! By default only the page box changes; the content outside it is still stored in the file.
! Removing that content flattens every page to an image: the output is no longer searchable and grows larger.
! The same margins are applied to every page, even if page sizes differ.

How many points is a centimetre?

About 28.35 points, since a point is 1/72 of an inch.

Does cropping reduce file size?

The crop box alone does not. Removing the content does, at the cost of the text layer.

Can I crop just one page?

Not on this page; all pages receive the same margins.
