Add a Watermark to PDF

Free Online PDF Watermark Tool

Adding a watermark is a quick way to mark a document as a draft, indicate confidentiality, or label a file as a sample before sharing it more widely. LovePDFImg's PDF Watermark tool stamps your chosen text across every page, with control over position, rotation, size, opacity, and color, so the watermark is visible without overwhelming the original content.

The watermark is drawn directly onto each page using your browser's JavaScript engine — the original text, images, and layout of your PDF remain completely intact underneath the new layer. As with all core tools here, your file is processed locally and never uploaded to a server.
