of the file called "originalfilename -H108" I had to use a mass rename tool to delete the -H108 off the files. I want the pictures saved in the same folder with the same name. Thanks again.

Vlasta (2008-10-03 00:00:00):

I meant if you run the tool twice, the pictures generated in the first run will be overwritten in the second run. If you simply want to overwrite files, use the -i switch or I letter in the end of the filename. PhotoResizeH108xW108.exe is not valid, it effectively equals PhotoResizeW108.exe. You can only use one of the ways for specifying size, depending on what you want - read carefully the descriptions. If you want the pictures to have maximum of 108 pixels in either direction, use the very basic mode without any letter -> PhotoResize108.exe (eventually PhotoResize108I.exe to overwrite source files).

Unknown author (2008-10-05 00:00:00):

Great resizer, what I can say...
The only one thing: I want to run resizer from Excel or other program using VBA. I tried to use Shell command, but it doesn't work. Probably I do something wrong. Can you please tell how I can call this resizer and convert files from Excel or other program using VB or VBA?

Vlasta (2008-10-05 00:00:00):

Personally, I did not try that, but others did. Click on the "Show all comments" link above and search for VB. There are several comments on this topic, including examples.

Unknown author (2008-10-06 00:00:00):

E1 (2008-10-09 00:00:00):

Hi, great software. When I resize an image to a different hight the image decolors and becomes a little darker. Is there a way to correct this?

Vlasta (2008-10-11 00:00:00):

I suppose this could be due to a color profile being removed from your .jpg file. Try keeping the metadata using the M letter: PhotoResize400M.exe

LittleLew (2008-10-11 00:00:00):

You might make it clear that the reduction is based on the jpgs longest dimension.

This works great for my PC users. Can you point me to an equivalent Mac app?

Vlasta (2008-11-12 00:00:00):

Number of images or folders processed at once is not limited, but the length of command line parameters in Windows is and drag and drop action in Explorer makes use of it.

Poznekio (2008-12-18 00:00:00):

Picture Resizer is a good program, but it has poor documentation. Here is a link to a message on this subject that I posted more than a week ago:


I was hoping that message would lead to better documentation, but unfortunately it was apparently ignored by the program's author.

Vlasta (2008-12-18 00:00:00):

Almost all options are described on this page or on the advanced settings page. I agree that documentation on this page is far from ideal, but at least it gets from simple things in the first version to the more complex one in later version. BTW feel free to compile the list of option yourself in the mentioned topic...

Poznekio (2008-12-18 00:00:00):

Hi Vlasta,

I would be happy to help with the documentation as you suggested in your post above ("...feel free to compile the list of option yourself..."). But I think you could do it far more easily than I could do it. That's because you know all of the options. If I attempted to compile the list of options, I would apparently have to do a lot of detective work because I get the impression (from browsing your forum) that there are options that are not mentioned in your documentation. In fact, I notice you used the word "almost" in your post above when you said "Almost all options are described...".

It would be tremendously useful to your users (and greatly appreciated) if you would simply make two lists of the codes with a brief description of each code. The two lists would look something like this:

I - do in-place resizing.
M - copy metadata.
R - scan for images recursively.

-s - invert the "skip files that are already smaller than the specified size" flag.
-n - invert the "sharpen the resized image" flag.
-t - invert the "independent size and DPI" flag.

Poznekio (2008-12-18 00:00:00):

It just occurred to me that the sort of complete lists that I suggested above could possibly cause confusion when read by users of older versions. But you can deal with that issue simply by putting the following note at the top of the list: "This list is for the latest version, which ideally you should be using. If you are using an older version, some of these codes may not work."

Vlasta (2008-12-19 00:00:00):

OK, I'll try to find a bit of time and update both the tool with a few things people requested and I'll do something with the documentation during the Christmas season, probably a separate page. Actually, in one of the older comments, there is a suggestion to make a web wizard that would let user enter the options and generate the filename for that options. I think that quite smart and worth doing at this level of complexity.

Unknown author (2008-12-21 00:00:00):

I love this application, however... is there any plans to make it compatible with png and gifs to?

rcv (2008-12-24 00:00:00):

This is a great little program! I am using it to batch convert thousands of pictures to a mirrored directory structure, with the original being my full resolution pictures, and the mirror being my low res conversions for my digital photo frame. It would be very helpful to have an option to syncronize the directories, only convert new or updated files, and possibly deleting files if they have been deleted from the source directory.

Vlasta (2008-12-25 00:00:00):

No .png or .gif support is currently planned, it would mean a significant increase in size over the current 300kB.
Skipping files already existing in destination location will be added in next version. Not sure about deleting files - that sounds a bit dangerous.

Wade (2008-12-29 00:00:00):

This program ROCKS!!! Thank you for your efforts on this!!

BossTurbo (2009-01-04 00:00:00):

rcv, use robocopy. There is a /MIR option that will sync up the directories. It comes with Vista and it's a free download for XP.

rcv (2009-01-05 00:00:00):

Thanks, BassTurbo. I was not aware of Robocopy, and it will be useful. However, the planned feature for the next release of Picture Resizer will be very helpful to me, since I'm not looking for an exact copy of the directory, but a resized version of the directory tree. The deletion part isn't so important, but I want to be able to make a few edits or updates to the original pictures, then have the resized directory tree get the same updates, only resized to a smaller version. Currently, I either have to manually update the edited files, or redo the whole tree, which takes some time. I have about 15,000 pictures I batch resize to the cloned directory tree.

Vlasta (2009-01-05 00:00:00):

rcv, a word of warning. If a file exists in the destination folder, it won't be resized again with the -u switch. Reading your last comment, it would seem that the tool would actually need to check timestamps of the files and also process files that were updated, not just added. Is that so?

Poznekio (2009-01-05 00:00:00):

Hi Vlasta,

I notice that are major new improvements in the documentation, including the "Renaming wizard" and the "Name codes overview". I applaud you for doing those great documentation improvements! In an old post, I said "Picture Resizer is a good program, but it has poor documentation". I am happy to see that, with the recent improvements, Picture Resizer now has good documentation. Thank you very much. Keep up the good work!

Vlasta (2009-01-05 00:00:00):

I'll try ;-). Thanks.

Unknown author (2009-01-06 00:00:00):

Is there a way or chance that PictureResizer will work also with png and not only jpg files? Thanks and Happy New Year!

Unknown author (2009-01-06 00:00:00):

sorry remove my comment, just saw the same question answered a few days ago... Great Work! Will donate right now!

Vlasta (2009-01-07 15:05:34):

rcv, I have made a small modification that takes time stamps into account, please re-download the tool if you wish to use that feature.

Unknown author (2009-01-09 16:21:56):

I've just tried to drag 82 jpegs onto the app to resize but got a Windows access error. It worked fine when I reduced the selectionto 20 images. Is there a max number of files I can drag onto the icon at once?

Unknown author (2009-01-09 16:27:49):

To be more specific - reducing the number by 1 each attempt showed that 24 files with total size of 470kB was the max I was allowed to drag in one go. Fantastic software, I just need to figure out what I'm doing wrong!

Vlasta (2009-01-09 22:34:52):

There is no explicit file count limit, but Windows has limitation on command line length and the error occurs before the tool is launched. You can drag and drop entire folders...

Unknown author (2009-01-12 10:00:16):

Thanks for your quick answer and solution. Dropping a folder worked perfectly, and blisteringly fast too! The 'resize to target kB' feature is a real life saver. Thanks for such a flexible and simple tool. Time for a donation I think.

Unknown author (2009-01-21 14:43:56):

Thankz for Q command.

Example for Hi5.com

640 = max long side 640 pixels (width or height)
Q96 = Quality 96%
S = Skip file that dimension is smaller
O = do nOt wait for enter / no Output
N = sharpeN (unsharp mark)

Vlasta (2009-01-23 09:15:35):

Poznekio, you'll have to remove individual entries in registry. Search for PhotoResize under HKEY_CURRENT_USER\Software\Classes There are multiple emtries for folders and .jpg files.

Poznekio (2009-01-23 10:15:01):

Hi Vlasta,
Thanks for your reply. But unfortunately your solution is not user-friendly. So please add the following feature to the next version of Picture Resizer: the ability to remove *one* context menu item (without removing *all* context menu items) in a user-friendly fashion from inside the Picture Resizer user interface. Thank you very much.

Unknown author (2009-01-23 11:38:12):


 Its awesome tool. I need a clarification on the conversion of the JPEG picture from 1200*800 to 400*514.
 I tried renaming to PhotoResize400_514 as * is not allowed in naming of file in windows.

Please advice.

Shadrackc (2009-01-24 03:47:44):

Feel stupid asking, but I can't get it to send resized pictures to a specified folder. Tried creating the shortcut and changing properties, but no matter what I do it puts the picture in the original folder. Help! Other than that, what a great program. Ok, forget my question, I just read in the comments that you can't see the -c in the screen shot so I added it and it works! Vlasta, what a great job!

Vlasta (2009-01-24 09:17:51):

Use PhotoResize400x514.exe or just use the renaming wizard above.

Currently the extensions on some of my JPEG files are upper case (".JPG"). Using command line parameters (not application-name codes), I would like to change all of the extensions to lower case (".jpg"). I want it to be done recursively and in-place. And I want to keep the original filenames of the images. Please post the command line parameters that will accomplish that.

Thanks yhis is good tool! It's make many people happy))

Vlasta (2009-02-17 16:03:45):

Poznekio, if you only want to rename the files and not resize them, I would recommend using some other tool for file manipulation. You can resize to 100% (with -p100) and hence leave the size as it was, but the quality may drop.

If you also want to resize the pictures, try using -c"<ROOT><PATH><NAME>.jpg" together with the other switches (-r and something to specify size). But be aware that you may lose a file if the processing fails. Normally, with the -i flag, the original file is deleted after the resized version is successfully created. In this case it is being directly overwritten and if it fails, there is nothing to go back to.

Poznekio (2009-02-18 06:58:44):


This string does not work:

-o -^200x200 -i -r -c"<ROOT><PATH><NAME>.jpg"

Any ideas?

Vlasta (2009-02-18 15:56:22):

Hm, you are right, it looks like the originals cannot be directly overwritten. You'll have to use another tool to change big JPG to small jpg.

supremeox (2009-02-19 16:23:12):

Great tool. Just what I've been looking for. I'm having trouble with the -m flag:

PhotoResizeX725C "F:\Media\Photos and Videos\My Photos\Masters\Not Uploaded\_full_photos" -o -n -m

The output file does not retain any metadata, either EXIF or IPTC (is that supported?) Am I doing something wrong? I downloaded the version linked from this page: http://www.rw-designer.com/NT/3.5/PhotoResize400.exe

Thank you.

