Adding watermarks to PDF documents is an essential practice for businesses, creatives, and professionals who need to protect their intellectual property, mark document status, or simply brand their materials.

What is a PDF Watermark?
A PDF watermark is a visible overlay of text or image that appears behind or in front of the document content. Watermarks serve multiple purposes:
- Identifying document status (Draft, Confidential, Approved)
- Protecting intellectual property (Copyright notices)
- Branding documents with logos or company names
- Preventing unauthorized distribution
- Adding timestamps or version information

Common Use Cases for PDF Watermarks
Legal Documents
Law firms frequently use watermarks like "CONFIDENTIAL" or "DRAFT" to indicate document status and prevent unauthorized sharing. Watermarks can include case numbers or client identifiers.
Academic Papers
Researchers and students add watermarks to identify works in progress or to mark submitted assignments with their student ID numbers.
Business Proposals
Companies often include "COMPANY NAME - PROPRIETARY" watermarks on proposals to protect sensitive business information while still sharing documents with potential clients.
Photography Portfolios
Photographers use semi-transparent watermarks with their name or logo when sharing previews with clients to prevent unauthorized use of their images.
Architectural Plans
Construction documents often include "FOR REVIEW ONLY - NOT FOR CONSTRUCTION" watermarks during the approval process to prevent misuse of preliminary plans.

Some documents benefit from multiple watermark layers, such as:
