What does cropping a PDF do?

Accepted Answer

Cropping adjusts the visible page boundaries by trimming margins. This is useful for removing whitespace, preparing for print, or fitting content to specific paper sizes.

No. Cropping adjusts the MediaBox and CropBox of each page, which tells PDF readers which part of the page to display. The original content is preserved but hidden.
