PixCompare

PixCompare will compare picture files to search for duplicates or similar pictures in a large collection of picture files. It works on JPEG, PNG, GIF, and RAW files. (Most Raw formats supported note that loading raw files will take much longer than the other formats.)

You can search for similar pictures in a folder, or compare one picture to a folder of pictures. You can compare a maximum of 30.000 pictures. (100.000 pictures for one-to-folder seach). PixCompare works best on photographic pictures.

PixCompare also identifies two pictures when:

• one of them is grayscale;
• they don't have the same size / aspect ratio;
• they have a different intensity;
• they have a different pixel-depth;
• one of them is blurred or rotated.
