DiffImg is a simple graphical tool for comparing images and searching for differences between them, which is characterized by speed and efficiency. The program allows you to compare two images of the same size with each other. After the graphic files have been pointed out by the user, they are analyzed in detail and the information about the different files is displayed in the form of a colour mask.

DiffImg offers three methods of comparison - with respect to the channel, average channel and brightness of the image. They can be changed from the configuration options, where you will also find an option specifying the level of transparency for the error mask. DiffImg is equipped with a simple batch processing mode, as well as the function of comparing individual images from the folder (provided that we have a different folder containing the same number of image files).

The tool can support BMP, GIF, ICO, JPG, MNG, PBM, PGM, PNG, PPM, TGA, TIFF, XBM and XPM images.
