Add Watermark to PDF

About This Tool

Adding a watermark to a PDF is one of the most effective ways to protect your documents from unauthorized sharing, duplication, or misuse. Whether you want to apply a “Confidential” tag, a company logo, a copyright notice, or a custom text stamp, this tool gives you an easy way to prepare documents for secure distribution.

Watermarks are widely used in businesses for branding, rights management, draft labeling, and proof distribution. This page provides the full user interface required for a complete PDF watermarking system. You can integrate backend processors, use WebAssembly PDF editors, or connect to cloud APIs to finalize the watermark application process.

For creators, freelancers, companies, or educators who share digital content, watermarking is a simple but powerful method of maintaining content ownership while still allowing easy access to your PDF materials.
