Your images never leave your browser

All processing happens locally on your device. Nothing is uploaded to a server, stored, or tracked.

Squeeze AVIF files even further by re encoding at a lower quality target for storage heavy use. AVIF is already efficient, but balanced to small saves more for web delivery.

How it works

Why compress AVIF?

Squeeze AVIF files even further by re encoding at a lower quality target for storage heavy use. AVIF is already efficient, but balanced to small saves more for web delivery.

How AVIF compression works

AVIF is a lossy format, so compression reduces file size by discarding some visual detail. Higher quality settings preserve more detail but produce larger files.

Quality settings explained

The balanced preset balances quality and file size for most uses. Lower quality settings cut size further but introduce more compression artifacts.

Is compression private?

AVIF compression happens in a local web worker. Your image never leaves your browser.

Batch compress AVIF

Re-encode a batch of AVIF files at a lower quality target to save even more space. Free, private, batch ZIP, and no uploads.

Frequently asked questions

Is AVIF already the smallest option?

AVIF is one of the most efficient codecs, but re encoding at a lower quality can shrink it further while keeping detail at balanced.

When should I recompress AVIF

When the AVIF you have is larger than needed for delivery. Lowering from high to balanced often cuts size with little visible change. See WebP vs AVIF for comparison.

Can I bulk compress many AVIF files without uploading

Yes. Add your AVIF files, pick quality, and compress together. All processing happens locally in your browser and you can download a ZIP.
