Intent to ship: JPEG XL · A JPEG XL decoder is heading for Firefox 157 https://ilo.im/16flxe

Firefox 157 will enable JPEG XL image decoding by default across all platforms, marking the format's arrival at production-grade support after years of testing.

Google Android System WebView is hiding the #JXL flag. 😭 Even with Chrome browser itself (be it beta, dev, canary), the flag is not accessible via config://flags. It's only available on desktop version.

Not like Mozilla Firefox for Android, there's #JPEGXL support.

Anyway, it’s pretty great news that JPEG XL support will be shipped in all the major browser engines very soon!

The past few years have seen the broader tech industry doing some pretty whack/questionable/wasteful stuff, but this is one piece of unequivocally good news.

Smaller image file sizes for everyone! (and most existing JPEGs can be transcoded losslessly into smaller JPEG XLs)

#JPEGXL

As an aside, Photoshop’s JPEG XL export could still use some work. My two main gripes:

1. Its highest lossy quality setting doesn’t produce output that’s as good as the reference encoder (for some reason its 100% quality level equates to a quality “distance” that’s much worse)

2. Its progressive encoding doesn’t do any saliency detection, which is the truly cool part of JPEG XL progressive encoding (it allows the most important part of an image to be rendered first as it loads)

#JPEGXL

And in case you want to see what the JPEG XL support looks like in terms of the feature tests created for web-platform-tests, here’s the link:

Look at all that green appearing!

WebKit/Safari released support for JPEG XL years ago, but now Firefox and Chrome are close to shipping it as well. They both use the newly completed jxl-rs Rust-based decoder that supports many format features (like progressive decoding) that Safari’s decoder does not.

Hopefully Safari’s decoder won’t now just sit unimproved for years. Progressive decoding and animated JPEG XLs will be very useful.

#WebKit #Safari #JPEGXL

too bad @mastodon or at least @fosstodon (?) doesn't support #jpegxl
Has to use PNG which is much bigger and put more load on the server.

🎉 Behold the pinnacle of technological advancement: a JPEG XL #converter that's so advanced, it runs right in your browser! 🙄 No uploads, no limits, no signups—because clearly, converting images is the wild west of the internet 🤠. Just make sure your #JavaScript is enabled, or you'll be stuck in the dark ages of .jxl oblivion. 🌐🖼️

@chartier But will it be JPEG XL or still HEIC? Or even downgraded to ancient Jpeg?

#JPEGXL #JXL #HEIC

FYI, if you use #Firefox you can now enable #JPEGXL support to try it out (without having to fiddle around with any tricky settings):

Just go to Settings > Firefox Labs > and enable the “Media: JPEG XL” checkbox.

It’s good to see that it’s another step closer to being enabled by default!

#Safari / #WebKit has had support for about three years (but doesn’t yet implement progressive loading), and #Chrome has it behind a feature flag, but not much has happened recently. Getting there, slowly!

The benefit of JXL not being recognized as an image format by signal is that you can just send JXLs via signal without it brutally compressing them in a lossy manner and stripping out all the exif data. 😊

#TIL about #jxl art: Hand-writing #JpegXL bitstreams to get a given image as small as possible.

This can apparently result in >90% reduction over the already chart-topping performance of the generic JXL encoder in some cases.

Insane stuff!

If you are using #Firefox 150 or higher remember to go into Settings and Block slopware interface in the “AI controls” tab, and to enable #JPEGXL in the Firefox Labs tab.

I happened to stumble across an article that JpegXL is now available in Chrome on Android (after a flag flip), and Firefox too. And indeed it is: https://jpegxl.info/resources/jpeg-xl-test-page.html

What changed? When?

#JpegXL #jxl

Dass es eine neue CSS-Eigenschaft (field-sizing) gibt, ist total an mir vorbei gegangen. Das muss ich dann einmal testen.

👍 :firedoge:

> Firefox [in version 152] now offers experimental support for the new JPEG XL image format, which generally provides better compression than WebP, JPEG, PNG, and GIF and is designed to supersede them.

Maybe someone can correct me, but wasn't #JPEGXL half deprecated because the browsers didn't want to support it just a year or two ago? This article makes it sound like #Google was pushing towards it and fully supporting it. Excited to see some love for it though.
