Set how many millimetres to trim from each edge. Cropping changes the visible page box; it does not stretch, resample or redraw what remains.

What crop means: The PDF CropBox becomes smaller. Content outside it is hidden from normal viewing, not rewritten or rescaled.
Exact units: Each edge is entered in millimetres and converted to PDF points at 72 points per inch.
Important boundary: Cropping is not redaction. Hidden content may remain in the file; use Redact PDF when information must be destroyed.

No. It changes the visible page boundary. Use the redaction tool when content must be destroyed rather than hidden.

Yes. The same edge margins are applied to each selected page's own current crop box.