Vlasta (2009-02-20 10:46:29):

The command line is processed from left to right -> flags only affect files specified after them. Put the flags in front of "F:\..." and all will be OK.

Is it possible to on every startup automaticly scan a folder and resize updated files without any draging?

Vlasta (2009-02-26 08:47:11):

You can make a .bat file or a shortcut with command line parameters for that.

Unknown author (2009-02-28 16:26:53):

Cropping is currently not supported, you can try one of the other modes: pr400x300.ex, prF400x300.exe, or prG400x300.exe

Teri (2009-03-04 06:11:14):

I just downloaded Picture Resizer 3.5 and can't make it work. When I click on the icon on my desktop, I get a black screen with cursor (similar to DOS) and a pop-up message box that tells me to "drag and drop JPG files or folders on the application icon in Windows Explorer or Tupe full path to a file or folder on command line as a parameter or add commands to context menu of Windows Explorer" followed by a Command name option and and Additional option space."

First, I don't see any "resizer" option icon in Windows Explorer and I don't understand the rest of this.

All I want to do is resize a few pictures currently on my desktop and in various files in my Documents folder, and some documents I will be scanning onto my computer. What do I need to do?

Vlasta (2009-03-04 10:32:52):

You just need to do what it says. Drag your photos with your mouse and drop them over the PhotoResize icon. This will create a resized copies of your photos.

Mandy (2009-03-05 02:50:34):

I really like your tool but I'm having a little trouble. I need to use the command line because I need to keep the original names of my photos exact. I've managed to learn to do this though I'm not familiar with programming at all but I'm having trouble using both the "include subfolders" function and the specify output function at the same time. I can do either but not both. This is what I'm putting in:
H:\>PhotoResizek100CR.exe "-cH:\zRESIZED\<PATH><NAME>.jpg" H:\zToResize

I've tried it with -r stuck in various places but I'm not sure what's meant by invert. Speaking of which I tried to make it not to skip the smaller sizes so I'd have a complete set in the "Resized" folder but maybe this doesn't work with kilobytes? It's not a big deal

Anyway, this is terrific and I think it will work for me. Your advice will be appreciated.

Vlasta (2009-03-05 10:50:40):

You command line looks fine, maybe you can leave out the C in the filename, because you are using the command line switch.
PhotoResizeK100R.exe "-cH:\zRESIZED\<PATH><NAME>.jpg" H:\zToResize
Are you sure, it does not process files in subfolders using these settings?

The "skip smaller" option really does not work with the resizing to kilobytes options, it is unknown what the size of the resulting image will be. But you can use the skip existing option PhotoResizeK100RU.exe

Unknown author (2009-03-08 22:09:35):

Great tool for my father. He will be happy!

Unknown author (2009-03-15 10:33:12):

Hey, I cannot remove the context menu item even though I click on "Remove all" button. I am using PhotoResize400.exe, but I believe I created the right click context menu item using PhotoResize300.exe or earlier version. What can I do to remove those unwanted items??

Vlasta (2009-03-15 10:56:00):

Yes, there was a change related to Vista in one of the earlier version in the context menu handling. If you have created the entries with older version, download that older version (just change the version in the url) and click "Remove all" in that version. Or you can use regedit to remove them.

Hi there! Tool is great but I'm trying to do a resize and I cannot get the desire result...I want to resize pictures to 148x174 and also make their kb size between 3.1 and 3.8. Any idea??? Thank you!!!!

Vlasta (2009-03-21 01:15:29):

You can only choose one criterion, either dimensions (PhotoResize148x174.exe) or file size (PhotoResizeK3.exe).

Robby (2009-03-30 10:37:46):

Recursive works fine creating sub folder where necessary, but I would appreciate the capability to select a source subfolder and create it in another path with the new, resized pictures. (I have a source folder with subfolders for each month, and don't want to re-copy all folders each time.)

If I select one subfolder, the re-sizer will not create that subfolder in the target path.

Vlasta (2009-03-30 11:13:42):

I am not quite sure what is the problem in this case. Can't you simply run the resizer on just one subfolder?

Robby (2009-03-30 16:19:45):

If I select one subfolder, the re-sizer will not create that subfolder in the target path.

Vlasta (2009-03-31 08:29:21):

Not by itself, that is true. But it will, if you add it also to the target path template.

Or maybe just using the "skip existing files" option will work fine for you.

Unknown author (2009-03-31 15:56:38):

Also try Microsoft power tools image re-sizer it's free as a XP plug in, its good for basics and does batches.

Robby (2009-04-01 10:01:28):

Sorry, but MS Image re-sizer doesn't allow me to preset the size that I want. I have to choose each time.

I'm afraid that my powers of description aren't too good:
I have various image source folders which may be at different levels, but all have the same naming convention, for example:
C:\UK photos\2008\0108\....jpg
C:\UK photos\2008\0208\....jpg
C:\Foreign Photos\2009\0209\....jpg

I want to resize the jpg files and retain their folder names so that I will get:
H:\Resized Photos\0108\....jpg
H:\Resized Photos\0208\....jpg
H:\Resized Photos\0109\....jpg
H:\Resized Photos\0209\....jpg

The command that I am currently using is:
-o -w240 -r "-cH:\Resized Photos<PATH><NAME>.jpg"

but this doesn't create the folder name for me, it just puts the jpegs into H:\Resized Photos. Is their a different parameter that I should use to make this work?

Vlasta (2009-04-02 00:21:41):

Well, you should probably add an extra backslash to the command "-cH:\Resized Photos\<PATH><NAME>.jpg".

Whether a folder is created or not depends on the processed folder. If you run it on "C:\UK photos" the 2008\0108 should be created in the destination.

If you want to select just one subfolder and still create it, you'll need to change the command line like this: ... "-cH:\Resized Photos\2008\<PATH><NAME>.jpg" "C:\UK photos\2008".

I'd like to suggest that an option is added so the resulting file keeps the original's orientation. I dunno if that info is stored in the EXIF, but I believe so.

Vlasta (2009-04-07 09:30:43):

Copying the EXIF block is already possible via the M letter or flag.

Excuse me but I had a problem with your 3.5 version

I tried to resize an image with the retarget method and 8 images was successfully resized but one was ruined I dont know really whats the problem but im afraid that this problem may happen again


Vlasta (2009-04-22 09:11:25):

Could you send me the original and the damaged image the setting used to info@rw-designer.com?

Unknown author (2009-04-22 11:51:23):

Great utility. Can I suggest 2 things/enhancements?

1) When using the "U" option to ignore files already converted. Add an option so if a SOURCE image has a newer date than the already existing DESTINATION image, it will reconvert it again! ie: If you change a source picture, at the moment it is not reconverted so the smaller image is actually wrong (out of date).

2) An option to MIRROR? ie: So it goes through all photos in the SOURCE folder and mirrors them to a DESTINATION folder (it can already do this). But then any photos in the DESTINATION folder that are not in the SOURCE folder are removed.

Vlasta (2009-04-22 13:13:24):

1) It should already take modification dates into account. If it does not, it is a bug.
2) I will consider it, but it is a relatively large change and it could be destructive. Maybe some other tool can be used to sync folders?

Unknown author (2009-04-28 02:58:03):

You are simply THE BEST, I am professional but your tools is so good that I totally rely on it. Thanks for developing such a great and handy tool! I recommend it to everyone.

A suggestion: could the resized pictures be placed in a sub folder like <resized> or <resized400>

Vlasta (2009-04-29 09:47:11):

That is possible, but you must use a command line parameter like "-c<ROOT><PATH>resized<SIZE>\<NAME>.jpg"

Great tool! Exactly what I need.

I noticed though that the Modified date or Creation date is not preserved as mentioned in the "What's new in version 3.0" section.

I'm running Vista. Perhaps it's just a bug or am I missing an option?

Here's my command line:
PhotoResize.exe -r -f1920x1080 -q100 -m -i -s "C:\Pictures"

Unknown author (2009-05-11 08:47:18):

I am also not getting the date of the original file being preserved (I'm running v3.5 under XP). My command line:
C:\WinUtils\PhotoResizeP50RUO.exe" "-cD:\Images (shrunk)\<PATH><NAME>.jpg" "D:\Images"

Vlasta (2009-05-11 16:55:46):

I did tests also with the exact setting of both of you and the creation date was preserved as it should. The modification and access dates are changed. I ma sorry, but do not know how to help you.

Unknown author (2009-05-12 22:39:19):

This Tools works great!!!

Is there a way to save images in folders named by the current date. I have an inspection process that needs to have the images by date and it will be more easily reviewed if I can name the saved folders with the date they were uploaded.
ie. c:\inspections\facility1\090512\*.jpg

Vlasta (2009-05-12 23:45:59):

Unfortunately, that is not possible. But maybe there is such a tool somewhere on the internet. I will consider adding it to the next version.

ipelegri6 (2009-05-18 10:33:30):

Great idea!
But... is it available for linux?

ookpic (2009-05-18 19:26:38):

This tool is pretty cool and I'm looking for this exact functionality. I expecially like the right click context menu feature. However I can't get it to work with multiple files??? If I select a single file and right click and select one of the context items I set up it works great! Only if I select multiple files and right click and choose the same context item, it does nothing? I can select multiple do the drag onto app and it works fine however I don't want to have multiple icons on my desktop just for resizing.

Vlasta (2009-05-21 00:06:11):

All the context menu handling is a bit out of the tools domain. It is mostly in Explorer's hands. I'll look into it, but I cannot promise a solution.

NeilF (2009-05-21 10:46:17):

The one issue I seem to be having is when mirroring my photos to smaller versions using eg:- "D:\pictures\PhotoResizeH720Q90RU.exe" -cD:\pictures_small\<PATH><NAME>.jpg

The problem is that you of course do not want to bother reconverting the 99% of pictures you've not changed, hence the "U" attribute. HOWEVER, this means if you amend a source picture, PhotoResize does not re-render the smaller version of it. So the the smaller (mirrored version) will not match the source one.

Ideally, if the date of a source image is newer than the destination image it should NOT be ignored, as it would appear the source image has been modified?

Hope this makes sense, and can be added into this excellent application!

