  • On the screenshot example, the brightness of the white changes a lot between avif and lossless (especially noticeable on the underline for links). There is a similar effect on the shine in the woman’s glasses on the People picture. It might be something to do with the scaling algorithm (on 1080p, the image is shrinked quite a bit), but it doesn’t happen to the jxl images (which look exactly like the lossless ones to me). … aaand I just realized I’m on firefox 157, which doesn’t have native jxl support, so I’m just comparing scaling algorithms between a js-drawn canvas and real avif. After trying on 158, there is no such effect. It would be nice to get a link to open the full image in a new tab, to be able to compare the lossless to the lossy without being constrained by the website layout.
