What is AVIF and why does it matter?

AVIF (AV1 Image File Format) is based on the AV1 video codec developed by the Alliance for Open Media. It offers compression efficiency significantly beyond both JPG and WebP — at the same visual quality, AVIF files are typically 50% smaller than JPG and 20–30% smaller than WebP.

Browser support is now widespread: Chrome, Firefox, and Safari 16+ all support AVIF natively. For websites targeting modern browsers, AVIF is the best choice for photographic images. The main limitation is encoding speed (slower than JPG or WebP) and limited support in desktop image editing applications.

Note: if your browser doesn't support AVIF encoding via OffscreenCanvas, the tool will alert you. Chrome and Edge have the best AVIF encoding support. Firefox and Safari may fall back to PNG in some configurations.

How to convert JPG to AVIF

  1. 01

    Drop your JPG files

    Open the converter and drag your JPGs onto the tool.

  2. 02

    Select AVIF output

    Click AVIF in the format selector. Default quality is 60%, which looks excellent for AVIF's encoding style.

  3. 03

    Wait for encoding

    AVIF encoding is slower than JPG or WebP. Large images may take a few seconds each.

  4. 04

    Download

    Download files individually or get all as a ZIP.

Common questions

Why is the default quality 60% for AVIF?
AVIF quality scales differently from JPG. A quality of 60% in AVIF produces results comparable to 85% JPG quality — the scale isn't linear. Start at 60% and adjust from there.
Does AVIF work in all browsers?
Chrome 85+, Firefox 93+, and Safari 16+ support AVIF display. Encoding (used here) requires Chrome or Edge for reliable results. The tool will show an error if your browser can't encode AVIF.
Is AVIF better than WebP?
For photographic images, AVIF typically achieves 20–30% better compression than WebP at equivalent quality. For graphics and illustrations the difference is smaller. WebP has broader software support.
