Minhs Free PhotoResizer is a very simple utility that allows you to batch-resize digital photos. You simply indicate your maximum width or height in pixels and drag and drop your images (or folder containing images) onto the window.

Minhs Free PhotoResizer will then batch-resize all images into a subfolder. It can't get any easier than that. Shell extensions provide the ability to resize directly from Windows Explorer. You can also optionally skip resizing pictures that are already smaller than the desired size. The utility retains EXIF meta-data tags in digital photos and supports JPG/PNG/Bitmap and GIF files

The license of this software is Freeware, you can free download and free use this image resizer software.