Vlasta (2009-05-23 09:45:58):

It should already work the way as you suggest, but I will verify it.

Unknown author (2009-05-23 19:51:59):

I can verify that it DOES do this... Sorry for wasting your time. Can't understand why I thought it didn't! Anyway! Good stuff!

All I need to do now is write a dos batch script to remove files in the destination folder, that are no longer in the source folder.

ie: You delete some photos from the source directory, so you want them gone from the destination (converted) pictures too...

Sure I can manage that though :-)

NeilF (2009-05-23 19:53:56):

^^ Sorry that last comment was by me - I hadn't logged in though!

Vlasta (2009-05-24 10:58:27):

Good. If you do that script, I am sure, other people will be interested in it too. There were some requests to add this feature to the tool in the past.

mfspam74 (2009-05-24 20:45:31):

Awesome program. Simple, and does exactly what it says it does. Great job. Count me among the folks that would like to see an option which allows for saving into folders with specific dates.

Currently, I manually sort on the Picture Taken On attribute. Then, by looking over the list I group by date and create the desired folders using 'yyyymmdd'. For example, 20090522. Then, I go back and add details to each folder.

The folder creation step would be an awesome timesaver!

Unknown author (2009-05-28 16:42:15):

I created a new folder on my desktop and then placed the folder over the PhotoResize400 icon. When I went back into the folder that I created only about half of the pictures had the -400 after it. The others did not. Why is that? I'm attempting to email a group of pictures to someone and read that I need to resize them. I was going to email this folder once the -400 was after each picture, but this did not happen. Did I do something wrong?

Vlasta (2009-05-30 09:15:29):

The files without -400 are the originals and the ones with -400 are resized.

Unknown author (2009-06-12 03:36:31):

Tyler (2009-08-16 00:23:30):

Quick question: is there any way to use this application to only change image quality (i.e. the -qXX flag) and *not* actually resize? I can't seem to get the batch file to *not* resize (defaults to 400 pixels wide). I suppose I could simply set the width to 10000 pixels, but that seems like the wrong approach.

My parameters (executing via batch file):

PhotoResizeMROE.exe -o -i -q80 D:\Member_Photos

Great little application!

: Tyler

Vlasta (2009-08-16 08:52:36):

Yes, you can do it by "resizing" to 100 percent with PhotoResizeP100.exe

I have a problem with this awesome app, it appears that even if I ask to not recompress it, it seems it does it.
I use a vbs script to launch it and here is the command line for it:
PhotoResize.exe -ctmp_out.jpg -^900 -q100 -n -m -r -s -o tmp_in.jpg

Thank you for your app.

Vlasta (2009-09-12 09:35:42):

I checked it with your settings and it correctly skips files if they are smaller than 900 pixels. Could it be that you are not deleting tmp_out.jpg if you do more images a row?

Unknown author (2009-09-12 16:59:06):

Is there a way to get for instance, a picture of 1590x1067 120dpi resized to 590xX 200dpi all of that in one command line. I can only get this result by doing PhotoResizeW590EO.exe first, then PhotoResizeD200TEO.exe second. No way to get width resized and dpi resolution overwritten in one line

Unknown author (2009-09-13 11:18:47):


The problem is not about skipping files but the pictures quality is degraded even if I use the -q100. Especially in the dark area where not a lot of information is present.
Look at the bottom left corner on the table, the browns are not smooth anymore:
The photo modified with your software
The original photo

Thanks for your help

Vlasta (2009-09-14 09:51:21):

Resizing & setting DPI in one command is currently not possible. But the second run is very fast and only the number in the header is overwritten and nothing else is touched.


-q100 means maximum jpeg compression, but even in this case, there is some loss. Additional loss in dark areas may occur due to gamma correction accuracy. It is a compromise to speed and color accuracy in more brighter areas.

Unknown author (2009-09-15 18:22:54):

Thanks for the explaination

Unknown author (2009-09-15 20:39:19):

Given a command line as such:-
"C:\Program Files\PhotoResize\PhotoResize400.exe" -h1080 -n -m -u -r "-cD:\Pictures_Resized\<PATH><NAME>.JPG" "D:\Pictures"

Is it possible to say, don't bother converting files that say are <200K? ie: It's already small enough size wise, do copy it, but don't resize/re-render it?

PS: A handy tip:-
ROBOCOPY D:\Pictures D:\Pictures_Resized /PURGE /S

That will remove photos from the destination folder that no longer exist in the source folder...

Unknown author (2009-09-16 01:33:37):

Great stuff! Could this be used with P100 option just to resave the images with their original size? Now defining P100 does not do anything. I know it obviously wouldn't be "resizing" anymore, but one could save disc space by defining the compression quality.

Vlasta (2009-09-16 11:26:30):

I am afraid, no file size conditional resizing is available now. Thanks for the Robocopy tip, many people have asked how to do that.


Recompressing with lower quality is possible with name like PhotoResizeP100Q20.exe Just be sure not to use any of the switches that skip smaller files.

Unknown author (2009-09-16 11:28:07):

When doing a large scale resizing of a source directory to a destination directory, where you're in effect mirroring your original (10,000 photos) to smaller versions. The batch command does it, but it will minutes of heavy disc access to go through all the photos only for it to realise nothing (or little) has to be done because 99.9% of the photos have already been processed.

Is there anyway this could be improved? Maybe a specific 'mirror' command so the software knows it's doing such a process resulting in a more efficient/faster processing through the files?

ROBOCOPY can copy/check files in a few seconds, so it appears to be possible?

Unknown author (2009-09-16 21:45:48):

WARNING! The ROBOCOPY top above is WRONG!!!

The command:-
ROBOCOPY D:\Pictures D:\Pictures_Resized /PURGE /S
...will overwrite all destination files from the source ones.

The command should instead be:-
ROBOCOPY D:\Pictures D:\Pictures_Resized /PURGE /S /xo

Sorry for the error in the original! Again! Test before use in anger!

Vlasta (2009-09-17 10:26:22):

Did you use the U letter or -u flag? Even if that is used, the tool still checks timestamps of both files and resizes them again if they differ.

Unknown author (2009-09-17 17:51:35):

Many thanks for the "Recompressing with lower quality" tip! Previously I had the skip switch on, so it did not work :-) PhotoResizeP100Q75 does the trick, and the picture quality is still just fine! I added it to context menu with a title "Resave images".

Vlasta (2009-09-23 11:00:16):

Watermarking is unlikely. You can try PhotoStamp available at http://phototools.wordpress.com/

Or you can try RealWorld Photos http://www.rw-designer.com/photo-editor. It can do customizable batch operations and supports droplet usage mode, but it is not free.


There is no limit, except Windows command line length -> use it on whole folders instead of file.

Awesome tool! It totally solves the problem of clients being unable to rescale images. You can just send them this tool, pre-named to their custom wishes!

One addition would improve the usage for me: being able to generate the new images in the folder next to where the resizer is currently in (dynamicly).

Say I have images in c:\source-images\ and I want my thumbnails to be generated in c:\target-images\. I then put my PhotoResize400.exe in c:\target-images\ and drag my folder c:\source-images\ on it, after which the thumbs will be generated in c:\target-images\.

Vlasta (2009-11-01 12:08:23):

I am afraid that is currently not possible, but you can use the Crop mode to cut the central portion or the Retarget mode, but it will take long and probably not look good on such a large aspect ratio change.

Awesome tool - would be nice if there is a feature which supports defining a set of destination folders that mimic the hierarchy of the source folders rather than have all the resized pictures go into a single folder !

I am able to mimic this outcome currently by creating a copy of the picture folders and picture files and then having the resized photos replace the originals in place.

Vlasta (2009-11-23 11:01:24):

You can do that with the -c switch. Look at the second example in What's new in version 2.0.

Hello, great soft very helpful.
I wonder if it's possible to copy file that the software is not treating. I mean, I wanna take a whole folder and treat it but the -s doesn't copy the file I don't want to resize so my new folder only contain the picture that are resized and not all the picture of my folder. So I've got to copy the one he didn't copy in the new folder to make this new folder complete.
I don't think I can what I'm asking you because I searched a lot but i'm asking anyway.
Thanks a lot for your time. Keep up the good work.

I would like to add a context menu item that re-sizes pictures and adds them to a resized folder under the original folder. I renamed the application PhotoResizer800.exe and then added the following parameters in the create context menu screen:
-o "-c<ROOT>\Resized Pictures\"

No luck so far. Anyway, wicked awesome tool. Thanks so much!

Unknown author (2009-12-24 20:24:43):

I have found that when the word "re-size" is used in relation to photos that it usually refers to "file size" , pixels etc.
Will this program batch resize the actual size of the picture so that I can put 4 or even 6 photos on a page?


Vlasta (2009-12-25 10:09:02):

Regarding the -c flag, you must specify a full template for the path , including a name - check the examples.

Physical file resizing is not directly supported, but if you use something like PhotoResizeD100T.exe it will change the resolution to 100. Though you may have to experiment with the value to get the physical size you want.

Unknown author (2009-12-28 04:02:57):

Many thanks for this great software. It is super-effective to reduce size but keep excellent quality. It is helpful in sharing resized images in emails!

Unknown author (2010-02-01 18:37:12):

Fantastic! This software is awesome !!! I've been using version 2.0 for about one year and now I just got the 4.0 version. Great job, guys !
I also downloaded RWPhoto and RWPaint for evaluation, so far they are great software too. Keeping the idea that you won't need to be heavy and expensive to be good!
Just one final comment: Any chance of having a future version that supports PNG files? Nowadays we must deal with transparency ...

Congratulations, keep the good work!!

wuow go for it thanx raymond

Vlasta (2010-02-02 10:20:58):

I am glad you like it :-). PNG support is unlikely, I want to keep the file size down and the software easy to maintain.

Though, RWPhotos can do that and you can create droplets, so it can still be as simple as dragging and dropping folders/files on a desktop icon to resize or process pictures.

Hi! Great program!

But just a question: Can I select if the produced jpgs are progressive or non-progrssive? Which is default?

And which subsampling is used and is this changable?

Vlasta (2010-02-20 01:32:03):

Always non-progressive (I guess... whichever is the default in libjpeg).

Chroma subsampling is changeable with -x11, -x12, -x21, -x22 switches. 2x2 is default.

Unknown author (2010-02-24 07:50:28):

Wow... Was looking through the different options, advanced settings, the user interface and the image re-targeting algorithm... a lot of thought has gone into it. Truly amazing.

