alt Hacker NewsWhat percentage of the web is that 0.1% ? 0.01% ?
I think its correct to say a use case that is very niche on the web isn't super important to the web. Especially when there already exists a bunch of lossless formats. After all, the value proposition of jxl is to save some bytes. It would be different if the point was introducing images as a whole.
count .png-s in the web. There's a lot. And .jxl's lossless is much better than png's. Basically any image with sharp lines (screenshots, image of a button etc) or gradients should be lossless.
