About the two formats
GIF
GIF is the old format behind animated memes. Each frame can only use 256 colours, so photos look grainy and files are large for what they show.
AVIF
AVIF uses compression from the AV1 video codec and usually makes the smallest image files of any common format. Browser support is broad, but desktop apps are still catching up.
