Image Resizer for Windows is a well built little app that lets you resize one or more selected image files directly from within Windows Explorer via the secondary context (right click) menu. The app was designed to be a replacement for Microsoft XP's Image Resizer Powertoy.
Image Resizer for Windows gives users an easy and quick way to resize images within a single click. With it you can conveniently resize one or more selected pictures via the context menu, without the need to open another, third party image editor. It operates as a Windows shell extension, therefore all you need to do is select the photo or photos you want to modify. Next, a dialog window will appear that offers numerous resizing alternatives. Aside from the default sizes (small, medium, large) Image Resizer for Windows allows you to set custom sizes using pixels, percentages, centimeters, or even inches!
Overall, Image Resizer for Windows is lightweight and easy to install and use. It is a great alternative to opening the image in another application. It is a great tool for those who need to resize or batch resize images on a regular basis, as it works with all common image formats.
