Sharing similar view. I even go as far as to say jpegli ( and the potential with XYB ICC ) makes JPEG XL just not quite good enough to be worth the effort.
The good thing is that the author of XL ( Jyrki's ) claims there are potential of 20-30% bitrate savings at the low end. So I hope JPEG XL encoder continues to improve.
- themerone 3y agoIt's not just about the compression ratio. JPEG XL improvements in generational loss are reason enough that it should be the default format for the web.
- JyrkiAlakuijala 3y agoYou can always use JPEG XL lossless JPEG1 recompression to get some savings in the high end quality, too — if you trust the quality decision heuristics in jpegli/guetzli/other jpeg encoder more than the JPEG XL encoder itself. We also provide a ~7000 lines-of-code libjxl-tiny that is more similar to jpeg encoders in complexity and coding approach, and a great starting point for building a hardware encoder.
- ksec 3y ago>JPEG XL lossless JPEG1 recompression This reminded of something. I so wish iOS 18 could support JPEG XL out of the box rather than Safari only. I have 80GB of Photos on my iPhone. Vast Majority of them were sent over by WhatsApp ( JPEG ). If iOS could simply recompress those into JPEG XL I would instantly gain ~10GB+ of storage.
- JyrkiAlakuijala 3y agoWhat happens if you recompress them losslessly manually to JPEG XL?
- spider-mario 3y agoThe Photos app supports JPEG XL as far as I’ve been able to tell.
- jug 3y agoYes, I agree and I think there is a hurdle in mucking with file formats alone because it always affects interoperability somewhere in the end. I think this also needs to be accounted for - the advantages need to outweigh this downside because it is a downside. I still kind of want JPEG XL but I'm starting to question how much of it is simply due to me being a geek that want tech as good as possible rather than a pragmatic view on this, and I didn't question this as much before Jpegli.
- JyrkiAlakuijala 3y agoIt can be a question when your uncle's/daughter's/etc phone is full of photos and they asks for advice on how to make more space. It can be a question of if the photo fits as an email attachment etc. 'Zillions' of seconds of aggregate latency waiting time is spent each day on waiting for web sites to load. Back-of-the-envelope calculations can suggest that the value of reducing waiting time can be in hundreds of billions over the whole time of the deployment. Bandwidth cost to users and energy use may also be significant factors.
