JPEG XL vs AVIF
AVIF has broader browser support today, while JPEG XL offers stronger lossless performance and legacy JPEG recompression.
Browser Support and Practical Adoption
AVIF has achieved considerably broader and more consistent browser support, making it the more practical choice for production web delivery today, while JPEG XL's adoption has been hampered by inconsistent browser commitment despite technical strengths that many engineers consider compelling.
- AVIF has achieved considerably broader, more consistent browser support
- This makes AVIF the more practical production choice for web delivery
- JPEG XL's adoption has been hampered by inconsistent browser commitment
Technical Strengths of Each Codec
JPEG XL offers notably strong lossless compression and the ability to losslessly recompress existing JPEG files at reduced size, while AVIF, derived from the AV1 video codec, tends to excel at aggressive lossy compression of photographic content at low bitrates.

- Each codec's strengths suit different content and quality requirements
Frequently Asked Questions
Which codec should I use in production today?
AVIF is generally the more practical choice given its broader, more consistent browser support, despite JPEG XL's compelling technical characteristics.
What is JPEG XL's lossless JPEG recompression?
It can re-encode an existing JPEG file into a smaller JPEG XL file that decodes back to the byte-identical original JPEG, saving storage without any quality change.
