gifdiff is a specialized comparison tool for GIF image files, part of the gifsicle toolkit. It performs pixel-by-pixel comparison between two GIF files and reports the differences found.
The tool can produce a visual difference image when using the -o flag, where differing pixels are highlighted. Without the brief flag, gifdiff provides detailed information about differences in image dimensions, color palettes, animation frames, and pixel data.
