Convert JPG to AVIF and cut photo sizes in half

AVIF can store the same photo in roughly half the bytes of a JPEG. For image-heavy sites such as portfolios, stores and blogs that translates into faster loads and lower bandwidth bills.

How it works

JPG to AVIF Converter: 3 simple steps

  1. 1

    Add your JPG or JPEG files.

  2. 2

    Choose AVIF and a quality between 60 and 70 for photos.

  3. 3

    Download the results or the ZIP archive.

Drop in your JPG photos and this tool converts them locally. If your browser can't encode AVIF it produces WebP instead, so you never end up with a broken result.
