About the JPG to AVIF Converter
AVIF is a modern image format that often makes files 30–50% smaller than JPG at the same visual quality, which means faster websites and less storage. This free JPG to AVIF converter re-encodes your JPG photos into AVIF using your browser's built-in encoder.
Because everything happens locally, your images are never uploaded. Choose a quality level, convert single or multiple files, and download the compact AVIF results for use on modern browsers and apps.

Frequently Asked Questions
Why is AVIF smaller than JPG?
AVIF uses the modern AV1 compression scheme, which encodes detail far more efficiently than the decades-old JPEG method, producing smaller files at comparable quality.
Which browsers support AVIF?
Recent versions of Chrome, Edge, Firefox and Safari can display AVIF images. For older software you may prefer to keep a JPG copy as a fallback.
Does my browser support AVIF encoding?
Most current desktop browsers can create AVIF files. If your browser cannot, the tool will let you know so you can try an up-to-date one.
Are my JPGs uploaded to a server?
No. Conversion runs in your browser, so your photos stay on your device throughout the process.
