Preview is honestly such a good app. On top of everything else, it's also a very powerful PDF editor, which is something many companies built full paid products around — but on macOS you get it for free.
Preview, especially the .pdf editor, is probably the biggest feature I miss when using Windows instead of MacOS. I still don't get, how there isn't a comparable .pdf editor (that I know of) for Windows. The integrated one in Edge is fine for just reading things or highlighting something, but for adding notes, text or even just censoring things it is way worse than Preview.
