TIFFs are uncompressed or compressed with zip or lzw which is lossless. JPEGs are lossy and can't possibly be lossless. Pitting one as an alternative to the other is apples an oranges. When I read that sentence you quoted, I figured that the author is either lacking knowledge on the topic they're blogging about or they are trolling.

- tinus_hn 5y agoFile formats exist that have JPEG in the name, that have certain features JPEG does not, and that cannot be decoded by all of these programs that can decode JPEG files. A JPEG XL file, for all intents and purposes, is not a JPEG file. JPEG is a file format from decades ago. Obviously it’s possible to do better today. But it’s not possible to just invent a new format and have it as widely usable as JPEG. PNG did this with GIF but really only because GIF was seriously hobbled by software patents. It’s doubtful the millions of colors and alpha transparency would have won over compatibility otherwise.
- poizan42 5y agoTIFF is more like a container format that can contain a ton of different formats including many lossy formats. That also includes not just one but two different ways of embedding JPEG data (Compression 6 vs 7).
