Isn't Preview limited to just annotations, or does it also do editing?

Aside from annotating, Preview can crop, reorder, rotate, delete, and insert pages in a PDF.

But at its core, it does not "non-destructively" edit the dictionaries and object graph of the original PDF. Instead, it replays the original PDF into a new PDF context.
