About The Resizer

I made this free resizer because I needed a free app that would easily resize images in bulk (all at once). I looked around for an app like this and found some good ones but once the trial was over, you had to pay to use them. This one is 100% free and it is now here so you can use it as well.

This is how the application looks like:

Features You Must Try

If you’ve used the resizer for a while, or if it’s your first time, you really want to try dragging-and-dropping your images into the Resizer’s window (see Figure 1 below) and using the “Send To” menu (Figure 2) to send the images you wish to resize with the resizer.

There is a known problem with the “Send To” feature, look further down the page for more information.

System Requirements

This application needs the .NET Framework 2.0 to run. If you’re using Windows, it’s you already have it on your computer. If you don’t, my installer will automatically get it off the Microsoft website.

If you’re not using Windows, it will be hard to get my app working. Mostly because it’s hard to get the .NET Framework 2.0 working on another OS that’s not Windows. I have personally never tried to do this.

Known Issue

If you send a lot of files (more than about 15) to the “Send To” menu item, you
get an error window that says: “Windows cannot access the specified device, path,
or file. You may not have the appropriate permissions to access the item.”

After digging around the web I learned that the cause of this problem is that if
you’re sending multiple files, the aggregate length of the full paths and names
for all of those files must be less than 2048 characters.

To work arround this problem I’d have to write a shell extension (in plain English:
Some code that will be run by Windows Explorer) to override the way multiple files
are sent to the Resizer’s executable.

If someone is an expert at this I could use some assistance as I have not implemented
many Win32 interfaces with C#. I do want to do it the .NET way. There are several
pages that say that you should “never” write shell extensions with .NET because
if the user doesn’t have the .NET Framework installed, you can make other applications
crash. Note that this is not an issue in my case since I know that all the users
of my resizer will have the .NET Framework 2.0 on their computer. If they ever uninstall
my resizer, I will make sure the shell extension is removed from their computer
so if in the future they wish to uninstall the .NET Framework they could do it and
nothing would break.

More details can be found here:

  • Here, I found someone that experienced the same problem and knew what
    it was. He’s also hinting which Win32 interfaces I have to implement: IDropTarget
    and IPersistFile::Load()
  • In this link, Dino Esposito (who by the way ROCKS!), explains how to add a context menu to Windows Explorer. This is a feasible workaround for my problem. I say workaround because what I would really want is to use the SendTo menu like the “Compressed (zipped) folder” menu item does it.

    • Hi Carlo, thanks for the offer. But I actually stopped development on this app a long time ago. I just have it available on my website for people that would benefit from it as-is.

  1. I really want to thank you as this App. has helped me so much in starting and maintaining my new Business… All I can Say is Thank You. I hope everything in your life goes well. You Rock…David

  2. Your application is great, it helps me so much. I used to spent hours changing the size of many pictures, now I do it very fast! THANK YOU!

  3. Hello,

    Just like to thank you. So great app. Very useful for multiple image resizing. Thanks a lot.

    • This is awesome! I still use it as well. I think one day something like this will be included in the Windows OS, but until then, my app will continue to be used.

      • You would think so. I use it mostly for my blog and social media. I don’t mind large images from my camera for personal use, but I hate being a bandwith hog. Cheers.

  4. Though you have stopped work on this app, it is still very useful. I just wanted to pass on my word of Thanks for your efforts. Should you ever feel like doing some more work on it, I’d love to have the opportunity to suggest changes (as I’m sure your other loyal followers would as well).

    Best Regards,

  5. Hey Pedro – I’ve been using the PLISKA resizer since the good ole days at Northface/Neumont. Just used it today because I had a whole bunch of pictures that needed resized. Worked great in Windows 8.1!


    • Yeah, it still works! Not sure how since I haven’t touched the code in at least 5 years, hahaha. I’m glad it helped you and it was nice to hear from you again. I hope you’re doing awesome!

  6. Muchas gracias ¡¡ se necesitan mas personas como usted para hacer un mundo mejor y que todo deje de ser solo un negocio ¡¡ un abrazo desde Perú
