So it's supported now by all the major browsers (Firefox support coming soon) as well as all the major OSes.

I believe it's been available in Firefox for a while now, just behind a feature flag

Firefox 158 will ship with it on by default: https://groups.google.com/a/mozilla.org/g/dev-platform/c/3YM...

Next up: Phones and cameras. It would be so great to have a common image format again after years of fragmentation.

iPhones have supported it for 3 years.

Taking photos in JPEG XL? That's what I meant; the consumer side is nice, but if everybody keeps taking AVIF, HEIC, and JPEGs, we're missing an important part. (Sure, smaller websites are nice too, but I can have that today with WebP, as CDNs need to serve multiple formats anyway.)

Took them long enough with a few embarassing detours, but a welcome news nonetheless! Has anyone ~blogged about some of the internal dynamics that lead the G ship to course-correct, would be curious to read?

I doubt anyone that wants to keep their job in big tech would ever publish something like that.

Nice. I added support for JXL to a low traffic chan board after Firefox added experimental support. I would honestly be surprised if anyone ever upload anything in that format but I can see some use cases for it after reading this thread. I am curious if some day JXL would ever be as popular as JPG or PNG and what would drive that change. Art sites perhaps? Maybe DeviantArt could add support for it.

Art sites get the biggest gain with JXL. They can losslessly repackage every single JPEG uploads they have for practically zero cost. Existing PNG can also be losslessly compressed to JXL too, and just wrapping JXL around PNG yields improved compression (Note for last part: it is still in proposal status)

I love the codec and am glad to see it supported again. They overcame the security issues using a rust SIMD port. I wonder what "approximately as fast as the best non-memory-safe alternative" means - the wording suggests they didn't beat the C++ implementation, but how close is it?

Here's a benchmark over time of jxl-rs (Rust) vs libjxl (C++) across both memory usage and performance: https://jxl-rs-perf.lucaversari.it/. I'm inclined to trust that it's a decent benchmark since it's from Luca Versari, a key person in the original JPEG XL standardization effort and development of libjxl, and is now the main developer of jxl-rs.

Seems to be between a little and a lot faster in almost all of the tests.

looks great - jxl-rs is faster since June 2026 (using just a bit more RAM)

Are they switching it on in Android Chrome? That would complete the picture of at least baseline support... eventually... when a decent percentage of Android phones actually get that version.

But Safari (MacOS or iOS) still doesn't support the progressive rendering shown here, nor animation, if caniuse is up to date:

Not to be a downer — it's one necessary step on the road.

Excellent, I wanted to ask whether this release will support in Android WebView and iOS WKWebView components as well? Or only the Google Chrome browser will support this feature?

I'll kind of miss (not actually) the early 2000s codec vibe I get when I share an image with people on Signal and half of them say, "I can't view it."

Wanted to use this for building a viewer for astronomical imagery but the decoder resamples to 8 bits internally unfortunately.

Have to stick with AVIF which supports up to 12 bits.

After some time, this seems to be the first image format, now in production, not being just the nus product of some video format.
