Add a text watermark to PDF pages
Watermark PDF places visible text such as CONFIDENTIAL, DRAFT or another label onto PDF pages. A watermark can help communicate document status, ownership context or handling instructions while keeping the output as a PDF. The watermark is a document marking, not a password or permissions system.
A watermark does not prevent copying
Adding visible watermark text does not encrypt the PDF, restrict who can open it, provide digital-rights management or guarantee that content cannot be copied or edited with other software. Use it when a visible label is the goal. If the task is simply numbering pages, use Add Page Numbers to PDF instead.
Watermarking runs locally
The watermark operation is designed to process the selected PDF in your browser, so the file is not uploaded for this job. Enter the watermark text, generate the marked PDF and review the result before distributing the document.
