Converting GIF to AVIF produces dramatically smaller files while supporting transparency and animation. AVIF is the most efficient format for this kind of content; a 2 MB animated GIF can compress to 200 KB as AVIF.

AVIF encoding is slow, especially for animation. At matched perceived quality the file is often 80–90% smaller than the source GIF. Animated AVIF support in browsers is still catching up; test your target audience.
Static AVIF works in Chrome 85+, Firefox 93+, Safari 16+. Animated AVIF support is newer; Chrome and Firefox handle it, Safari's animated AVIF support is partial.
GIF is a 1987 format limited to a 256-color palette. Its lasting relevance is support for simple animation, which kept it in the meme ecosystem after PNG replaced it for static images. GIF compression is lossless within its palette constraints but usually worse than PNG for the same image.
AVIF is an image format built on the AV1 video codec, standardized in 2019. It supports HDR, wide color gamut, 12-bit depth, alpha, and animation. At matched perceived quality it's typically 50% the size of JPG and 20% smaller than WebP. Support is near-universal in modern browsers but spottier in image editors.
Yes, but browser support for animated AVIF is less universal than animated WebP. Test your target browsers.
Typically 80–90% smaller, sometimes more. GIF is extremely inefficient for animation; AVIF's video-codec-based compression is dramatically better.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
