is JPEG-XL really an upgrade over HEIC?
One cool feature is that can losslessly convert JPEG into JPEG-XL. And back to JPEG. I can't tell if this applies to all or only converted ones, but it might make good source format and convert to JPEG on export.
JPEG-XL to JPEG is only lossless for JPEG-XL images which were upgraded from JPEG.
Not all JPEG-XL images can even be represented as JPEG; in particular, images with more than three channels (like images with transparency, or images with CMYK color) or with multiple frames (like an animation) certainly can't.
The old-JPEG-preserving compression mode also isn't the best that JXL can do. It's better than the old JPEG, but not as good as JXL using all the new bells and whistles.
But considering getting HEIC included in other system seems to be difficult due to patents or other reasons. JPEG-XL seems to be the best middle ground in everything.
I am still hoping there could be additional work on JXL in terms of low bit per pixel improvement and encoding / decoding resource usage. Especially in the lossless front.
Even gifs persist because of they're grandfathered into auto play, despite being worse in every way than alternatives.
And quality wise, JPEG XL is definitely better
Naturally, some types of images tend to compress better with some formats than others, and then you may have to take into account things like the desired quality level, encoding time, etc.

Realistically, any of those four new formats would be fine for 99% of the images that exist, but it would still be nice for every browser to support them all so that web developers can choose their favorite format.
Although, on the flip side, the drawback of having so many formats floating around is that software developers have to spend more time supporting it all. Even trillion dollar companies like Microsoft are seemingly in no rush to make sure that formats like WebP are as well integrated into their software as JPG/PNG were.
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.

So what’s the point? Just use HEIC. It’s supported by the exact same browsers. All Safari and nothing else.
This seems like a really sketchy rumor to me.
That's a positive for Apple. "Why can't I view the new family pics?" "Oh mom you need to get an iPhone for that"
That's also significant $$$ when you're serving petabytes of image traffic every month. Even if it's limited to iOS.
