The most flexible way to add watermarks to PDF documents
Add text watermarks like 'DRAFT', 'CONFIDENTIAL', or 'SAMPLE', or upload your company logo as an image watermark. Both types support full customization of size, color, and positioning.
Place watermarks in any corner, center, or along the diagonal. Use the tile option to repeat watermarks across the entire page for maximum coverage and protection.
Adjust transparency from invisible to fully opaque. Rotate watermarks to any angle—diagonal watermarks at 45° are popular for document protection while remaining readable.
Your PDF files never leave your device. All watermarking happens locally in your browser using WebAssembly. We cannot see your documents or watermark content.
Apply the same watermark to up to 100 PDFs simultaneously. Perfect for adding company logos to multiple documents or marking an entire folder as confidential.
No subscription, no limits, no registration required. Watermark unlimited PDFs with full features at no cost. No additional watermarks added by us.
Common scenarios where watermarks protect and brand your documents
Add copyright notices or ownership watermarks to prevent unauthorized use of your documents. Watermarks make it clear who created or owns the content.
Example: Add '© 2024 Your Company' watermark to prevent document theft
Mark documents as DRAFT, CONFIDENTIAL, APPROVED, SAMPLE, or DO NOT COPY. Prevent confusion about document versions and ensure proper handling.
Example: Mark contract drafts as 'DRAFT - NOT FOR EXECUTION'
Add your company logo to all outgoing documents. Maintain brand consistency and professional appearance across all PDF communications.
Example: Add corporate logo to proposals, quotes, and reports
Mark preview documents as samples to prevent unauthorized final use. Design agencies often watermark proofs until final payment.
Example: Watermark photo proofs or design mockups with 'SAMPLE'
Add case numbers, dates, or identifying marks to legal documents. Ensure proper tracking and identification of court filings.
Example: Add case number watermark to all documents in a legal matter
Mark internal-only documents to prevent external distribution. Add 'INTERNAL USE ONLY' to sensitive company documents.
Example: Watermark HR documents and internal policies

Expert techniques for effective document watermarking
Diagonal watermarks at 45° are harder to crop out and cover more of the page while remaining readable. They're the standard for DRAFT and CONFIDENTIAL markings.
Use 30-50% opacity for watermarks over text-heavy documents. Lower opacity ensures content remains readable. Use 70-100% for image-based documents or when visibility is paramount.
Use the tile/repeat option to cover the entire page with watermarks. This makes it virtually impossible to remove or crop out watermarks from stolen documents.
For image watermarks, use PNG files with transparent backgrounds. This allows your logo to overlay content naturally without white boxes around it.
Bottom-right watermarks are subtle for branding. Center watermarks are prominent for status marking. Corner watermarks are less intrusive for multiple-page documents.
Watermarks are permanent—they cannot be removed. Always keep unwatermarked originals in a secure location for future use without the watermark.
