How to convert AVIF to JPG

  1. Pick one or more .avif files (or drag them onto the picker).
  2. Adjust the JPEG quality slider — 90 is a safe default; 75 produces visibly smaller files.
  3. Optionally choose a background colour for transparent pixels.
  4. Press Convert to JPG, then download each result.

Common use cases

Frequently asked questions

What quality setting should I pick?

90 keeps photos visually identical to the AVIF source. 75 is a common web-quality setting. Below 60, JPEG artefacts become visible.

Will I lose image detail?

AVIF can encode finer detail than JPEG at the same file size, so a roundtrip is slightly lossy at low quality. At 90+ the loss is imperceptible for photos.

Does it run on mobile?

Yes — Safari on iOS 16+, Chrome and Firefox on Android all decode AVIF and encode JPEG via the canvas API.
