What is PDF Watermarking?
PDF watermarking is the process of adding visible text or images to PDF documents to indicate ownership, protect copyright, show document status, or add branding. Watermarks can be subtle or prominent, opaque or transparent, and positioned anywhere on the page.
Our advanced watermarking tool uses pdf-lib to add professional watermarks to your PDFs entirely in your browser. You can customize every aspect of the watermark including size, color, opacity, rotation, and position. Whether you need a "CONFIDENTIAL" stamp across your documents or a subtle company logo in the corner, our tool gives you complete control while maintaining full privacy since no files are uploaded to any server.
Common Use Cases
Document Security
Add "CONFIDENTIAL", "DRAFT", or "INTERNAL USE ONLY" watermarks to protect sensitive documents and indicate their status.
Brand Identity
Add your company logo or branding to proposals, invoices, and presentations to maintain consistent brand identity across all documents.
Copyright Protection
Protect your creative work by adding copyright notices or ownership information to prevent unauthorized use of your documents.
Frequently Asked Questions
Can I add a watermark to specific pages only?
Yes! You can choose to apply the watermark to all pages, first page only, or specify a custom range using formats like "1-5, 8, 10" to watermark specific pages.
What image formats are supported for watermarks?
We support PNG and JPEG image formats for watermarks. PNG is recommended if you need transparency support for your logo or watermark image.
Is my document safe and private?
Absolutely! All watermarking happens entirely in your browser. Your PDF never leaves your device and is not uploaded to any server, ensuring complete privacy and security.
What does the tile position do?
The tile position repeats your watermark across the entire page in a grid pattern, making it much harder to remove or crop out. This is ideal for protecting valuable documents from unauthorized use.
