JPEG 's conspicuous issues like lack of transparency, animation, lossless compression and high bit depth support makes it little tough to justify it as leading format for time to come. Various attempts like WebP and AVIF are made (and are supported on modern browsers) to overcome problems of JPEG but they all also suffer some shortcomings of their own. Rather than discussing it, let's see how is the web finally going to change with this new format - JPEG-XL.

JPEG-XL is what we believe is next 20 year format. Why?

It's not one but multiple reasons.

60-70% smaller size compared to similar quality JPEG 😮 Dimension of upto billion pixels allowed (JPEG-XL exclusive) 4099 channels support (JPEG-XL exclusive) Animation support Tile support for large images Progressive decoding (see low resolution image first before full image loads - JPEG-XL and JPEG exclusive) Lossless encoding support Wide-color gamut support Extremely fast for both encoding and decoding (WebP and AVIF are much slower) Royalty free 🤘 This basically means anything that a photographer, developer or animation creator can think of, it's supported by this format. Everyone stays happy and gets to use one format for everything.

I would like to see JPEG-XL succeed. However, Google and Firefox have removed JPEG-XL support already so it will be very interesting to see what impact Apple's support will have. In the meantime, I'm using WEBP for my projects.

Firefox has jxl support in testing on beta builds. You need to flip the jxl flag in about:config.

JPEG-XL support is being tested in firefox nightly

I saw a av1 picture in the wild.
That was interesting experience as I assumed that's only a video file codec.

It's my first time hearing about JPEG-XL. What's the file format name? '*.jpeg-xl'?

Can I create it with Adobe Photoshop?

[–] [email protected] 20 points 1 year ago

I can only answer the first part: .jxl

[–] [email protected] 3 points 1 year ago

No clue about photoshop, but you can in GIMP, for whatever that is worth lol

No layer support? Or can that be faked by using 4 channel-chunks?

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (1 children)

Probably easier to fake with frames of animation, but JXL is not a replacement for .PSD or .XCF files and I do not know what usecase layers would be for besides authoring

In my company’s product, we allow users to place images into a composition and alter the colors (like tinting/colorize in Photoshop, so only globally). When doing that, the outline of the drawn image should not change color, and also there might be multiple color areas (think an image of a house where the walls have a separate color from the chimneys).

To do separate full-image manipulation, we need multiple layers. Right now they’re just a tilemap with the layers next to each other, but that doesn’t work for repeating patterns.
