Add a text watermark to every page
A watermark marks a document’s status and ownership at a glance — CONFIDENTIAL, DRAFT, a copyright line, or your own name across a shared file. Watermark PDF stamps your text diagonally (or at any angle) across every page of the document.
You control the wording, font size, colour, opacity and angle, so the mark is visible without hiding the content underneath.
Protect your work, privately
Watermarking is applied in your browser and your file is never uploaded, so you can mark sensitive drafts and proposals safely. There is no sign-up and no second watermark added by us.
Pair it with Add Page Numbers for professional-looking documents, or Protect PDF to lock the file with a password.
