How to Add a Watermark to a PDF

A watermark stamps repeated text across every page — CONFIDENTIAL, DRAFT, a company name — so the status or ownership of a document is visible no matter which page someone is looking at, even if it's printed or a screenshot is taken of a single page out of context.

It's a labeling tool, not a security control: a watermark doesn't stop someone from reading, copying, or forwarding the document. For that, use Protect PDF's password encryption instead, or combine both when a draft needs to be clearly marked and access-restricted.

Upload the PDF, type the watermark text into the required field, and run Watermark. The text is stamped across every page at once — there's no per-page selection, since the point is consistent coverage throughout the document.

Keep it short — a couple of words reads clearly at any page size, while a long sentence repeated across every page becomes visual noise. Common choices are DRAFT during review, CONFIDENTIAL for restricted documents, or a company name for externally shared brand materials.
