About Image to AVIF

AVIF is the newest image format and usually the smallest: around half the size of JPG at equal quality, with transparency and wide color support. Use it for websites and apps where every kilobyte matters. Encoding runs on your device, so large batches take a little longer than other converters.

  • AVIF is supported in all current browsers, but some older email and desktop apps cannot open it.
  • Encoding is slower than WebP; expect a few seconds per large photo.
  • Keep a JPG or WebP copy as a fallback if your audience uses older devices.

How to use it

  1. 1Drop your images.
  2. 2Set the quality. 60 to 70 is typical for AVIF and still looks excellent.
  3. 3Download the AVIF files.

Questions

How much smaller is AVIF?
Typically 40 to 50% smaller than JPG and 20 to 30% smaller than WebP at matching visual quality.
Can I open AVIF on my computer?
macOS Monterey and later, Windows 10 and later with the AV1 extension, and all major browsers open AVIF.
Does it upload my images?
No. Everything runs in your browser, so your photos never leave your device.
