AVIF is a modern image format built on the AV1 video codec, and it compresses far harder than the decades-old GIF format. This tool draws your GIF onto an HTML canvas and re-encodes it as AVIF using your browser's built-in encoder, so the conversion happens on your own machine and the file is never sent anywhere.
Why AVIF beats GIF for static images
A GIF is limited to a 256-colour palette and uses a compression scheme from 1987, which is why photographic GIFs look banded and still weigh a lot. AVIF keeps the full colour range and typically lands a fraction of the size at the same visual quality. For a still graphic or a photo saved as GIF, converting to AVIF usually cuts the file dramatically while looking cleaner.
The animation caveat
AVIF can hold animation, but a browser canvas only captures a single frame — whatever frame is showing when it reads the image. So if you feed in an animated GIF, you will get a still AVIF of one frame, not a moving image. This tool is meant for converting static GIFs or grabbing a single frame; it is not an animated-GIF-to-animated-AVIF converter.
Browser support matters
Encoding AVIF requires a reasonably recent browser (current Chrome, Edge, Opera and Firefox can do it). If your browser cannot produce AVIF, the download will silently fall back to another format or fail — in that case update the browser or use a different converter. Decoding AVIF to view it is even more widely supported than encoding.
Frequently Asked Questions
Will my animated GIF stay animated?
No. The converter captures a single frame from the canvas, so an animated GIF becomes a still AVIF. Use it for static images or to extract one frame.
How much smaller will the AVIF be?
It varies with the image, but AVIF routinely lands well under the size of the same picture as a GIF because it is not stuck with a 256-colour palette and uses far newer compression.
Is the image uploaded to a server?
No. The GIF is decoded and re-encoded on a canvas in your browser. Nothing leaves your device.
Why did the download fail or come out as another format?
Your browser probably cannot encode AVIF. Update to a current version of Chrome, Edge, Opera or Firefox and try again.
