How JPEG XL Compares to Other Image Codecs
JPEG-XL is the next-generation royalty-free image format. Specifically designed to deliver visually indistinguishable compressed images, JXL is over 60% more efficient than JPEG and much better at retaining detail for high-fidelity images than video-codec-based WebP, AVIF and HEIC. In terms of decoding speed, JXL can be decoded nearly 10x faster than HEIC and more than 20% faster than JPEG.
JXL is an image format of mind-numbingly large numbers. Each JXL image can be more than 1 trillion megapixels in resolution — while supporting progressive decoding and without grid boundaries. Each pixel supports 32-bit colour — 32 bits per channel, for up to 4100 channels (4 of which are reserved for R, G, B, A). In other words, a JXL image can represent up to 300 undecillion colours. By the time these specs need an upgrade, we would hopefully have moved on to holograms.
Safari, macOS Quick Look, many professional artists’ tools and now the Gnome ecosystem support JXL. On this note, I’ll go back to waiting for Chrome and Firefox.
I’ve always thought JPEG-XL is an incredible standard, and I have no idea why it’s taking so long for platforms to adopt it. Glad GNOME finally does. Thanks for this informative write up!
Chrome had jxl support but google dropped it. https://www.cnet.com/tech/computing/chrome-banishes-jpeg-xl-photo-format-that-could-save-phone-space/ it’ll take long until google bringa back jxl, if ever. As long as google doesn’t support jxl, jxl is going to have a difficult future
Chrome recently abandoned its experimental support for JPEG-XL
I think we(as in GNOME users) don’t care, the format is to great to not use it.
This is a great step in the right direction. The more formats a software supports, the bigger the value of said software.
Wow that awesome. Why did I never know about this
Is .jxl pronounced “jaxel” or “jexel”?
It’s pronounced “Junkie XL” link

Woot. First Safari, now Gnome is supporting it. We’re gonna get there. Screw webp.
for the weird nerds like me:
1,000,000,000,000 (1 trillion) megapixels is:
1,000,000 (1 million) terapixels
1,000 petapixels (note: petapixel is a pretty cool photography site)
1 exapixel
1,073,741,824² pixels is exactly 1 exbipixel (EiP).
