How to Add Watermarks to PDFs — Branding, Protection & Confidential Stamps

Why Watermark PDFs?

Watermarks serve three purposes: branding (your company logo on every page), protection (discouraging unauthorized copying), and classification (DRAFT, CONFIDENTIAL, FOR REVIEW ONLY). A well-placed watermark communicates document status instantly and makes unauthorized distribution traceable.

How to Add a Text Watermark

1. Open the Watermark PDF tool
2. Upload your PDF
3. Enter your watermark text (e.g., "CONFIDENTIAL", "DRAFT", your company name)
4. Adjust opacity (30-50% for subtle, 70%+ for prominent), rotation, and position
5. Download the watermarked PDF

For formal legal stamps (CONFIDENTIAL, PRIVILEGED, ATTORNEY WORK PRODUCT), the Legal Stamp tool offers preset options.

Watermark Best Practices

• Branding watermarks — use 20-30% opacity, centered, subtle. Should be visible but not obstruct reading.
• DRAFT stamps — use 40-50% opacity, diagonal across the page. Must be obvious to prevent accidental use of draft versions.
• CONFIDENTIAL marks — use 30-40% opacity, header or footer position. Professional but clear.
• Copy protection — use the recipient's name or email as the watermark. If the document leaks, the source is traceable.

Complete Document Preparation

Watermarking is often the last step in document preparation:

1. Merge multiple files into one document
2. Add page numbers for reference
3. Add watermark for branding or classification
