How to convert JPG to AVIF

  1. Drop the images.
  2. Pick a quality.
  3. Press Convert and download the AVIFs.

What happens to your file

Browsers cannot yet encode AVIF for a page, so the file is uploaded, encoded on Fylane’s servers at your quality, and deleted on schedule. Encoding is slower than JPG — a few seconds for a large photo.

AVIF is shown by every current browser and most phones; older desktop software and some upload forms refuse it. Keep a JPG for those.

Questions

AVIF or WebP?
