A PDF is a container.
A PDF is a container for pages, fonts, images, links and document structure. A simple-looking edit can still affect more than the bit you can see in the thumbnail.

Useful to know
Four things worth knowing.
Opening is not the same as correct.
A PDF can open normally while page order, rotation, links, form fields, fonts or print quality are wrong.
Check the changed pages.
Open the downloaded PDF and scan the first page, last page, page order and anything you changed.
Keep the source document.
Keep the original PDF until the exported copy has survived the real handoff. For forms, signatures or records, do not overwrite your only source.
