How to use JPG to AVIF

  1. 1

    Add JPG images

    Drop one or more JPG photos. AVIF is already selected.

  2. 2

    Set the quality

    60–70 in AVIF already looks like a high-quality JPG.

  3. 3

    Convert and download

    AVIF encoding is heavier than JPG, so large batches take a little longer. Download each file or a ZIP.

What is AVIF?

AVIF is a modern image format based on the AV1 video codec. It compresses photos far better than JPG and even WEBP: at the same visual quality, AVIF files are often around 50% smaller than JPG and 20–30% smaller than WEBP. It also supports HDR, wide colour and transparency.

Browser support

AVIF is supported by Chrome, Edge, Firefox, Opera and Safari 16.4+, which covers the vast majority of users. For the few older browsers left, serve a JPG fallback with the HTML <picture> element.

Tips

  • AVIF quality numbers are not the same as JPG: 60–70 already looks excellent.
  • Encoding AVIF is slower than JPG; give large batches a moment.
  • Prefer wider compatibility? Use JPG to WEBP. Need to open AVIF files? Use our AVIF Converter.
