About this tool

Convert JPG to AVIF for much smaller files

Drop in a JPG (or several) and download AVIF versions that are typically 30–50% smaller at the same visual quality. AVIF is a modern image format built on the AV1 codec — ideal for speeding up websites and saving storage.

Why AVIF over JPG

  • Smaller files — better compression than JPG, and usually better than WebP too.
  • More colour — supports HDR and wide colour gamut.
  • Transparency — unlike JPG, AVIF has an alpha channel.

Browser support

AVIF works in current Chrome, Firefox, Edge and Safari. For older browsers keep a JPG/WebP fallback via the HTML <picture> element. Conversion happens entirely in your browser — your images are never uploaded.
