Why convert GIF to AVIF?

Mainly to get a compact modern still image from a GIF for sites that already serve AVIF — this captures one snapshot of the GIF's first frame rather than reproducing its animation.

Can every browser create AVIF?

No. Canvas AVIF encoding is Chromium-first today. The tool probes encoding support and verifies the download is image/avif — unsupported browsers get a clear error instead of a mislabeled download.

Does AVIF output keep transparency?

Transparent pixels from the GIF's first frame stay transparent when the browser AVIF encoder supports alpha. This tool does not flatten onto an arbitrary background.

Does this keep the GIF's animation? Doesn't AVIF support animation?

AVIF as a format can store animation, but this tool doesn't use that capability — it always encodes a single static AVIF from the GIF's first frame, so an animated source's later frames, timing, and loop are all left out.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a GIF — the tool checks the GIF87a/GIF89a signature bytes, not just the filename or extension, before decoding.

What GIF to AVIF conversion does

Convert a GIF to a single static AVIF image directly in your browser, with adjustable quality. AVIF itself can support animation, but this tool always outputs one static frame — taken from the GIF's first frame — regardless of whether the source GIF was animated.

How to convert GIF to AVIF

Choose a GIF file.
Adjust AVIF quality if needed.
Select Convert & download.
Save the .avif file from your browser downloads.

Why use this conversion

AVIF can shrink UI graphics and photos for sites that already serve modern image formats — useful here for delivering a compact still snapshot of a GIF rather than reproducing its motion.

Transparency and output quality

Transparent pixels from the GIF's first frame stay transparent when the browser's AVIF encoder supports alpha; this tool does not flatten onto an arbitrary background before encoding. The quality slider defaults to 90%. Lower values usually shrink the file and can introduce compression artifacts. Smaller files are not guaranteed for every source image.

Privacy and local processing

Processing occurs locally in the browser.
Files are not uploaded to Looty Tools for conversion.
Converted files remain on your device.

Limits and known issues

Input: GIF (.gif) only, up to 25.0 MB and 8,192 px per side.
Canvas AVIF encoding is Chromium-first today. Unsupported browsers show a clear error instead of a mislabeled download, and usage is not recorded for a failed conversion.
It's easy to assume AVIF's own animation support would carry a GIF's motion through — it won't here. This tool always writes a single static AVIF from the GIF's first frame; every later frame, its timing, and its loop are discarded regardless of the source.
Metadata is not preserved in the downloaded file.
