FastStone Photo Resizer is an image converter and renaming tool that allows you to process photos in bulk. It is perfect for users who need to handle large numbers of files at once—for example, if you have many photos in BMP format, you can convert them all to JPEG with a single click to save space. You can also add captions or dates, flip images, or adjust colors quickly and easily.
