What does JPG to AVIF do?

JPG to AVIF is aimed at workflows where aggressive compression and modern delivery matter most. AVIF can produce very compact files, which makes it interesting for performance-focused websites, especially when image weight is a bottleneck.

Because not every workflow is ready for AVIF, the live preview is useful here. You can quickly check the result and decide whether the smaller file size fits your publishing or testing needs before downloading.
