Webp's lossy mode may be uninspiring, but it also has a good lossless mode and supported both lossy and lossless transparency.

- ZeroGravitas 4y agoWorth noting that JPEG XL has a pretty good lossless mode too, however, I think in many cases you actually want to just use a lossy AVIF or JPEG XL in places you'd previously have used "lossless". It was kind of an artificial split, much like text, alpha transparency or line drawing might be done as PNG, not because you wanted them to be "lossless" but because JPEG would mess them up due to a lack of tools for reproducing non-natural photo content.

- JyrkiAlakuijala 4y agodon't look there -- that 'lossless' comparison is not actually lossless here, a better comparison: https://siipo.la/blog/whats-the-best-lossless-image-format-comparing-png-webp-avif-and-jpeg-xl https://siipo.la/blog/whats-the-best-lossless-image-format-c... this one is also good: https://www.reddit.com/r/AV1/comments/fjddcj/lossless_image_formats_comparison_webp_jpeg_xl/ https://www.reddit.com/r/AV1/comments/fjddcj/lossless_image_... basically: JPEG XL does things right, WebP lossless is also not bad (14.8 % worse than JPEG XL), PNG is ok for its age (46.3 % worse), AVIF didn't focus on lossless (63.0 % worse)
