GIF to AVIF Converter
Convert a GIF to an AVIF still image for a much smaller file on the modern web. Conversion happens in your browser; nothing is uploaded.
Your images never leave your device
How to use GIF to AVIF
- Drop your GIF files on the page or pick them from your device.
- Wait while each file is converted to AVIF. AVIF encoding is slow, and large photos can take several seconds.
- Download the AVIF files one by one, or all together as a zip.
Frequently asked questions
Is AVIF much smaller than GIF?
For photo-like images, yes, often by an order of magnitude. For tiny flat graphics the difference is smaller and the result can even be larger.
Does the AVIF keep the animation?
No. The converter writes a still image from the GIF's first frame.
Which browsers show AVIF?
Current versions of Chrome, Edge, Firefox and Safari. Older browsers and many apps do not, so keep a fallback for those.
Are my GIF files uploaded anywhere?
No. The conversion runs in your browser using WebAssembly, so your GIF files stay on your device. There is no signup, no watermark and no cost, and you can convert a whole batch and download it as a zip.
About GIF to AVIF
AVIF is among the most efficient image formats, so the savings against a GIF can be dramatic for photo-like or heavily dithered images. It supports transparency, which GIF graphics often rely on. The conversion is mostly used by site owners replacing old GIF assets with something lighter.

The output is a still image from the first frame, so an animated GIF loses its animation. AVIF encoding takes more time than other formats, with large images needing several seconds. The 256 colors of the original remain; AVIF cannot restore what the GIF lacks. Because AVIF is lossy for photos, dithering patterns in the GIF can be smoothed or turned into slight artifacts. Many programs and upload forms still do not accept AVIF, so use it on websites and keep a PNG or JPG elsewhere.
GIF is lossless but limited to a 256-color palette per frame; AVIF is lossy or lossless, compressed with AV1. Both formats can store transparency, so transparent areas in the GIF file stay transparent. GIF files can be animated, but the result is a still image made from the first frame. Compatibility: Recent versions of Chrome, Edge, Firefox and Safari display it. Support in editors, email clients and upload forms is still patchy.
