Convert AVIF to GIF

AVIF to GIF converts AV1-based AVIF images into GIF so they work in older apps, email clients and platforms that don’t accept AVIF. Animated AVIFs keep their frames and timing where your browser supports the WebCodecs ImageDecoder API (Chrome, Edge and recent Firefox); elsewhere, the first frame is converted to a still GIF.

    Drop a .avif file — still or animated.

    Set speed (animated) or display time (still), plus output width and quality.

    Convert

    Click Convert to GIF and download.

AVIF vs GIF

AVIF (AV1 Image File Format) was published by the Alliance for Open Media in 2019. It stores images with the AV1 video codec, supporting millions of colours, HDR, full alpha transparency and animation — at a small fraction of a GIF’s size. GIF, by contrast, works literally everywhere, including old software and most email clients.

Converting AVIF to GIF trades efficiency for compatibility: expect the GIF to be noticeably larger and limited to 256 colours per frame. To go the other way and get a modern, compact still, use GIF to AVIF.

If only the first frame converts

Reading the individual frames of an animated AVIF requires the WebCodecs ImageDecoder API. If your browser lacks it, you’ll get a single-frame GIF — open the page in Chrome or Edge to convert the full animation. Similar modern formats are covered by Sticker to GIF (animated WebP) and Images to GIF (APNG and others).

AVIF to GIF FAQ

How do I convert AVIF to GIF?

Drop the AVIF file into this tool, adjust the width and quality, and click Convert to GIF. Animated AVIFs keep their animation in Chrome, Edge and recent Firefox.

Can animated AVIF be converted to an animated GIF?

Yes, in browsers with the ImageDecoder API. The tool reads every frame with its original duration and rebuilds the animation as a GIF.

Why is the GIF larger than the AVIF?

AVIF uses the AV1 codec, which is far more efficient than GIF’s LZW compression. Converting for compatibility usually increases file size.

Are my files uploaded to a server?

No. GifRush processes everything locally in your browser using JavaScript, Canvas, Web Workers and WebCodecs. Your files never leave your device, and closing the tab discards them.
