GIF to AVIF: when it makes sense
AVIF is overkill for simple GIFs but excels when the source has many colours or noisy content. For richly-coloured GIFs being used as still images, AVIF often produces files another 10–20% smaller than WebP.
If browser support is your concern, WebP covers a wider audience. If size is paramount and the audience is modern browsers, AVIF wins.
Static output only
This converter writes still AVIF: the first frame of the GIF, re-encoded. If you need to keep the animation, you would need a tool that produces AVIF Image Sequence files, which we do not generate.
How the converter works
- Drop or select one or more GIF files (up to 20 MB each).
- We grab the first frame and encode it with libvips + libaom (quality 60, encode speed 6).
- Download the AVIF ready for the web.

No. We extract the first frame and output a static AVIF image. For animation use a dedicated animated-AVIF tool.
It works in Chrome, Firefox, <a href="https://caniuse.com/avif" target="_blank" rel="noopener">Safari (16.4+)</a>, Edge and Opera — over 90% of modern global traffic. Use <picture> with a WebP or PNG fallback for the rest.
Often 70–90% smaller for the same visual frame, because GIF's 256-colour palette and LZW are far less efficient than AV1 intra-frame coding.
