Why use PDF Watermarker?
Adding watermarks to PDF documents is essential for protecting intellectual property, branding documents, and marking confidential information. Whether you're a business owner sharing proposals, a photographer protecting your work, or a professional marking documents as drafts or confidential, watermarks provide a clear visual indicator of ownership and status.
Watermarks serve multiple important purposes. They protect your content from unauthorized use by clearly identifying the document's origin or status. For businesses, watermarks help maintain brand consistency across all documents while protecting sensitive information. For creative professionals, watermarks prevent unauthorized distribution of work while still allowing potential clients to preview content.
Traditional watermarking methods often require expensive software like Adobe Acrobat or complex online services that upload your files to their servers. This creates privacy concerns and potential security risks, especially when working with confidential documents. Our PDF Watermarker eliminates these concerns by processing everything locally in your browser, ensuring your documents never leave your computer.
Our tool supports both text and image watermarks, giving you flexibility in how you mark your documents. Text watermarks are perfect for adding labels like "CONFIDENTIAL", "DRAFT", or "SAMPLE", while image watermarks allow you to add logos or custom graphics. You can control the position, opacity, and size of your watermarks to achieve the perfect look without obscuring the document's content.
The watermarking process is fast and efficient, applying watermarks to all pages of your PDF simultaneously. This saves significant time compared to manually watermarking each page in traditional software. The watermarks are embedded directly into the PDF, making them part of the document structure and ensuring they appear consistently across different PDF viewers.

Frequently Asked Questions
Is my PDF file secure during watermarking?
Absolutely. All watermarking happens entirely in your browser using client-side JavaScript. Your PDF file never leaves your device, never gets uploaded to our servers, and we cannot see or access any of your documents. This ensures complete privacy and security.
Can I remove watermarks after applying them?
Watermarks applied with our tool become part of the PDF document structure. While they can be difficult to remove completely, it is possible with advanced PDF editing software. For maximum protection, consider using PDF encryption in addition to watermarks.
What image formats are supported for image watermarks?
Our tool supports common image formats including PNG and JPG/JPEG. PNG format is recommended for watermarks with transparency, while JPG works well for photographic watermarks.
Can I apply watermarks to specific pages only?
Currently, our tool applies watermarks to all pages of the PDF. This ensures consistent protection and branding throughout the document. If you need page-specific watermarks, you can split your PDF first, apply different watermarks, and then merge them back together.
