AVIF stores an image compressed with AV1, the video codec, inside the same kind of container as HEIC. Websites use it because the files are small, so an image saved from a browser can end in .avif. Current Chrome, Firefox and Safari open it, but many editors, older apps and upload forms don't.
AVIF compresses far better than JPG, so expect the JPG to be larger for the same look. JPG has no transparency, so transparent areas are filled with white.
AVIF can hold HDR and wide-gamut color; the JPG is standard 8-bit color, so very bright highlights come out flatter. An animated AVIF becomes its first frame.

AVIF compresses better. Pick Smaller file if size matters more than detail.
The browser does the decoding, so an old browser can't read AVIF. Try a current Chrome, Firefox or Safari.
Not in JPG. Convert AVIF to PNG instead, which keeps it.
