Questions
Why watermark a document?
To mark copies you send (e.g. "COPY" on a CNIC or degree scan for a job application), drafts, or confidential documents, so they can't easily be reused as originals.
Can the watermark be removed?
It's added as part of each page, so it can't simply be switched off, but anyone with PDF editing software could edit it. For sensitive documents, also share them only with people you trust.