Thanks for keeping it free. :-)

Paul Gregory (2010-02-24 11:49:55):

Nifty program. The A switch is useful, but two further resizing methods would be very useful for products. If I could use this in my ecommerce projects, the saving in user time would warrant a significant donation.

"Whitespace Removal"
Image is first cropped to remove whitespace before resizing begins.

"Whitespace Addition"
Like Frame Size (eg PhotoResizeF400x300.exe) but white space is added (and the image centred) rather than having a smaller height or width.

Here I echo bigbangtech and a couple of other commenters, so there is clearly demand for it.

Vlasta (2010-02-25 11:57:52):

I understand the needs for new resizing modes, but these are a bit trickier than the others, because they require more parameters. A color must be specified to extend the canvas in addition to the target size. Tolerance (it is a .jpg with artifacts) is needed for automatic empty border removal.

I'll see what can be done.

BTW RW Photos can be configured to do this, but it is not freeware and it is a general purpose image processor and hence slower. I can help you design the batch operation for your specific needs.

I'm using the latest version to batch resizing all files in a folder with the following command line: PhotoResize.exe -O -I -W640 "path to the folder\"

Sometimes PhotoResize lefts a few pictures not resized (it makes the resized images with the FileName-W640.jpg filename and seems failed to rename it to the FileName.jpg back).

Could you please check that you properly release source image before you start to rename temp file back?

Vlasta (2010-04-08 12:00:13):

Not easily. First you would have to crop and resample it to given aspect ration and size in pixels and then you would have to set the resolution.

I just love this program! It got so much better in recent updates!
bug? I think that the kilobyte switch has problem dealing with anything over than 400kb. I cannot get PhotoResize to create anything that is even remotely close to the desired file size...

Vlasta (2010-05-06 10:30:46):

400kB is a lot for an image. If the file at the selected compression level and original size has less than 400kB, the tool leaves it at the original size. If you want to see 400kB images, you need a huge source image and/or increase the compression quality.

Unknown author (2010-05-12 16:57:59):

Is this program compatible with Mac OS X?

Unknown author (2010-05-13 13:23:57):

Is it possible to add some sort of progress indicator to the command line window when the program is running? I am resizing a large number of photos using the recursive flag (about 10,000!), but I have no way of knowing how far the tool has got through the process! Thanks.

Vlasta (2010-05-13 13:40:53):

No, that is out of the scope of this tool.

I guess you could use the -o flag with a parameter (for example -oX) to print X for each processed file. With 10000 files and 80 characters per line, you can expect 125 lines full of X. That can help you estimate the progress.

BossTurbo (2010-05-18 22:33:15):

Hi Vlasta,

Will this program work with all 6 cores for the new AMD 6 core processors? I will be using Windows 7 64-bit. I have a 4 core processor now and it works awesome.


Vlasta (2010-05-18 22:40:11):

There should be no problem up to the current Windows limit of 32 processors or cores.

Unknown author (2010-05-29 19:28:53):

Would really like the F otpion, but which also introduced a border.

eg: So PhotoResizeF400x300.exe, but the image is ALWAYS 400x300, but with a black(?) border top/bottom or left/right to retain aspect ratio.

eg: A 900x1200 image would be converted to 225x300 to retain its aspect ratio, and then given black borders left and right to make it 400x300.

Make sense?

A 1200x600 image, would be converted to 400x200, and given black borders top and bottom to make it 400x300.

Vlasta (2010-05-29 22:35:04):

Something like that will be added in future version.

RE: Option to resize photos to a size, maintaining their aspect, and then filling/padding out to match specified size - That would excellent thanks!

Unknown author (2010-05-31 11:21:55):

This is very useful tool for me to change file size and resize images to smaller. Now i have some new restriction to use on images. I need to change size of images that are too small but only the frame and backgroud color.
For example, maximum size 600x600 and minimum 350x350, i have to hold aspect ratio. It sould be square so i have to hold white backgroud for the frame.
Do You plan to add maximum and minimum sizes together?

Vlasta (2010-05-31 15:34:15):

That seems to be a bit out of the scope of this tool. This scenario is a special one and very few people would benefit from it. You can script something like that in RealWorld Photos. I can do such script in less than 5 minutes if you are interested.

Hi, I was wondering which options to use to achieve the following:

I would like to search all subfolders within a main folder for files called folder.jpg then resize each and every file called folder.jpg to a specific size and save the new resized file over the original. Same name i.e. folder.jpg

Vlasta (2010-06-27 14:46:38):

Sadly, you cannot limit the resizing to files called folder.jpg. It will resize all .jpg files found (with R at the end). Scripting maybe...

Unknown author (2010-06-27 14:51:50):

I really like this tool btw, sorry i didnt say that in my previous question.

That would suit my purposes adequately. Which script/additional options would i use to find all .jpg's ending in 'r' within a folder/subfolder structure and resize to specific size then overwrite?

Vlasta (2010-06-27 14:53:08):

The same answer. There are no input filters - it's all or nothing.

But I will consider adding that to the future version.

Unknown author (2010-06-27 14:56:06):

ok, thanks for you assistance. much appreciated

Unknown author (2010-06-27 19:15:20):

What is the exact type of resampling used (bilinear, bicubic, lanczos)?

Vlasta (2010-06-27 19:43:52):

The tool is focused on reducing image size and computes coverage percentage for each pixel, no interpolation is needed in this case. In the rarer case, when image size is increased, bilinear interpolation is used. Gamma correction is taken into account in both cases.

Is there a way to assign both W and H dimension and using W as the longhest ?
I mean, with -^640 I can resize vertical and horizontal images using the longhest dim, but I can't specify the size of the other dimension

Vlasta (2010-06-28 15:00:34):

I am sorry, I do not understand what you want -> examples. If you want to specify the size of both dimensions, you can, but aspect ratio is not kept automatically. There are many resizing modes, some take two dimensions. There is a good chance one of them will do what you need.

Unknown author (2010-06-28 16:39:56):

image1 is 300x100 and image2 is 100x300 and I want to resize them respectively 350x160 and 160x350

if I use the -^350 option, the images will be resized like this: image1=350x117 and image2=117x350 - WRONG size -
if I use the -^350x160 option, the images will be resized like this: image1=350x160 and image2=350x160 - WRONG, image2 became landscape -
if I use the -f350x160 option, the images will be resized like this: image1=350x116 and image2=53x160 - WRONG size -

I hope to be clear about the situation, I can't find an option that can resize both dimension maintaining the landscape/portrait status

Thank you very much

Vlasta (2010-06-28 16:50:52):

Now I understand - this is sadly not possible. Most people are happy with the results -^350 gives as it maintains aspect ratio. I have hard time imagining in what situation it would be needed to change the other dimension to 160 and hence change the aspect ratio. Could you describe your scenario - why you need this behavior? (If I feel such a feature would benefit other people I would consider adding such resizing option.)

Unknown author (2010-06-28 18:12:00):

First of all, the values I used were only there for the example, but I was interested in that function like a workaround in case of wrong aspect ratio of the original images, because the resulting images will be shown in a report page that NEED the right dimensions or it changes it's aspect moving the other elements... in this case is better a distorted image than a distorted report.
The original images are edited by different people, and not all of them knows how to use a computer... so, in the OPTIMAL situation, ALL the images have the right size/aspect ratio, and the -^350 would be great, but I trust the Murphy's Laws about programmers !! :-D

Anyway I'm trying to asking them to name landscape files in a different way so I can filter them.

P.S.: I like very much the photoresize.exe renaming thing !! It's "strange" but very useful !! ;-)

Vlasta (2010-06-28 20:00:39):

OK, I understand that. It is a bit atypical scenario - you need two things at once - different landscape and portrait processing and aspect ratio change. I plan to add a new mode - canvas extension - to the next version. If you are able to separate portraits and landscapes, it would help a bit with the quality.

I also have a paid product ( http://www.rw-designer.com/photo-editor ) that can do this if you can use javascript. It is slower, but also supports drag and drop on icon.

first of all congratulation or this exciting picture tool !

I have spent a lot of time solving the following problem with no efforts:

I have two pictures, one (P1) with a size of 640x480 and one (P2) with 1600x1200. In my batch file I use the following command:

PhotoResize.exe -f1280x1024 -i -m -o -r "C:\Tmp\Test"

P2 is resized to 1280x960 -> OK

No, it always re-encodes the image.

Version 5 is very universal. I like this this tool and i'm using it till version 2. Great work!

How can i use new setting together?

I need to have my pictures maximum 600x600 but larger then 400x400. I have jpgs that can be smaller as source than 400x400 or bigger than 600x600. If it's smaller than 400x400 i need to enlarge canvas with white backgroud and left picture in original dimensions in the middle.
Is it possible to do this in one step?

Vlasta (2010-09-14 23:11:30):

Sadly, that is not possible in one step, not even in multiple steps if you wanted it to be universal. Even if canvas is extended, the picture is resized to fill as much space as possible while maintaining aspect ratio.

Unknown author (2010-09-15 21:49:03):

What a great little app. One addition would be to not process images that are the same resolution as the destination resolution, which is a slight variation on the 'do not process images which are already smaller'.

Eg. I always want to have MP3 album covers at 500x500 pixels. If i drop anything smaller or larger than that, it gets resized. If i drop anything which is already 500x500 pixels (for example, one i've already resized) it gets ignored and isn't processed.


Vlasta (2010-09-15 22:35:40):

I guess something like that should be possible. Maybe simply copying the file if it has the right size would be enough...

Unknown author (2010-09-15 23:27:20):

ah yes, i forgot that some people will be wanting the processed image(s) to end up in a different folder and in this case they would want to see the unprocessed files in that folder too. I always use the 'overwrite originals' option so for me, just not processing the file would be sufficient.

Unknown author (2010-09-20 23:55:13):

Imagemagick, IrfanView and other tools are either buggy or don't walk recursively and replace the original files! After three hours searching, I found your tool! Thanks!

lavajava (2010-09-22 14:32:34):


Superb little tool!... Would it be possible to have the option to monitor a folder / subfolder for any changes somehow, then automatically resize any new pictures appearing in that folder?

The software works perfectly, but everytime I want to scan my pictures folder for new images it has to scan through 100,000+ images! It would be a lot quicker if the software could just run permanently (or as a service) and just process any new ones.

Thanks for a great tool anyway!

