JPG to AVIF Converter – Free, Fast & No Upload

AVIF is one of the most efficient image formats for the web, and it can make photos even lighter than WebP. This JPG to AVIF converter helps you prepare lean images for your site, right in your browser.

Convert JPG to AVIF

Add your JPG files, check the settings and download them as AVIF. Batch conversion, no sign-up and no watermark.

Check browser support first

AVIF output in this tool works in Chrome and Edge. In other browsers it works only if the site server supports AVIF. If the conversion does not run in your current browser, try Chrome or Edge. Also remember that visitors need a browser that can display AVIF, and very old browsers cannot.

How to convert JPG to AVIF

  1. Add JPG files with drag and drop or “Choose files”.
  2. Select AVIF under “Convert to”.
  3. Set “Quality”. For AVIF, 60 to 75 is often enough, because it keeps detail at lower values than JPG.
  4. Set “Max width (optional)” to the largest size your layout needs, then download.

Choosing AVIF quality

AVIF handles low quality values gracefully, so start around 65 and compare it with the JPG. Look at skies, skin and text edges, where compression shows first. Raise the value if you see banding or smearing. Lower it if you still see no difference.

AVIF or WebP?

AVIF is often smaller, but WebP is supported a bit more widely and is quicker to encode. Many sites serve AVIF to browsers that support it and fall back to WebP or JPG for the rest. For a simple setup, JPG to WebP is the safer single choice.
