> Visual quality, file size, compression time, decompression time, browser support, toolchain support, patent restrictions. Considering any one of those in isolation is insufficient for evaluating image formats.
Additionally, use cases are critical for understanding which of these and other properties matter, as well as their relative importance. Authoring formats (e.g. Apple ProRes, DNG) are evaluated much differently than distribution formats (e.g. AV1, JPEG).
And not to forget the third category: storage/archival formats. JPEG XL is unlikely to get widespread browser support, but that doesn't mean it isn't a good format to store high qualitiy originals. Either because they never touch a browser (my image viewer supports JXL) or because all images go through the resizing proxy anyways.
