Thanks for the iPhone hint! Do you happen to know or have an idea why Apple chose to offer JPEG XL only as ProRaw format? For “normal” photo capture, they still use HEIC only.
For all I know, the 4K thing is misinformation.
Oh wow, Mozilla reconsidered JXL support. They said no after Google pulled out, but “now” (well, since an entire year ago) they’re at half a yes again.

Edit: neat, it has recently landed in the Firefox codebase: https://phabricator.services.mozilla.com/D263393
Still behind a flag, but Apple seems to have decided for JXL, and Mozilla seems to have gotten their mind made up and following suit.
Glad to hear JPEG-XL is still making its way. It deserves to become the most widespread image format.
Regarding web usage after the Google situation:
I do disagree about AV1. Its AVIF image format spinoff is very good. Often better quality or smaller file size than webp, and has browser support as good as webp nowadays. And of course,
I work on a lot of web projects, and I used to serve webp and AVIF for a while (based on the browser’s HTTP Accept header). Recently, I decommissioned all webp handling and serving code.
See https://caniuse.com/?search=image+format. You can serve an AVIF for every requested JPEG or PNG file.
Correct! And not just the charger and the device, also the cable needs to have the right e-marker chip (> 5 A), speak the protocol and confirm that it can carry the requested current during negotiation.
Just look at this teardown. High-current USB-PD cables are electronic devices of their own right: https://www.chargerlab.com/teardown-of-apple-240w-usb-c-charge-cable-a2794/
Forget webp. AVIF is the image format.
(Especially after Google killed JPEG-XL.)
Let me introduce you to the magic of USB Power Delivery, an incredible standard that brought forth USB-C devices that can’t work at all with USB-C chargers, since they don’t speak the required protocol.
Slow charging is compatibility mode. That’s a tad better than not working at all.
Yay to the USB standards bodies, and the many non-standards implementers, I guess.
Makes sense. Thanks for your knowledgeable response!