Unknown author (2010-09-23 08:36:32):

Wonderful app, but I beleive i found a bug.
I named the app PhotoResize.exe and command line parameters so that I can define the output names and folder.
The bug happens if i use "-r" (to process subfolders) and "-z*_.*" (to only process images ending in "_") the app doesn't process anything in subfolder unless I rename the subfolder so that it's name ends in "_".

I don't think filter for files should filter folders.
Maybe a separate filter for folders?

Thank you, Silvio

Vlasta (2010-09-23 10:33:20):

About the monitoring: neat idea, but probably too ambitions for this king of tool.

The bug...I guess you are right the search for sub-folders and files is shared. I forgot about it.

Unknown author (2010-09-25 17:05:39):

Yes, lt's great and simple to operate. Thx.

Unknown author (2010-09-27 18:44:05):

is it possible for this tool to resize other image formats e.g. TIFF, PNG etc. ?

Great application. Exactly what I was looking for! Thank you!

Unknown author (2010-09-29 21:09:50):

Fantastic. With a bit of batch scripting I now have resizer automatically updating a desktop slide show when new pictures show up in a certain folder.

Unknown author (2010-10-21 09:55:24):


will (2010-10-21 19:08:29):

In addition to resizing the images, is there a way to have your program date stamp the picture? I understand the "M" command but I am hoping that it would be possible to actually see the EXIF info on the pic.

Vlasta (2010-10-21 19:53:00):

That is out of the scope of the tool, but there are tools that can do that. And of, course, there is RealWorld Photos, where you can use the watermarking operation for that.

Si the Dogblogger (2011-03-23 11:40:51):

This is a ripper of a free program.
I have multiple copies scattered through all my photo and image folders.
Anyone downloading this, RTFM ! Read The Manual.
All you have to do is 'rename' the program file. Then drag and drop images onto it for instant resize. Easy Peasy.

My usual file is renamed as "PhotoResizeP75Q75IO.exe".
This means - reduce to Percent 75% of original, at Quality 75%, I=overwrite original file, O=don't wait for the Enter button prompt (makes it a tad quicker).

I then select all the images I want to resize by holding down CTRL and right clicking on all the images I want, then drag onto program file. So easy.

This brings my huge 1Mb pics down to about 110kb. A size suitable for posting in blogs. ;-)

See my post...

Big big thanks for offering this for free.
Ah, I see your PayPal button. I'll buy you a beer.
Cheers. Si 8-)

Unknown author (2011-03-25 09:36:57):

I have been using your photo resizer for some time now. Recently another person asked me about it and I went to your site and saw there was a newer version, so I downloaded it. 5.0 I haven't been able to use it as I keep getting an error message that says It is not a valid Win32.exe application. How can I fix this?

Vlasta (2011-03-25 09:44:23):

Try downloading it again. Make sure you are using the correct version for your Windows.

Unknown author (2011-03-27 13:08:54):

The software freezes with picture 22. No pictures are created anymore. Plus the CPU usage goes up to 100% on all cores, why? Furthermore, I wanted to drop over 500 pictures on the icon and I get silly error messages such as file name too long.

This tool is unfortunately useless for batch conversion :-(. Furthermore, the idea of renaming the tool to change the size of the files is extremely silly. How would I know what options I have if I do not have access to the website? I was hoping for a goot tool, but it turned out to be useless as many others.

Vlasta (2011-03-27 13:23:36):

The limit is on Windows side (it does not allow dropping too many files at once). Drag and drop folder instead of individual files instead.

Hard to guess what went wrong with your picture #22...

Unknown author (2011-05-01 08:51:43):

Thanks. The first download was incomplete at 245KB and I got the same problem others had: Windows complained that it is "not a valid Win32.exe application." I redownloaded and got 305KB and no more problem.

I renamed the file "PhotoResize1600.exe" so i can get 1600x1200 from 3264x2448. When I ran the file, it did not do anything except present me with a box that allows me to set the command name (default: "Resize Picture" and options (default: -o), with buttons "Add to context menu," "Remove all," "Donate," and "Close." I just clicked on "Add to context menu" and used Windows Explorer (I have Windows XP) to locate my pictures. I right-clicked on the folder containing my pictures, and the context menu appeared. There was the "Resize Picture" command and i clicked on it. A DOS box appeared with nothing in it, no text to indicate what is happening. But there were new files on the folder corresponding to my picture files, named filename-1600.jpg, etc. All the 327 3264x2448 pics were converted to 1600x1200 pics in a couple of minutes (well, maybe 3 or 4 or even 5 minutes). I just downloaded the file several minutes ago and have not tried all its options, much less use the command line for it. But it works. A real timesaver. Thanks a lot.

It would be great, if this also could rotate pictures according to EXIF-data. Maybe R after name?

Unknown author (2011-05-21 19:17:47):

This looks awesome, yet I'm getting frustrated b/c I can't seem to get it to do what I think should be a simple task.

Resize all my folder.jpg files that are in sub folders of my movie folder, and keep the original name. I got it to work but I can't seem to get it to only resize the "folder.jpg" files. It wants to resize all the jpegs in all those subfolders. I then noticed the switch -z (specify file to process), so added it but now I can't get it to do anything, or it just doesn't work with -r (subfolders when using -z). In command prompt I only get "Find the latest version, etc." Nothing is being processes, but I know it executed or I wouldn't get the above message.

cmd prompt: photoresizer -w299 -zfolder.jpg -i -c -r -h90

What is wrong with that command, and I even have the photoresizer.exe in the movie folder directory?

I tried PhotoResizeW299ICRG,

Vlasta (2011-05-21 19:30:45):

Unfortunately, in the current version, the filter specified with -z also applies to folder names and so it does not work well with with -r.

The behavior will be changed in the next version to only apply to files.

Unknown author (2011-05-21 19:33:28):

actually that "-h90" is suppose to be "-q90" :-)

Anyway I think it is just by design or a bug, b/c as soon as I remove the -z switch it processes again, but all my jpegs, instead of only the folder.jpgs.

You can try what i did in the batch file...

This software is fantastic really, just wish it worked for my purpose.

If it helps, I'm running windows 7 32bit.


Vlasta (2011-06-23 14:48:50):

Maybe try removing the O and watch the output. There should be an error message at some point.

BTW you do not need to do in-place resizing and then copying - simply let the tool write the result into the desired folder. Also, resizing first to 640x480 and then to 286x286 that has a different aspect ratio will make the result squashed.

The problem is that the new files are put in the same folder with a "1024" at the end. I have to filter them manually. But if they were put into a subfolder of the current folder you could just copy the folder instead of selecting every picture with "1024" at the end.

Vlasta (2011-07-11 12:52:19):

Explore the -c switch...

Unknown author (2011-07-12 22:36:52):

Hi all, have been trying to do the following - drag and drop a file, resize it to fixed width 300 (height not important) and rename it to 'Folder.jpg' and have it drop back into the folder the original file is in - have been trying many things, got to this point - PhotoResizeW300CQ100.exe -cFolder.jpg - does not work - HELP!!!

Vlasta (2011-07-12 23:02:14):

that would not work with drag and drop because you need to use the -c switch (eventually, you can make it work with drag and drop, but you'll need to make a shortcut with the switch)

PhotoResizeW300Q100.exe "-c<ROOT><PATH>Folder.jpg" "the_file_to_process"
Unknown author (2011-07-13 00:46:42):

i can only resize 20 images at a time why?

Unknown author (2011-07-13 00:47:03):

Hi Vlasta, thanks for the fast response. I had created a shortcut and had put the switches into the 'Target' of the shortcut. Unfortunately the code you suggested above does not work as the directory for every one of my image files is different and not explicit. I assume this makes a difference as I added the code above to a shortcut link in the 'Target' box and it does not work as follows: -

PhotoResizeW300Q100.exe "-c<ROOT><PATH>Folder.jpg" "Cover (front).jpg"

Any more suggestions?

Vlasta (2011-07-13 02:11:49):

maybe try a .bat file instead of a shortcut and forward the dropped file with %1

PhotoResizeW300Q100.exe "-c<ROOT><PATH>Folder.jpg" %1

about the 20 file limit - it has been answered couple of times, search the older comments

Unknown author (2011-07-14 23:41:05):

Excellent tool, albeit a little bit exotic on the usage.

I needed to resize all my images to a max of 800x600 for display on my digital photo frame, while keeping proportions and applying a nice anti-aliasing, while leaving smaller images alone.

Using the renaming wizard, I simply renamed the tool PhotoResizeF800x600MCRSOUEQ95.exe, made a shortcut that pointed to a target folder to dump the resized images and voilà, everything turned out perfect.

Unknown author (2011-07-21 14:27:53):

Hi Vlasta, and thanks for you great work with this tool, I have two questions regarding PhotoResize :

1) in command line mode, is there any way for PhotoResize to take the source image filenames from an external file. For instance I'd like to create a file 'imglist.txt' like this one :


Then execute a Photoresize -w400 "-[FLAG]imglist.txt"

2) under which license is distributed PhotoResize ? May it be used in a commercial project ?

Thanks for your great work !

Vlasta (2011-07-28 11:52:37):

1) No, external files are not supported. Only the command line options (you can put multiple files or folders on the command line at once).

2) It is free for any legal purpose.

Thanks for your quick answer Vlasta, it would be a great option to override the command line length limitation discussed several times in comments above. It may also work in drag'n drop mode (if the user drag a .txt file hover the app icon, you know that you have to read jpg filenames from the file). Any chance to see a new "-fromPICLIST.TXT" flag in a near future ?

Another suggestion, for performance it would be great if PhotoResize could resample the same picture to several sizes in one call. For instance to resize a picture AND make a thumbnail in just one call. This could be also made by defining options in an external file...here is my dream :

- create an OPTIONS.TXT file like this :

// web image (full)
-q80 -n -o -w800 "-cC:\path\web\full\<NAME>.jpg"
// web thumbnail (small)
-q50 -n -o -a75x75 "-cC:\path\web\thumbs\<NAME>.jpg"
// web thumbnail (large)
-q50 -n -o -a120x120 "-cC:\path\web\thumbs\<NAME>.jpg"
// ui thumbnail
-q60 -n -o -a150x150 "-cC:\path\ui\<NAME>.jpg"

- create a PICS.TXT file like this


And then call PhotoResize like this :

PhotoResize.exe -paramOPTIONS.TXT -fromPICS.TXT

This would resize each image listed in PICS.TXT with the params specified in OPTIONS.TXT. In this sample it would create 4x3=12 resampled pictures in one call which should be far faster than calling PhotoResize.exe 12 times...

