A PDF watermark tool stamps a visible mark — text such as “CONFIDENTIAL” or “DRAFT”, or an image such as a company logo — across every page of a PDF. The mark is embedded directly into the page content, visible to all readers and deterring unauthorised distribution or copying.
PDF Watermark is a browser-based tool that lets you add text or image watermarks to every page. Choose PDF, use the controls above to configure the result, then download or use the resulting PDF.

A PDF watermark tool stamps a visible mark — text such as "CONFIDENTIAL" or "DRAFT", or an image such as a company logo — across every page of a PDF. The watermark is embedded directly into the page content, making it visible to all readers and deterring unauthorised distribution or copying.
Watermarks serve two main purposes: branding and document control. Branded proposals sent to clients carry your logo on every page. Internal drafts marked "DRAFT" or "NOT FOR DISTRIBUTION" signal their status clearly. EditPDF AI applies watermarks entirely in your browser, so the document never needs to be uploaded.
Common ways people use this tool in real documents and day-to-day workflows.
Add a logo or "SAMPLE" watermark to proof copies of artwork, photography, or design work shared with clients before final payment.
