How to convert JPG to AVIF

Why convert JPG to AVIF?

JPG: The default for photographs. Small files and universal support, but no transparency.

AVIF: The newest of the web formats. Exceptional compression, supported by every modern browser.

The conversion happens entirely in your browser. Each file is decoded to raw pixels and re-encoded as AVIF. Nothing is uploaded, and the server only serves this page.
