People Also Use
Turn your GIF files into AVIF right in the browser — this tool will shrink each file and hand it back in seconds, with nothing uploaded to any server. GIF is the classic animation format, limited to 256 colours per frame but universally supported for short loops. AVIF is the newest AV1-based format with the best compression available today, often half the size of JPEG. The conversion keeps your image faithful while switching it into the AVIF container. Free, private, unlimited, and watermark-free.
How to Convert GIF to AVIF
Add your GIF file
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to AVIF
Pick a quality level if you want to trade a little detail for a smaller file, then press Convert. Encoding is instant for most images.
Download
Save each AVIF file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert GIF to AVIF?
The main reason is modern web delivery, offering the smallest files at a given quality with transparency and HDR. GIF excels at simple animations and small graphics that fit inside 256 colours, but when you need smaller, widely-supported files, AVIF is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
Converting into AVIF re-encodes the image, and because AVIF is lossy you control the trade-off with the quality setting. At high quality the difference is invisible.

Tips & Things to Know
Check the file size after converting
Expect the AVIF file to be noticeably smaller than your GIF. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your GIF stay transparent in the AVIF — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your GIF files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
Tune the quality if you need to
For AVIF you can trade a little detail for a smaller file using the quality slider. At around 90% the difference is invisible to the eye, while the file can be much smaller — useful for web images and email attachments.
