“Overall, we don’t see JPEG-XL performing enough better than its closest competitors (like AVIF) to justify addition on that basis alone,” said Martin Thomson, distinguished engineer at Mozilla, last year. “Similarly, its feature advancements don’t distinguish it above the collection of formats that are already included in the platform.”
So is this a legit take on the technology? Sounds like an expert in the field is pretty convinced that this file format isn’t really worth it’s weight. What does JXL give the web that other file formats don’t?