Am I dreaming ?

Again, thanks for your work !

Vlasta (2011-07-29 11:00:57):

I'll consider it, but I want to keep things very simple with this tool. If I am going to do this, it will accept one .txt file that will act as a long command line.

Multiple operations in a single run are supported right now, but there is no speed advantage. Right now, the parameters are processed from left to right, "options" parameters and "source file" parameter can be combined. For example:

PhotoResize.exe -q80 -n -o -w800 "-cC:\path\web\full\<NAME>.jpg" "C:\path1\img1.jpg" "C:\path2\path3\img2.jpg" -q50 -a75x75 "-cC:\path\web\thumbs\<NAME>.jpg" "-cC:\path\web\full\<NAME>.jpg" "C:\path1\img1.jpg" "C:\path2\path3\img2.jpg"

The same could work with the .txt file.

Unknown author (2011-07-29 12:39:27):

Thanks Vlasta, I thought that it would be faster to load the original image once in order to resample it to N different formats. For instance if I do this :

PhotoResize.exe -w800 "mypic.jpg" -w400 "mypic.jpg"

Does the original "mypic.jpg" will be loaded and uncompressed once or twice ?

Is there any chance that you release the sources of your tool one day in order to allow developer like me to enhance it (and release the enhancements under the same license as the one you may choose) ?

Thanks anyway.

Vlasta (2011-07-29 13:47:44):

It is loaded and decompressed twice. I am not sure if the increased speed would be worth the complexity it would introduce - the source code is already pretty complicated. Are you having a speed problem at this moment?

The source code is basically libjpeg+resampling+a load of messy hacks that piled one on the other during the years. I am kind of hesitant to make it publicly available.

Unknown author (2011-07-29 16:56:59):

performance is always an issue when processing many files, and for now it's the fastest command line jpg resizer I have found around...

Anyway, I would greatly appreciate an option to send parameters through a file in order to override the command line length limitation.


Vlasta (2011-07-29 17:13:00):

OK, I'll see what can be done about the speed in general. There may be other areas to explore, like using optimized version of the jpeg codec.

I have a problem resizing images bigger than about 1275kB:
"Error occured while processing: file.jpg"

No problem with smaller images:
"Picture resized: file.jpg"

I use Resizer5.0 + Windows XP (+ 2GB memory :))

Any idea what might be wrong???


Unknown author (2011-08-17 18:05:35):

More investigation: filesize seems to be but is not the real problem. I have images from another source that are bigger and give no problem at all. I'm stuck. There is something in the jpg files that makes Picture Resizer crash but I don't know what.


Vlasta (2011-08-17 20:14:17):

Some unusual .jpgs using the CMYK color space are not supported. Also, sometimes, a file may not be in jpg format despite having the .jpg extension.

Unknown author (2011-08-21 12:31:36):

I have just tried this with a small number of files by putting the files in one folder and dragging the folder to the program icon. It is excellent for my needs, which is for posting photos to a forum. There is one small disadvantage; the converted files being in the same folder as the originals means that I have to be a bit creative with file ordering to be able to select them en bloc to move them or upload them. It would be nice if the converted files were put in a sub-folder of the original folder. Otherwise, great! Thank you. :-)


Vlasta (2011-08-21 14:05:34):

For that you'll have to use the -c switch with a path template and possibly a shortcut or a context menu item to keep the drag and drop functionality.

Unknown author (2011-08-22 13:09:47):

Thanks Vlasta, that was enough to put me on the right track. I used your method for changing the default output folder to one of my choice, as described in "Picture Resizer advanced configuration", using the C suffix and making a shortcut. Having a default output folder separate from the source folder, is sufficient for my needs.


peterli (2011-09-04 02:51:06):

It would be great to enable a popup box with a command line switch. This popup box would allow me to enter a prefix. Then, in conjunction with the -c switch, I could rename my files <PREFIX>_<INDEX>.jpg

I would also be interested in helping develop this.

Unknown author (2011-09-06 02:48:07):

how to save in c:\photos\a.jpg c:\photos\b.jpg c:\photos\c.jpg ?

Vlasta (2011-09-06 10:57:47):

The pop-up box is an interesting idea. Maybe it could pop up when absolutely no parameters are given.

regarding the other comment:
"-cc:\photos\a.jpg" will always save to c:\photos\a.jpg
If you want the tool to automatically name the file a, b, c, that is not possible, but you can use numbers with "c:\photos\<INDEX>.jpg" It will start with 1 for each batch.

Unknown author (2011-09-12 08:00:22):

This program is awesome thanks so much!

GerryS (2011-09-12 23:41:28):

I agree that the popup would be a nice addition.

One question: should the -c option work with a relative path? In my quick tests it did not seem to. A common pattern for me would want the new images to be in a subfolder (named small or resized or 1024) of where the original images are. If it should work I will keep trying.

BTW, I like the program well enough that I just made a small contribution. Keep up the good work.

Vlasta (2011-09-13 00:25:11):

It does not work with relative paths, but you can do what you described with something like "-c<ROOT><PATH>resized/<NAME>.jpg" or "-c<ROOT>resized/<PATH><NAME>.jpg" depending on where should the new folder be created - in the deepest folders or in the top folder that was processed.

I've been using this Photo Resizer for years and never found anything that works better or easier. I'm using Windows Vista and place PhotoResizer in the Quick Launch area where I can drag my images from the file explorer easily. As soon as I release the jpg or group of jpg files I dragged, the DOS windows pops up reporting the resize is complete. When I press Enter as instructed, my resized images appear in the same folder as the originals only much smaller in size. It's great to resize images for webpages so they can load very quickly. Thanks for the most excellent program!

Unknown author (2011-10-25 16:31:28):

hey buddy nice app...:)
is it freeware or Open Source

GoldenGod (2012-01-31 13:04:43):

Hmmm, I probably do something wrong, but here is my problem:
I have picture with size: 384x525 and I want to resize it to 640x480 (max width 640 and max height 480 with keeping aspect ratio, so output image should have size around 341x480).
I name file PhotoResizeF640x480.exe and try to drop image file.
Every time I got "Picture skipped"...
What I'm making wrong?

P.S. Do you plan to add PNG resizing ability? And maybe some more resizing filters (like Lanczos3).

Vlasta (2012-01-31 17:47:58):

Ooops, it is actually a bug - fixed now, please re-download the tool. The x in F640x480 option was incorrectly interpreted as the standalone X option.

Neither PNG nor Lanczos support is likely in the near future. The main task of the tool is shrinking large archives of photographs. Lanczos and other advanced filters are mainly for image magnification, not so useful for shrinking (though I see that you are actually trying to make the pictures larger).

GoldenGod (2012-02-02 09:46:06):

Thank you for fast fix (maybe you should change version number to 6.0.1, to tell users there is newer version).

Now I only need similar app for PNG files. Or even better all-in-one program.

Best regards

Unknown author (2012-02-12 16:12:01):

Super tool - thank-you.
I have come across a few problems whilst trying to resize the canvas using v6.0 32-bit version. I'll try to explain what I have found, but it may not be easy to describe...

1. If you wish to increase the canvas WIDTH, it just goes horribly wrong. It seems to resize the canvas, and start writing the JPEG data at the correct place (the top-left pixel of the original canvas size). But after that, it just writes all the JPEG data using the full width of the new (wider) canvas, instead of writing it within the the central area that would represent the original (narrower) canvas. This happens using both the "name code" method and the command-line.

Increasing the canvas HEIGHT is no problem, presumably because the full width of the resized canvas is the same as the width that the resized image needs to be.

2. When using name codes, Portrait format images seem to be skipped if ever you try to specify both a height and a width, eg. PhotoResize160x120.exe / PhotoResizeF160x120.exe / PhotoResizeA160x120.exe / PhotoResize160x120x9.exe

Landscape images are accepted, and Portrait images are accepted when using the command-line.

Thank-you again for a super tool, and sorry to be the bearer of bad news...

Vlasta (2012-02-12 17:53:29):

Hi Simon, I am not sure I understand what is happening in case #1. Are you using FXXXxYYY to set the max. frame size or AXXXxYYY to crop/extend the canvas or something else?

#2 was fixed about a week ago (re-download the tool) - the X option was wrongly in effect when X was used between image dimension numbers.

Unknown author (2012-02-13 01:15:46):

Hi again,
I am using the -WxHxC command-line option to resize an image and increase its canvas size widthways. For example if a have a 200x200 image and I use the command-line option -150x100xFFFFFF, then it should resize the image to 100x100 and add a 25-wide white strip on each side to give a final image of 150 wide x 100 high.

But this is not what happens, and it's probably easier to just try it and see what happens, than to let me try to describe it!

If I was to use -100x150xFFFFFF (100 and 150 other way round), then it would work perfectly well, with a 25 high strip above and below the resized image.

Sorry about #2, yes I see the comments now...

Cheers again, Simon.

Vlasta (2012-02-13 09:45:13):

Now I see it, it is fixed (please re-download once again), sorry for the trouble. I have bumped up the version number to 6.0.1.

Unknown author (2012-02-13 16:07:29):

Think there is a bug with filenames on UNC paths that have spaces in them - try recreating a similar example and processing the file - doesnt seem to work (""s missing somewhere in file naming?). Great idea leaving flexible renaming to pass params to app.

Vlasta (2012-02-21 18:51:00):

if there is a space or a special character in a parameter, enclose the parameter in double quotes

Unknown author (2012-02-28 11:56:29):

my advice: if you are using 'overwrite the original file' with option i, you must have the access rights on the folder with the pictures.

my question: can i combine 'overwrite' and 'do not wait for enter' as photoresizek10io.exe ?

Unknown author (2012-03-03 18:18:15):

Hi, I have a problem handling square images. Sometimes I need to handle them as landscape images, and othertimes as portrait images. The -if switch seems to control this, but it doesn't seem to work as the description suggests.

The description suggests:
-if X<Y resize portrait
-if Y>=X resize portrait and square
-if Y<X resize landscape
-if X>=Y resize landscape and square

but it seems to do:
-if X<Y resize portrait
-if Y>=X resize portrait
-if Y<X resize landscape and square
-if X>=Y resize landscape and square

ie. It always treats a square image as a landscape image.

Thanks for a great program, it's the best I've come across.

Vlasta (2012-03-03 18:30:52):

You are right, square images are always processed with landscape images. The tool really recognizes only 2 states landscape+square and portrait (equivalent to the filename-option-letters X and Y), which were needed to solve a use case.

