JXL vs AVIF: Which Should You Use?

JPEG XL (JXL) and AVIF are both designed to replace legacy JPG. They take different technical approaches and currently sit in very different places on the browser-support curve.

Encode speedFaster than AVIF, often 2–4×Slow — requires precomputation for production use

Recommendation

For shipping web images today, AVIF is the right choice — JXL's browser support remains too narrow. Watch JXL closely; if Chrome restores support and Safari adoption grows, JXL is technically the more attractive long-term format because of its lossless JPG re-encoding.
