Why watermark a PDF?
- Marking drafts before final approval
- Labelling confidential documents
- Discouraging re-use of shared work
Limitations
Watermarks use a standard font that supports Latin characters. A text watermark can be removed by someone with PDF editing software — it's a label, not security.
