batchDPI

batchDPI can set all pictures in a folder to a uniform DPI of your choice, no matter where they were downloaded or input from or what they were edited with.

The program allows you to batch-change the DPI of thousands of pictures with a few simple clicks. The tool will copy (not replace) your photos to ensure the safety of your originals. A special destination folder protects your original files from overwriting. The supported formats are PNG, JPG, and JPEG.
