How to use

  1. Choose one or more JPG or JPEG photos.
  2. Leave the output format on AVIF.
  3. Set the quality, or use Target Size for a maximum file size.
  4. Convert and download the AVIF file or a ZIP of the batch.

Key benefits

  • Private

    The photo is decoded and encoded in your browser. It is not uploaded.

  • Batch ready

    Several JPG files can become AVIF files in one run.

  • Measured compression

    Target Size mode measures the real AVIF blob instead of estimating the size.

Why convert JPG to AVIF

People convert JPG to AVIF when they want a modern format that can shrink photographs efficiently. Savings depend on the picture and the quality you choose.

If you need a specific maximum size, use Target Size or the 100 KB and 200 KB tools with AVIF selected.

Quality notes

The quality slider uses the same 10–100 range as WebP and JPG. AVIF's visual result at a given number can differ from WebP at the same number.

Camera metadata is not copied into the new file, because the converter builds the image from pixels.
