Why convert JPG to AVIF?

AVIF uses the AV1 video codec's intra-frame compression to deliver image quality that beats both JPG and WebP at the same file size. For photographic content the typical win over JPG is 40–55% at the same perceived quality.

It is supported by Chrome, Firefox, Safari (16.4+), Edge and Opera. The combined market share is high enough to use AVIF as your primary format and fall back to JPG or WebP via <picture> for legacy browsers.

AVIF vs WebP vs JPG

At the same visual quality on photographic content: AVIF is the smallest, WebP sits in the middle (about 25–35% smaller than JPG), and JPG is the heaviest of the three. The price of AVIF is a slower encode (we ship sensible defaults so this stays under a second per image) and a slightly slower decode in the browser — usually invisible.

If your target is photography portfolios, hero images, or any image-heavy landing where bandwidth matters, AVIF gives the biggest savings.

How the converter works

  1. Drop or select one or more JPG files (up to 20 MB each).
  2. We re-encode with libvips + libaom at a balanced speed/quality preset (quality 60 by default, encode speed 6).
  3. Download the AVIF ready to ship to production.

Frequently asked questions

Yes, significantly. For most photographic content AVIF is 40–55% smaller at the same visual quality. The savings shrink for very small images (under 50 KB) where format overhead matters more.

Chrome, Firefox, <a href="https://caniuse.com/avif" target="_blank" rel="noopener">Safari (16.4+)</a>, Edge and Opera support AVIF, covering well over 90% of global traffic. For legacy clients use the <picture> element with a JPG fallback.

No, we default to a high-efficiency lossy preset. AVIF supports lossless mode too, but for photographs lossy at quality 60 looks identical to the JPG source while being much smaller.

AVIF uses a more sophisticated encoder than JPG. We tune for "fast enough for the web" — a few hundred milliseconds per image — which is plenty for a one-off conversion.
