What is PDF Watermarking?
PDF watermarking is the process of adding text or images to PDF documents that appear behind or over the content. Watermarks can be used for branding, copyright protection, document classification, or to indicate document status (such as "DRAFT" or "CONFIDENTIAL"). A PDF watermark tool simplifies this process, enabling you to add professional watermarks with just a few clicks.
Why Add Watermarks to PDF Files?
1. Document Protection
Adding watermarks to PDFs helps protect your intellectual property and prevents unauthorized use. Watermarks make it clear that the document is copyrighted or confidential.
2. Professional Branding
Add your company logo or branding to PDF documents to create a professional appearance and reinforce brand identity across all your documents.
3. Document Classification
Use watermarks to classify documents as "CONFIDENTIAL", "DRAFT", "FOR REVIEW", or other status indicators that help recipients understand the document's importance or status.
4. Copyright Protection
Watermarking PDF files helps establish ownership and copyright, making it more difficult for others to claim your work as their own.
5. Document Tracking
Watermarks can include tracking information, version numbers, or timestamps that help you manage and track document versions.

- Consider document layout when choosing position
3. Text Watermark Best Practices
- Use clear, readable fonts
- Keep text concise (1-3 words work best)
- Choose colors that contrast with document background
- Consider rotation for diagonal watermarks
4. Image Watermark Best Practices
- Use high-quality images with transparent backgrounds (PNG)
- Adjust scale to fit document size appropriately
- Ensure logo is visible but not overwhelming
- Test different sizes to find optimal appearance
5. Rotation for Professional Look
- -45° rotation is popular for text watermarks
