Resize images quickly with Image Resizer (Powertoy Clone for Windows)

Up until now whenever I wanted to resize an image I would open up Paint.NET, load the image I want to resize, save it, and go. Yes I know – not a very clever or efficient method to resize images. However I have been using the Paint.NET method because I am, afterall, a creature of habit and it has been convenient for me. Today, however, I plan on breaking the old habits and switching over to Image Resizer; and you will decide to do the same by the end of this post if I do my job properly.

Image Resizer is a program that allows users to resize images very easily; it adds a “Resize Pictures” option in the right-click context menu which users can use whenever they want to resize images:


“Reize Pictures” brings up a small window where users are allowed to select what size they want to resize the image to:


As you can see from the screenshot, there are four predefined sizes to use and users can input custom sizes if they please. The image that is created keeps the same name and same format as the original image except the new image adds a “(Small)”, “(Medium)”, “(Large)”, “(WinCE)”, and “(Custom)” respectively to the end of the name.

The cool thing about Image Resizer is it keeps the size ratio of your image; it will resize your image so the height/width ratio is as close as the original image as possible. In other words, if your image is a 400×200 image and you opt to resize it to the small 640×480 size, the new image will be 640×320 instead of being exactly 640×480; or if you have a 662×527 image and you opt to resize it to the small 640×480 size, the new image will be 602×480 instead of being exactly 640×480. This way, the image will not look weird and messed up.

Other great things about Image Resizer are:

  • Users can resize multiple images at once; just select multiple images before right clicking.
  • There is an option to make images smaller but not larger.
  • The original images can be resized instead of creating a whole new image.
  • Image Resizer works fairly quickly.
  • Image Resizer is open source.

Image Resizer is definitely a very handy tool but there are two areas where I believe Image Resizer can improve:

  • Whenever a user runs Image Resizer, it always starts off in “basic” mode:


This “basic” mode is nice if a user only wants to make use of the four default sizes. However if a user wants to use a custom size, or access any of the other options, he/she will have to click the “Advanced >>” button every time. Having to hit the “Advanced >>” button every time can get rather annoying. It would be better if the developer either got rid of both basic and advanced modes and consolidate it all into one single mode (because frankly there isn’t that much of a difference between the two modes) or make it so the Image Resizer window starts off in the mode it was left in when last used.

  • There is one feature I would like to see added in Image Resizer and that is the ability to resize images based on percentage rather than fixed pixel sizes. Hopefully the developer can incorporate this in the future.

    Interesting, and probably worth checking out at the least. I’ve been using the online image re-size program ImageIris myself.

    It processes photos with HD algorithms so you get a sharper image quality and has options to remove the Noise or even adjust the Focus of a photo (both minimalistic but helpful in their limits). Percentage based re-size up to 200%, it does tell you what the pixel size will be in the end product, but you can save the image and re-upload it to process again.

    I have two real problems with this online program though. 1) The control for setting the percentage isn’t fine enough. Your chance of being able to set it for exactly 171%, for example, is almost non-existent, you’ll get close easily but not right on it without a lot of patience and a very steady hand. 2) You can’t manually enter a name for the new file. By default it adds Imageiris – in front of the existing file name for the saved file. Typing in any other name causes the save to glitch. You can click on an existing file name to save it as that, but that replaces the original file so it’s extremely annoying.

    While I don’t personally consider it a problem, I should also note that it only enlarges photos. There is no option for reducing sizes. This makes it more limited than todays offering.

    Only been following your site for a few days and enjoy reading your postings, thanks. As for this item, well…. neither of the download links actually gets one to a program to download. Never mind though, I have a better (I think) suggestion. I use “FILEminimizer Pictures” from Balesio:

    As a free for home use of a commercial product there are a few limitations at the margins which are easy to get used to but the actual program works very well. The clincher for me is the setting “allow image to be resized” which can be DISABLED. Call me old (fashioned) but whether on my monitor or 60″ HDTV I like to see my pictures full size and not some little postage stamp (remember those) sized glasses requiring image which only uses a small part of the screen. Using this program I get an 81% reduction in file size, eg. 5394kb to 1007kb on a pic I just checked, with no perceived reduction in viewing quality. Emailing these smaller sized pics is also easy. Check it out.

    In the next release, the tool will actually remember the last settings used and have them entered by default when it runs (expanding to advanced mode if needed). That was my biggest annoyance too with the original one. :P

    Resize units are also on my todo list..

    Sorry Ashraf, but I don’t get all this fuss about an image resizer software… Practically all image editor software has this capability. I’ve been using Irfan View for about a decade and love it (has % resize and sharper resample) and I’m sure you know it.

    But the VSO Image Resize @József is a total different approach using mathematical algorithm to manipulate and improve the resultant image.

    Congrats for your great work, as always.

    @bill: You are welcome.

    @József: VSO Image Resizer rings a bell. I believe either I have read about it in the past or used it. I will be sure to check it out again – thanks!

    @Bonnie Domeny: Interesting. I knew about Fookes’ notepad software but not about their thumbnail one. I will be sure to check it out – thanks!

    @Pete: Thanks for letting us know. Everyone has their preferences =).

    @Brice Lambson: Thank you for the very handy software. I do hope in the future, though, you can address the two issues I mention above (I just thought of them so I just added them – they weren’t there when you originally read this post).
