AVIF Compressor
Compress
The canvas previews the compressed result live as you adjust the settings. Click Compress for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.
Your images are processed locally in your browser and never uploaded to any server.
AVIF downloads from the web or exports from design tools are often tuned conservatively. Re-compress them here with precise quality control, entirely in your browser: keep AVIF output for the smallest possible files, or switch to WebP where encode speed matters. Transparency is preserved on every path.
How to use the avif compressor
- Add your AVIF files by drag-and-drop or the file picker.
- Keep AVIF output for maximum compression, or pick WebP (encodes faster).
- Adjust quality; AVIF needs less than you think, 60–70 is usually plenty.
- Download files individually or as one ZIP.
Frequently asked questions
Can this tool output AVIF?
In Chromium-based browsers, yes: AVIF encoding works in the canvas pipeline and the tool uses it. Browsers that cannot encode AVIF get an honest message, and WebP output (similar compression, faster encoding) is always available as the pragmatic choice.
Why re-compress a format as efficient as AVIF?
Export tools often default to quality 90+, which leaves real headroom. Re-encoding at 60–70 frequently cuts another 20–40% with no visible change, because AVIF degrades far more gracefully than JPG at low quality.
Is AVIF encoding slower than other formats?
Genuinely, yes: the AV1 codec explores more compression strategies, so large images take a few seconds each. Encoding runs in background threads and results land as they finish; the page never freezes.
