What is Add Watermark?
PDF Watermark overlays text (such as "CONFIDENTIAL", "DRAFT", or "COPY") onto every page of a PDF — a standard practice for marking document status or ownership.
When to use this tool
- Marking a document as "DRAFT" or "CONFIDENTIAL"
- Adding a copyright notice to every page
- Overlaying a "SAMPLE" watermark on preview documents
- Branding documents with a company name
How it works
Uses pdf-lib to render a large, semi-transparent text element centered on each page. Configurable options include text content, font size, opacity, rotation angle, and color.
Security Guidelines
- Watermarks are visual overlays only — they do not prevent text extraction or copying
- For true document protection, combine with password protection
Examples
Draft watermark
Input: proposal.pdf
Output: proposal.pdf with "DRAFT" watermark on every page
