Add Watermark to PDF
Stamp a text watermark or page numbers onto a PDF — never uploaded.
Add watermark to pdf free, directly in your browser. Choose a PDF, set the watermark text or mark you want, and download a copy with the watermark applied to the pages. People use this to label a document as a draft or confidential, to mark a file as a copy, or to add a name or company label before sending a contract or report to someone else. Because the work happens locally, your PDF is never uploaded to a server, which suits private files such as invoices, ID scans, and legal papers. You do not need Adobe Acrobat, Preview on a Mac, or a desktop program, and there is no account to create. It works on Windows, Mac, Linux, and phones with a modern browser, and it keeps working offline once the page has loaded. If you only need to stamp a few pages of a document quickly, this is a lightweight way to add watermark to pdf online without handing the file to a third-party service.
