> Subjectively, I'd say WebP and the newer AVIF or HEIF does a better job than Jpeg (to my eyes). However, I could see why others might disagree. They can do great with a clean original. But with an original that was already carefully mastered in JPEG format, with quality set to the bare minimum to get a good output... well, lossy compression is lossy, and when there isn't any margin for more loss, the results won't be good. (It's also true that since different lossy algorithms are, well, different, the interaction of two algorithms can be truly awful to look at). Unfortunately, there are very few image editing pipelines which let one master in anything other than JPEG, PNG, or GIF.
