I specifically meant automatic lossy compression with predictable visual quality. If ImageOptim could actually achieve it (automatically), that would save me and others an awful lot of time. But as it turns out it is not that easy.

Some very smart people at Google go to the trouble of creating projects like Guetzli. I personally have spent months on this, and it gets me every time someone claims "just use that one tool" without any evidence. I presented mine and it's reproducible.

ImageOptim is a great tool otherwise.
