Supports: AVIF
AVIF compresses far better than GIF, but GIF is the format every browser, email client, chat app, and forum has accepted since 1987 — so when you need a clip to just work everywhere, you convert back. This tool turns a still AVIF into a static GIF and an animated AVIF into a looping animated GIF, with control over the color palette and frame rate so you can manage the inevitable size increase.
.avif onto the page or click "+ Add Files". Animated AVIF sequences are detected automatically and carried over as animated GIFs.| Property | AVIF (source) | GIF (output) |
|---|---|---|
| Released | 2019 (AV1 / AOMedia) | 1987; GIF89a extensions 1990 |
| Codec | AV1 intra frames in HEIF | LZW-compressed indexed color |
| Colors | 8/10/12-bit, millions+ | 256 max per frame (8-bit) |
| Transparency | Full alpha channel | 1-bit on/off only |
| Animation | Yes (Firefox 113+, Chrome, Safari 16.4+) | Yes, via frame sequence + loop |
| Typical size | Smallest of the modern formats | Much larger for the same clip |
| Plays without decoder support | No (needs AVIF-capable app) | Yes, effectively everywhere |
Yes. If the source AVIF contains an image sequence, every frame is carried into a looping animated GIF. A single-frame AVIF becomes one static GIF. The frame delays from the AVIF are mapped to GIF frame timing; you can override the playback speed with the Framerate control if the result runs too fast or slow.
That is expected, not a defect. AVIF uses AV1 inter-frame compression and high bit depth; GIF stores each frame as LZW-compressed indexed color capped at 256 shades, with no cross-frame prediction. The same animation routinely lands several times larger as a GIF. To pull the size back down, lower the palette under Colors, reduce the Framerate, or shrink the resolution in Advanced Options.
GIF indexes each frame to at most 256 colors, so smooth gradients and photographic content show visible banding or posterization. Dithering (the default "By Color Reduction + Dither" mode) hides much of it by mixing adjacent palette colors, at the cost of a slightly grainier, larger file. For photo-quality stills, AVIF to PNG or AVIF to JPG preserve far more color.
Your AVIF is uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. If you would rather not upload large clips, reduce the resolution or frame rate before exporting from the source app to keep the upload small.
In our testing, a 3-second animated AVIF of a few hundred kilobytes expanded into a multi-megabyte 256-color GIF at the same dimensions — the LZW + 256-color ceiling simply cannot match AV1. Dropping the palette to 64 colors and the frame rate to 10 FPS cut the GIF roughly in half with little perceptible loss on flat, illustration-style motion. If you only need the clip smaller rather than as a GIF, convert it back toward AVIF or run the output through our GIF compressor.
