Why convert JPG to JXL?
JXL produces 30-60% smaller files than JPG at the same visual quality. This saves storage, reduces bandwidth costs, and speeds up page load times for visitors using browsers that support JXL.
Can I serve JXL with a JPG fallback?
Yes. Use the <picture> element with <source type="image/jxl"> for JXL and <img> as JPG fallback. Browsers that support JXL will use the smaller file.
Is JXL better than WebP?
For photographic content, JXL typically offers 10-30% better compression than WebP. JXL also supports lossless JPEG recompression, HDR, and wider color gamuts. The main disadvantage is limited browser support (for now).
