Add PDF Watermark
About Add PDF Watermark
The Add Watermark to PDF tool lets you protect, brand, or mark your PDF documents by overlaying a text or image watermark on every page. Watermarks serve many practical purposes: marking documents as "DRAFT," "CONFIDENTIAL," or "COPY"; adding a company logo or copyright notice to branded materials; or indicating a document's status. Our tool gives you full control over the watermark's appearance — adjust the text content or upload a logo image, set the opacity level to make it subtle or prominent, rotate it diagonally across the page, and choose whether it appears on top of or behind existing content. All processing is done locally for total privacy.

Frequently Asked Questions
Is my document safe during watermarking?
Yes, all watermark processing happens locally on your computer in your browser. Your PDF document is never uploaded to any server. This is especially important for documents being watermarked precisely because they are confidential — you can safely watermark contracts, financial reports, and proprietary documents.
Can I remove a watermark that was added by this tool?
Watermarks added by this tool are embedded into the PDF page content. While they can be difficult to remove without specialized software, they are not designed as high-security DRM protection. For documents requiring strong access control, consider using our Protect PDF tool to add password encryption in addition to a visual watermark.
