Swapping JPGs for AVIF often halves image weight with no visible quality drop — one of the biggest wins for page speed.
Saving bandwidth and storage
Smaller files mean lower hosting bandwidth and less storage. AVIF is ideal for image-heavy galleries and catalogues.

Frequently asked questions
Why convert JPG to AVIF?
AVIF typically produces files 30–50% smaller than JPG at the same visual quality. For websites, that means faster loads and better Core Web Vitals scores.
Does this work in every browser?
Yes. AVIF encoding runs through a built-in WASM encoder, so it works in Chrome, Edge, Firefox, and Safari alike. The encoder downloads only the first time you convert to AVIF, and encoding can take a moment on large images.
Is my JPG uploaded to a server?
No. The image is encoded to AVIF entirely in your browser. Nothing is uploaded, so your files stay private.
Can I control the AVIF file size?
Yes. The quality slider trades file size against sharpness. AVIF holds up well even at lower quality, so you can push the size down further than with JPG.
