Before you shareA watermark is visible, not secure

A watermark is visible, not secure. It's ordinary PDF content — text stays selectable and files stay small — so anyone with a PDF editor can remove it. Links, bookmarks, forms and metadata are kept.

It doesn't clean the PDF: scripts and other actions in it are kept as they are. A digital signature is invalidated, and a “fast web view” (linearized) file comes out without it.
