GIF to AVIF
Replace a still GIF with a tiny AVIF. Animated files become a single image taken from the first frame.
GIF to AVIF for modern, lightweight stills
GIF is nearly four decades old, and AVIF is one of the newest image formats. If you're moving older web graphics or preview images into a modern format, this GIF to AVIF converter can reduce them to a fraction of their size, with transparency preserved.
Keep in mind that the result is one still image. It's best suited to single-frame GIFs, and to animated GIFs where you only want a poster or preview picture.
How to convert GIF to AVIF
AVIF takes more processing than other formats, but small GIFs still convert quite fast.
- 1
Bring in your GIFs
Pick files from your site's image folder. Batches can contain up to 20.
- 2
Set a generous quality
Limited-palette images have hard edges, so a quality from 75 to 90 keeps them cleaner than low settings.
- 3
Encode to AVIF
Press the convert button. Only the first frame is used, and transparency is carried over.
- 4
Compare sizes
Check the result cards. Keep the AVIF where it's a real improvement, and the smaller file where it isn't.
Which GIFs benefit
| GIF | AVIF result |
|---|---|
| Large photographic banner | Very big savings |
| Illustration with many colors | Big savings |
| Logo with sharp edges | Moderate savings at high quality |
| 16 × 16 icon | No real benefit; keep the original |
| Animation you need moving | Not suitable |
Handling GIF's hard edges
GIFs have limited palettes, and many have dithering: tiny patterns of dots that fake extra colors. These are hard for any modern encoder, because they look like fine detail. At low quality, AVIF tends to smooth the pattern into a soft blur. That can actually look nice on a photo, but it may look wrong on a crisp logo.
If your graphic has sharp edges, use a high quality setting, and check it at 100% zoom. If it still doesn't look right, a lossless GIF to PNG may be a better fit.
Browser support and fallbacks
Chrome, Edge, Firefox and Safari 16 onward all display AVIF. If you need to reach older browsers, use the picture element with a fallback. GIF to WEBP gives you a broadly supported alternative, and you can simply keep the original GIF as the final option.
Free and private

Frequently asked questions
No. AVIF can technically support animation, but this converter takes only the first frame, so the output is a still image.
Drop the GIF on this page, choose a quality and press Convert to AVIF. Your browser encodes its first frame as a still AVIF image.
Yes. AVIF has a full alpha channel, so a transparent GIF stays transparent.
Not always. Photographic GIFs and large banners shrink a lot. Very small icons can come out about the same size or larger, since AVIF has a little overhead of its own.
They're similar for this type of image. AVIF is often smaller, while WEBP encodes faster and has somewhat wider software support.
AVIF files carry some header data that matters on very small images. A tiny icon is often better left as a GIF or PNG.
No. The encoder runs locally, in your browser.
