Practical guide

When and how to use Add Watermark

Add Watermark places repeated visible text over PDF pages. Watermarks can communicate draft status, confidentiality, ownership, or a review stage without changing the source file.

A watermark is a visual notice, not access control. Anyone who receives the file can still open it unless separate encryption is applied.

Best used for

  • Marking a document as draft
  • Adding a confidential notice
  • Identifying review or sample copies

Quality checklist

  • Use enough contrast to remain visible
  • Avoid covering signatures and essential text
  • Check every page before distribution
