Why convert GIF to AVIF?

- Squeezing a GIF graphic to the smallest modern format.
- Getting a crisp, full-colour still from a limited-palette GIF.
- Optimising image weight beyond what WebP achieves.
GIF vs AVIF
GIF · Graphics Interchange Format
GIF is a legacy format capped at 256 colours, best known for short animations. As a still image it's been superseded — converting a GIF gives you a full-colour, widely-editable image (the first frame, for animated GIFs).
AVIF · AV1 Image File Format
AVIF is built on the AV1 video codec and is one of the most efficient image formats available — often 50% smaller than JPG with better quality, plus transparency and HDR. Encoding is slower and support, while broad, is slightly newer than WebP.
