How to Add Watermarks and Confidential Stamps to PDF Documents
Protect intellectual property and copyright by stamping text watermarks or custom logos onto your pages.
Watermark Your PDF Pages
Apply custom text or logo stamps across all pages with full opacity and positioning control.
Why Use Watermarks on Business Documents?
Watermarks clearly communicate the status and confidentiality of documents. Stamping "CONFIDENTIAL", "INTERNAL USE ONLY", or "DRAFT - FOR REVIEW" prevents unauthorized distribution and keeps stakeholders aligned.
Photographers, publishers, and consultants also stamp subtle logos to protect copyright and prevent piracy.

Styling Watermarks for Maximum Protection
• Diagonal 45° Angle: Crossing diagonally across body paragraphs makes watermarks impossible to crop out without destroying the text.
• 15% - 25% Opacity: Keeps the underlying document legible while ensuring the stamp remains unmistakably visible.
