How to Change Image Size Quickly in Windows 10

Resizing images and screenshots is part of my daily work. I like it if I can reduce even milliseconds of time in resizing the pictures. Recently, I met the newly released Microsoft PowerToys. This allows you to quickly resize the image with just a right click and there is no loss of quality. Let’s see how to use it.

How to Change Image Size Quickly in Windows 10

Step 1: To get started, first, we need to install Microsoft PowerToys. It contains various useful tools, one of which is Image Resizer, which we will use this article.

For those who don’t know, Microsoft PowerToys is an additional utility for Windows 10 power users, which means they are not a genuine part of Windows 10 and you have installed it from GitHub.


Step 2: After you install Windows PowerToys, right-click on one of the images and you will have a new option called “Resize image“. Click on it and you will get the Image Resizer pop-up.


Step 3: From the pop-up, you can choose a predetermined size value or even enter a special value. In addition, this also gives you the option to enter special values in Inch, Centimeter, or even Percentage. Leave all the others as defaults.


If you enter a custom value, just enter the width or height. Image Resizer can automatically fill in other dimensions. For example, we upload images to TechWiser with a 675-pixel width. Therefore, I simply enter the width and let the height be filled in automatically.

Step 4: Image Resizer doesn’t overwrite the original file. This makes duplicate files with the same name processed by name size settings. Resizing is really lossless (if you reduce the dimensions).

Image Resizer also allows you to resize images. I use it mostly to resize all images in one folder at a time. To do that, just select all the images, right click and click “Resize image“. The process in front is identical to the steps mentioned above.

If you frequently resize images like me, Image Resizer also gives you the option to edit predefined templates. To do this, go to the tray icon in the lower right corner. On the tray icon, right click on the PowerToys icon and click “Settings“.


In the PowerMenu settings, navigate to the Image Resizer tab. Here, you will see 4 options of resizing default images – Small, Medium, Large, Phone. You can change values according to your needs, delete, or even add dimensions.

Furthermore, if you scroll down, it provides encoding options. In case, Image Resizer doesn’t support the file format that you resized, this will change it to JPEG. This is known as “Fallback encoder”. Next, you have the PNG interlacing and TIFF compression options. If these words sound new to you, just leave them as the default.

Other Alternatives

Microsoft Image Resizer is based on Brice Lambson’s open-source “ImageResizer” tool. This tool has been turned off now and all development has been transferred to Microsoft PowerToys. Similarly, there are other applications such as Image Resizing. This also allows you to resize the image, but the approach is slightly different. You have to right click on the image and choose “Share”> “Resize Image“.

You can also try the popular ImageMagick command line tool. It can quickly batch resize images, compress, and convert images.
