You 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.
