What is a .gif file?
GIF (Graphics Interchange Format) is a raster format limited to a 256-color indexed palette per frame, using lossless LZW compression. It supports simple frame-based animation and a single fully transparent palette index. It is widely used for short looping animations and low-color graphics.
How to use this file
Use an example GIF to test animated-frame decoding, palette and transparency handling, frame timing, and conversion to modern formats like WebP or MP4.
