AVIF is a modern format that’s typically 30–50% smaller than JPG at the same quality. Conversion happens in your browser — where your browser can’t write AVIF directly, a lightweight in-browser encoder is used, so it still works in every modern browser. Nothing is uploaded, and metadata is stripped on re-encode.