The -if syntax is unnecessarily complex for this simple task, but it was designed to allow wider range of conditions in the future (for example X>300). At this moment the tool just looks at the first letter (X or Y) and at the next character (< or >) and makes the decision.

Unknown author (2012-03-03 18:43:23):

Thanks for the fast reply and clarification.

Unknown author (2012-03-08 11:09:50):

@Vlasta - you dont have the option to change how the arguments are passed as you suggest when dragging/dropping files (re: 21feb2012 post) - and these arguments are passed within quotes internally, but I don't think that the image resizer is processing them correctly. Try an example of a UNC path (eg, "\my host\my directory\image 123.jpg") and drop this onto the application. It won't be processed properly. But nice work with your tool - very good implementation.

If I might make another suggestion - when you double click the icon, it would be nice if it itself posts what it perceives as the arguments (the single letters that denote what type of processing). As a few of these aren't obvious what they do. Perhaps also to configure its own file name rather than needing to be reliant on the web page for changing the file name. Again, nice job. Just further suggestions for improvements.

Vlasta (2012-03-08 12:55:58):

OK, I'll do some tests with UNC paths and possibly fix it.

Regarding the default (non-existent) GUI... Yes, I am considering revamping it in the next version and making it much more friendly. All current usage scenarios will be kept intact of course.

Maybe not a bug, but after
Rotate pictures by EXIF orientation tag while resizing (and copy metadata) them with PhotoResize400VM.exe release 6.01,
the resized picture's Oriention tag in EXIF should be set to 1(top-left), isn't it?

Vlasta (2012-08-04 11:10:45):

Well, you are right, but the issue is more complex. Beside the Orientation tag, it would be right to also re-create the thumbnail, update resolution settings and other settings that depend on the X and Y directions. EXIF is a horrible standard (my personal belief is that it was designed so badly on purpose, because even a newbie programmer would design a much better mechanism for storing a couple of name-value pairs) and simply said messing with it is very risky and difficult. And so, I decided it is not worth the trouble. Using V and M together is not recommended.

I tryed to use the PhotoResize400x400x9SO.exe but if the image is smaller than 400 it will skip it. I want to skip the resize but i want at the end to have the canva extended to 400x400.

Is it possible ?

Vlasta (2012-08-24 18:14:19):

No, the canvas can be only extended in 1 direction.

krisannel (2012-08-25 12:31:17):

I have a problem, I have been using resizer for several years, I changed my laptop and dowloaded the latest version of resizer and now he won't appear in my context menu. I click the context buttom buth it doesn't work. :-( My old picture resizer version was 2.0, now I use Win 7 and picture resizer 6.0.
Can anyone give me a tip? Thanks!

Vlasta (2012-08-25 17:52:53):

On my own Win7, it works as expected. Are you sure you have clicked the button for adding the commands to context menu and did not move the tool afterwards?

Unknown author (2012-08-27 02:59:44):

fow windows 7 try image-scale.com
that is free as well and works perfectly on vista/windows7

Unknown author (2012-08-29 11:07:31):

Hi Vlasta , can your tool be used without renaming the original file?

Vlasta (2012-09-01 18:19:22):

Yes, but that means overwriting the original - be careful with that...

Unknown author (2012-09-05 10:10:43):

Very cool Tool :-D Would be nice when other formats like png work too.

Unknown author (2012-09-06 16:17:37):

Hy Vlasta,

In a DOS cession, this command doesn't work

PhotoResize640.exe -o "-cC\temp\photo1.jpg" "C:\temp\photo.jpg"

No "photo1.jpg"

Without the -c option it generates a photo-640.jpg file.

What do I wrong.

Vlasta (2012-09-06 17:38:06):

perhaps you have forgotten the : between C and \ ?

Unknown author (2012-09-07 09:33:24):

Hy Vlata,

I retried this morning, and it’s working.
I don't understand what I did wrong yesterday, because I tried more than 50 times with or without the compete path ...

Thank-you for your help

Hy Vlata

I have a stange sesult If I use the result of a converted picture for a second conversion.

First convertion, I get a picture 640X480 pixel X  96 DPI

If I reuse this picture with PhotoResize640.exe, I get a picture 640X480 pixel, but 1DPI
Is this a bug ?

Vlasta (2012-09-10 10:24:17):

It could be a bug, but I cannot reproduce it. Are there any other special conditions?

Unknown author (2012-09-10 11:32:52):

FYI It did not work for me with a batch of jpeg files. Worked only with a single jpeg and the loss in quality was very bad. There appears to be no control over level of resizing. Thanks anyway

Unknown author (2012-10-20 18:44:39):

Cool tool! Is there a way to set the tool not to resize the picture, just process it? Then it can be used for bulk image quality change resulting in lower occupied space...

Unknown author (2012-12-03 18:48:00):

Took a few minutes to figure out how to use this tool but well worth it. Ive been looking everywhere for an image batch reizer with the power of this tool. I was able to resize all of my cover art that was over a certain size to the size I wanted with one step, and not touch anything that was already that size or smaller. Absolutely perfect!!!

How do you uninstall and then start over?
Jim N1NH@tds.net
Email me???

Vlasta (2013-01-12 20:52:49):

There is no skin folder - that must be from a different tool. Conversion may fail, if the source image is not a standard .jpg file of if the tool does not have write permissions in the destination folder.

Thank you for this great program. I've been using it since Windows XP and at first wasn't able to find it again when I migrated to Windows 7. All those other programs cluttered the google search results...

I'm glad I found it again. It works in Windows 7 via drag and drop, but it doesn't show in the context menu :-(. Do you have a hint what I can do?

Unknown author (2013-03-26 12:38:06):

For Windows 7-64 bit, which file should be run?

Any of them.

Unknown author (2013-06-06 22:06:40):

Awevome - resizing graphics for web - really fast, (sent it to 2 friends)

Would be ever possible to produce multiple sizes from one picture? (or I didn' catch it)
something as: PhotoResizeW160W530W1024NOQ85.exe

Vlasta (2013-06-07 00:59:28):

You cannot do that directly, but it is possible by using command line switches or better yet by making several copies of PhotoResizer and calling them from a .bat file with the same file parameter.

Unknown author (2013-06-19 11:40:45):

When will be available version for Win 7-64bit?

Vlasta (2013-06-19 11:46:46):

There is one. Look above. But there is no real point in using it. The 32bit version works fine on both 32bit and 64bit Windows.

Unknown author (2013-06-22 17:52:39):

This software makes resizing pictures so fast and simple. Each member of my family have it on their desktop now. Your work is very much appreciated, thank you :-)

Unknown author (2013-06-23 08:16:31):

This is truly fantastic software. I need to process a large group of folders that all have folders with in each other. Is there a way to have the software create a new folder in each of these folders, containing only the resized photos that were within their respective directories?

Vlasta (2013-06-23 09:03:19):

You can do that with the -c switch (something like "-c<ROOT><PATH>resized\<NAME>.jpg") Keep the double quotes and you'll also likely need the -r switch to process all subfolders. Be aware that you can only run the operation once. If you run it second time, it will process the files in the newly created folders. Using the skip smaller option may help though.

Unknown author (2013-07-01 20:33:54):

Awesome software dude! Thank you whole heartedly for this fantastic tool. I regularly use to resize photos for my own use as well as for my newspaper site.

This is absolutely brilliant software! I kinda freaked out a little today when it took me a while to find the site again. Hah, that will teach me to NOT make a note of it before doing a factory reset on my puter, won't it. Huge sigh of relief when I found the 'right' software again.
Huge thankyou to the creator for this amazing piece of software. :-D :-D

Unknown author (2013-07-19 04:18:34):

LOVE it!

Unknown author (2013-07-20 17:30:39):

some sites limit size of the submissions to 500K or some of max size. would it you give the resolution 1200X800 and and file size and it make the highest quality picture possible at that size?

Vlasta (2013-07-20 20:32:36):

I am afraid that is impossible to do with current Picture Resizer. You can only set the file size in kB and quality and it will find the right size in pixels. But, if your goat is 1200x800 and 500kB, it is likely that you can just resize to 1200x800 using a high quality setting. The resulting file is likely to be smaller than 500kB.

Unknown author (2013-08-03 10:31:08):


I have a problem with the -z option.

This Works:
PhotoResize.exe -o -^200 "-c<ROOT>pictures\<NAME>.jpg" 0001.jpg

This Dont:
PhotoResize.exe -o -^200 "-c<ROOT>pictures\<NAME>.jpg" "-z*.jpg"

Can You help me??
Thanks for the App!!!

Vlasta (2013-08-03 10:35:18):

-z only specifies a condition, you still must give it file(s) or folder(s) to process.

Unknown author (2013-08-03 10:49:35):

Thanks for your fast answer!!!

Ok, you are right, Works if I put a path.

Can you put an example for the current folder??

I tried this with no success:
PhotoResize.exe -o -^200 "-c<ROOT>pictures\<NAME>.jpg" -z*.jpg "<ROOT>"

Vlasta (2013-08-03 10:58:35):

You can use . for current folder. (But make sure you understand how current folder works in Windows - it is not always the folder, where the .exe is located.)

Unknown author (2013-08-03 11:04:47):

I know, thanks for the advice.

Ahoj, mám problem se syntaxi pro příkazovy řadek.

po přetažení obrazku na ikonu vše funguje bezvadne.

PhotoResizeH1500NICSOUG -o C:\PohodaImportExport\images\
V teto syntaxi to však už nefunguje.

Diky za radu.

Vlasta (2013-09-16 15:03:50):

Nevidim tam zadny zjevny problem, asi za tim bude nejaka drobnost. -o neni treba, kdyz je tam O v nazvu, to .exe by tam mohlo zustat, slozka by mohla byt v uvozovkach...

Unknown author (2013-09-16 19:34:32):

Diky za radu - již jsem to zprovoznil

V tomto tvaru to ji6 funguje
PhotoResizeH1500NICSOUGR -o C:\PohodaImportExport\images\tmp
- přidal jsem volbu i podadresaře.

Problém však nastava s win. nazvy souborů - ty jsou pro PhotoResize "neviditelné"
a preskočí je :-(
např. Název souboru.jpg; nazev_souboru.jpg a pod.

Lze to nějak řešit?
Diky za radu.

Tak vyřešeno

S timto nastavením:
PhotoResizeH1500NICSOUGR "C:\PohodaImportExport\images\tmp"

Jsou viditělné i soubory jako tento:
Název 413016-1 front.jpg

Parada - diky.

