Originally posted by TheLexMachine View PostJPEG-XL can easily be supported in advanced post-processing software and image viewers - where it belongs - as an HQ archival/presentation format for "finished" images created from RAW files. It will have no place as an in-camera file output format, because the camera companies that dominate the consumer and professional market (Sony, Canon, Nikon, Olympus, and Fuji) won't use a standardized replacement for their proprietary image processing with secret-sauce-filled RAW formats, something which had already been tried (Adobe DNG) in the early days of mass-adopted digital photography.
JXL is IMO will quickly become the only viable image format for these kinds of picture taking in the future for quite some time to come.

Is there any way someone could add it back through an add-on?

Not really: JPEG-XL stores jpeg files (on average) using less space than the originals, while producing bit-for-bit identical copies of the resultant image when expanded. This is useful when you are storing lots of jpeg files: it can save you monetarily significant amounts of space. Cameras don't have to support JPEG-XL for it to be useful.

Originally posted by quikee View PostLossy WebP is also limited to 4:2:0 only, which is IMHO a worse limitation than just being limited to 8-bit as even JPEG has 4:4:4 mode. Also isn't WebP using TV range YCrCb colorspace (same as JPEG), which is in reality only about 6.5 bit per channel...
Originally posted by OneTimeShot View PostI think the problem with JPEG-XL is the patent status (in particular the ones owned by Microsoft) rather than any malfeasance by Google.
I am always wary of new formats though, so I may be worried unnecessarily. JPEG and PNG are patent free, and we should only move to other patent free formats (especially if it only saves 50% disk space and has no other real advantages that normal people care about)

I wish for three things:
1. Some major browser enabling JPEG XL by default, whether it's Firefox, Safari or Edge doesn't even matter. (So far only Pale Moon and Waterfox support JXL).
2. Some major websites with lots of pictures - maybe Facebook, Instagram, Twitter? - to use JXL with a polyfill script to convert it to JPG for unsupported browsers. Ideally with a banner warning that "Chrome is not supported" or something.
3. Camera and smartphone makers (Samsung? Xiaomi?) using JXL as the default format rather than JPEG like now.
