Seems to be just a rumor, but one that I hope is true. I also hope they use it as an opportunity to finally fix the longstanding ugly wart of having Live Photos be a separate .MOV file sitting alongside the HEIC file. JPEG XL is a container format so it should be possible to include the MOV as a separate box alongside the jxlc data and exif metadata. Of course, HEIF had the same capability and they still didn’t use i…

Technically they could already do this as JPEG allows adding arbitrary data to the file after the image data. ZIP files allow arbitrary data BEFORE the image data, therefore a file can be a valid JPEG and ZIP at the same time. So all you need to do is to put the MOV into a ZIP and append that to the image file, done. Live Photos in a single file!

Btw., you can abuse the „unlimited“ „free“ photos storage that comes with Amazon Prime that way.

is JPEG-XL really an upgrade over HEIC?

HEIC is paid, inferior, unpopular ... while JPEG XL is finally the long term replacement of ~30 year old JPEG.

Doubtful JPG will ever be replaced. It hits a sweet spot between implementation simplicity, (adjustable) visual fidelity, and ubiquity.

Even gifs persist because of they're grandfathered into auto play, despite being worse in every way than alternatives.

The JPEG-XL test page (linked in the article), works well. https://jpegxl.info/test-page/ At the bottom of the page it has animation demonstration, that doesn’t appear to work on my iPhone 13 Pro. Does JPEG-XL really include animation support?

macOS 14 / Safari 17.6 shows static pics, but no animation. Honestly, I wish all animated image formats would just die. They are an inefficient way to animate images, because they only use intra frames. H.264, H.265 or AV1 should be used for animations. Fortunately, Safari can display video files in or CSS images, which makes all animated image formats unnecessary.

Do you mean to say "even Safari"? Because there are quite a few people using other browsers.

Earlier quoted context omitted.

I can't imagine a PNG actually having a good compression ratio for photographic data. Better at that point to just shoot RAW.

Why not?

Because png compression is optimized for images with few distinct colors and long runs of the same color. Photographs are not like that.

I might make a website about this sort of stuff!

You may enjoy the https://pocorgtfo.hacke.rs/ zine where every release is a polyglot file. Some of the PDFs are bootable systems, some are NES cartridges, etc.

Section in the article: “The iPhone 16 family could let you shoot in JPEG-XL” I’m with you. No normal person is waiting for this. Are any techies? Like maybe 2? The article says the JPEG would be a third the size they are now. OK. That’s nice. But only 12.5% of Internet users can seem ‘em. All of ‘em Apple users. https://caniuse.com/?search=jpeg-xl So what’s the point? Just use HEIC. It’s supported by the exact same…

That's also significant $$$ when you're serving petabytes of image traffic every month. Even if it's limited to iOS.

That was indeed an inspiration for lab6.com.