Unknown author (2013-09-17 16:29:11):

Ještě jeden dotaz.
Mam trochu potíže s dosovskou syntaxi dlouhych názvů adresařu.
proto mě napadlo varianta, že by PhoteResizer ležel přímo v adresáři, kde jsou fotky.

Jak tuto variantu zapsat do příkazového řádku?

Diky za radu.

Vlasta (2013-09-17 17:13:44):

Kdyz je nazev slozky, ktera ma v nazvu mezery, v uvozovkach, tak by to melo fungovat. Jinak se da pouzit . jako oznaceni aktivniho adresare, ale to nemusi vzdy byt adresar, ve kterem je spustene .exe, takze pozor na to.

Unknown author (2013-09-17 20:28:09):

Hotovo - teda skoro :-(

Problem s adresařem vyřešen

cd Složka s obrazky
c:\...\PhotoResizeH1500NICSOUGR "."

Nastal ale druhy problem:
Lze nastavit PhotoResize tak, aby menši obrazky než H=1500 nepřeskočil, ale aby odstranik EXIF, provedl doostreni a zmenil kvalitu na např 75% ?
A současně obrazky nezvětšoval?

Great tool for batch converting. I use it this set:
1600vio.exe or 800vio.exe
It does exactly what I want - rotate (due to exif data), resize and does not ask for action.
The only problem I met is that I can NOT open converted JPGs in basic Windows Photo Gallery Tool. I do not know exact name of this application, but it says something like this: "Application can not open this picture, cause file is broken, damaged or too big". But I know - files are OK, cause I can open it in Gimp, PS, even in Paint.

BR, Adam

Unknown author (2014-05-21 21:45:24):

Rename 1600vio.exe to another name and back to 1600vio.exe solved problem. I took .exe from one computer to another and maybe it lost something. Renaming returned full functionality.
Lets say it again - good piece of software.

You can use:

PhotoResizeK25.exe "-cC:\resized\<PATH><NAME>.jpg" "C:\uncompressed"

-o can be used to skip waiting for enter; -o with additional options only affects what is sent to the console window

there is incompatible option between -d and -r ?

The tool is fantastic and I've been using it for years. I recently downloaded 6.0. One problem has always existed though, some pictures do not produce a thumbnail and the program does not return an error when run in Windows Shell as part of an ASP page. This is only sometimes. It always works on the command line. If I crop the picture using Thumbs Plus even by 1% and resave it, it'll always work. If I crop the picture using something like IrfanView and resave it, it doesn't make a difference. ThumbsPlus (an older program) must be modifying the original picture in a way that PhotoResize likes whereas IrfanView is not. So the two problems are that it doesn't work on some files and second, it doesn't report an error code even though no thumbnail is produced. Thanks for any help!


Vlasta (2014-07-08 22:04:02):

The tool was built for batch processing of multiple files and only reports errors for individual files. It always returns 0 unless there is an error in the parameters it is given. You may be able to analyze the output of the tool and try to find an "error" string in it. But you cannot use the -o parameter if you want the output and in that case the tool waits for Enter key (so that the user can read the processing report). You can suppress that by sending a file with a newline in it on its standard input: PhotoResize.exe source.jpg <file_with_newline.txt

Or you can simpley check if the thumbnail file was created.

Thanks for responding. I understand why I'm not getting an error code but I don't understand why it is not working. Below is a typical command line:

c:\Automation\PhotoResizeH60MOE "C:\Chronicle\Level3\2013\2013-04\130401091200-TOd-{Friends,Public,!3}Daniel texting me from Swiss town of Basel.jpg"

If I paste this into a CMD box, it works. If I run it in a WScript.Shell, it won't work unless I modify the source picture first. Thoughts? I don't think the command line is too long. Maybe the shell is running out of memory? I'm trying to imagine what the problem is. (Standard out tells me nothing.) Thanks.


Vlasta (2014-07-08 23:38:33):

Sorry, I have no idea.

Unknown author (2014-07-08 23:55:37):

So the basic idea is that if program encounters any issue with the source file, it quits or goes onto the next picture?


Vlasta (2014-07-09 08:02:21):

It continues with the next picture.

Just simple and amazing...Less Is More!!!

Unknown author (2014-07-31 21:23:45):

great tool but I'm running into an issue. Whenever i try to save to another folder the image is always created in the same directory. Below is what i am using. Can you steer me in the right direction

photoresize160.exe -o "c:\102755_09.jpg" "-cC:\images\<name>.jpg"


photoresize160.exe -o "c:\102755_09.jpg" "-cC:\images\102755_09.jpg"

Vlasta (2014-07-31 22:07:15):

You need to put the source image at the end. Only parameters before the source file(s)/folder(s) have any effect on it.

A great little utility but I think I encountered a small bug.

Using exe renamed to PhotoResize1280.exe I attempted to pass parameters -o -i -h but then found that it was the Height rather than the length that was being resized. Seems H is used twice: once for Height and secondly for High resolution.

Worked around this by renaming the exe to include all the parameters.

Vlasta (2014-09-06 16:53:37):

-h as command line parameter must be used with a number, for example -h1280
when using H in the filename, its position matters, PhotoResizeH1280.exe will resize to height of 1280 pixels, PhotoResize1280H.exe will resize the longer side to 1280 and use high quality for compression (you can of course use both)

Vlasta (2014-09-16 12:15:06):

So, what's wrong with the picture? Maybe it is from Photoshop in CMYK?

Unknown author (2014-09-19 11:37:28):

Great tool. I like it very much.

Unknown author (2014-09-29 21:17:17):

I use this utility all the time. Works great! Only issue is occasionally it'll spit out "Error occurred while processing". My buddy told me it may be due to a jpg being created/saved in CMYK mode instead of as RGB. Wish there was a way to know for sure.

Vlasta (2014-09-29 21:25:25):

Right-click on the image in Windows and select Properties and then "Details" tab and look for "Bit depth" line. If it says 32bit, it is a CMYK jpeg. 24bit is normal RGB and 8bit is grayscale.

Unknown author (2014-09-29 21:26:07):

Loveit. Just can't figure out how to make thumbnails without having to rename them the way I want afterwards. For instance, PhotoResize100.exe will create a thumbnail of abc.jpg and name it abc-100.jpg. I would rather it rename it tn-abc.jpg instead, so I have to go in afterwards and rename all the thumbnails.

Vlasta (2014-09-29 21:30:25):

You can do that with

PhotoResize100.exe "-c<ROOT><PATH>tn-<NAME>.jpg" folder_to_process

If you want to run it with the command line parameter via drag and drop, you'll need to create a shortcut or a .bat file.

RE: "Right-click on the image in Windows and select Properties and then "Details" tab and look for "Bit depth" line. If it says 32bit, it is a CMYK jpeg. 24bit is normal RGB and 8bit is grayscale."

Bit Depth for a problem image is 24. But, it also lists creation software as "Adobe Photoshop CS6 (Macintosh)" and Color Representation as "Uncalibrated", so maybe that is the problem?

Vlasta (2014-09-29 21:35:11):

Not sure, another possibility is that it may not actually be a jpg file, just some other image format with incorrect extension. I can look at it if you send it to info@rw-designer.com

Unknown author (2014-10-02 13:25:21):

I have a 4000x3000 300dpi photo from a camera and want 2000x1500 200dpi output. I used PhotoResize2000SEOD200.exe but that resizes to 2000x1500 OK but the dpi is then 72dpi? I seem to only get the dpi to work if I do not specify the image size ( PhotoResizeSEOD200.exe ). I have used Irfanview to do this in the past but I like the PhotoResizer right click image/folder option as it's easier (if that dpi will work).

Vlasta (2014-10-02 13:38:34):

You can only do that in 2 steps. The second PhotoResizeOD200T.exe will be extra fast as it only changes the DPI value and does not re-compress the image.

The reason behind that is that tool tries to always maintain physical size of the picture when it changes the pixel density. (BTW is there a particular reason why you care about the DPI value?)

Unknown author (2014-10-03 10:34:48):

Quick answer and thanks for that, 1 step would have been nice but I can live with 2 as it is still easier than IrfanView. This is for a couple of non technical end users. They take images with a large megapixel camera and then put those in Word which takes up lots of space (one user yesterday got to a 600mb Word file and it died!). I want to allow them to resize the images to 2000px with 200dpi which is about the width of A4 and as big as they will ever print. Word will show an image at it's printed width, so a 400px 200dpi will show as ~5cm wide where as if it was 400px and 72dpi it shows as ~10.5cm wide - so it saves them having to resize in Word. If that makes sense?

This is really a good little tool (but tricky to find when I was searching for something like this) as I find most users really struggle with image resizing and Right Click, Resize makes it easy for them. Will send something over if I can persuade them to use it :-)

Useful features: Being able to add / remove to the Context menu from the commandline (with description) so that you can supply a CMD file with everything in for a non tech user to add to their PC.

More complicated, but a watched folder that images are automatically resized if placed within (then probably moved to a Done folder?) That would be useful running as a service on a server so nothing has to go on the PC!

fantastic tool!! thank you so much for this!!
I'd like to ask for something useful, please. can you make it so that instead of overwriting it sends the original to the recycle bin and keeps the file name for the resized version? that would be fanastic since I might still need the original size of the file but at the end of the day I can just clear the recycle bin.
thank you again for a fantastic tool! I use it every day!

Vlasta (2014-10-11 16:12:25):

Thanks for the exhaustive explanation Rob, maybe it will be worth the time to allow changing both in one step.

And using Recycle Bin is an interesting idea, I'll think about it.

gmon750 (2014-10-15 00:26:16):

First time poster here, but long-time user. :-)

Is there a method/switch to convert CMYK .jpg files to RGB? More specifically, the CMYK .jpg files coming from newer cameras are 32-bit, and PhotoResize.exe doesn't seem to recognize 32-bit files. If I photoshop the image to 24 bit/RGB, then the utility works fine.

Can someone assist?

That being said, this is a great package! Simple and clean! I wish more utilities were like yours!

Unknown author (2014-11-05 20:54:50):

This is pretty cool! But, what about Bmp files? is there a way to do the same with that kind of files?

Even that, this app still being so usefull!!

Unknown author (2014-11-08 17:59:30):

this is a wonderful program, among all programs to compress pictures this is certainly the best, you can choose from many many options and most importantly you can choose the size in KB of the compressed files, which is not present in all the programs I've tried up to now!!
