ABOUT PDF WATERMARK

The PDF Watermark Tool adds text watermarks to PDF documents entirely in your browser using PDF-lib. Watermarking PDFs is standard professional and legal practice — marking document status (DRAFT, CONFIDENTIAL, APPROVED), protecting proprietary content, and branding shared reports.

Common use cases: marking contracts as DRAFT before final review, labelling confidential reports, stamping SAMPLE on template previews, and branding study materials or business reports with company name before sharing.

Documents are never uploaded to external servers — critical for sensitive business and legal documents.

// Use Cases

WHEN TO WATERMARK

// Tips

TIPS
