JPEG XL could let you pack twice as many photos into your phone

This is making me think of JPEG 2000

https://en.wikipedia.org/wiki/JPEG_2000

A JPEG standard which never really took off... Why would this one take off when there are so many other alternatives now?

I think the problem is for cameras JPEG is good enough for most people, and the small percentage of people who do care will take photos in RAW format.

I remember hearing about JPEG 2000 when they were working on it. Of course it was marketed to be the ultimate image compression. I've only see it used once in the wild, I think it was Trillian that used to for screen captures.

The frame encoder for AV1 would blow away anything we have now but there isn't a push to use it on images unfortunately.

HN tends to dislike abuses of JS but one of the coolest polyfills I've seen tricks browsers into using their video decoders to render WebP and other more modern image formats. Definitely worth looking into if you've got a lot of huge images

The article mentions AVIF.

Although a better format is much welcome the only reason phone storage is an issue is because it's one of the few features that you can charge extra for.

Wow. The example images displaying results of the different compression formats are JPEGs.
