How to Add Watermarks to PDF Files
Watermarking PDF documents is essential for protecting intellectual property, marking drafts, and indicating document confidentiality. Our tool provides a live preview so you can see exactly how your watermark will appear.
Watermark Options
- Text: Enter any custom text like "CONFIDENTIAL", "DRAFT", or your company name
- Opacity: Adjust from 5% (barely visible) to 100% (fully opaque)
- Font Size: Range from 12pt to 120pt for small labels or full-page stamps
- Color: Choose from preset colors to match your branding
- Position: Place at center, any corner, or diagonally across pages
Common Watermark Uses
Mark documents as "DRAFT" during review cycles, add "CONFIDENTIAL" to sensitive files, stamp "COPY" on distributed documents, or add your company name for branding purposes.
Best Practices
For readability, use 20-40% opacity with a diagonal position. This ensures the watermark is visible without obscuring document content. For stronger protection, increase opacity to 50% or more.
