Compress AVIF files with a quality slider
This AVIF compressor re-encodes an AVIF image at a lower quality setting so the file takes up less space. Choose an AVIF file, move the quality slider, and the tool shows the compressed size next to the original before you download, so the trade-off between file size and visible quality stays in your hands rather than being decided for you.
When AVIF compression makes sense
It fits when a site or app already serves AVIF and individual files are heavier than they need to be, for example photos exported at maximum quality for a page where a smaller file would look the same. Lowering quality in steps and comparing sizes helps you stop at the point where savings are real but artifacts are not yet visible.
Good to know
AVIF encoding depends on your browser: only browsers with AVIF encoding support can do the re-encoding, and if yours cannot, the tool shows a clear message instead of producing a broken file. Files up to 10 MB are accepted, and your original file is never altered on your device.
Frequently asked questions
Why does it say AVIF is not supported in my browser?
Compression here means decoding your file and encoding a new AVIF inside the browser. Some browsers display AVIF but cannot encode it. When encoding support is missing, the tool explains the limit instead of switching formats.
Will compressing an AVIF reduce its quality?
Yes; that is the trade. A lower quality setting gives a smaller file with more artifacts. The size comparison shows the saving first, and your untouched original lets you rerun at a higher setting.
Are my images uploaded to a server?
No. Files are processed in your browser and never sent to the site's server. Your AVIF stays on your device from selection to download, with nothing uploaded or stored.
