Set your watermark text, "DRAFT," "CONFIDENTIAL," a name, a date, and drop your PDF above. A semi-transparent stamp is drawn diagonally across every page, then the file downloads automatically once ready.

A visible watermark is a signal, not a lock: it makes a document's status obvious at a glance and discourages someone from passing it off as final, but it doesn't stop anyone from opening, copying, or printing the file.

FAQ

Can I remove the watermark later?
Not with this tool. The watermark becomes a permanent part of the page content, drawn directly onto each page.
Is this the same as password protection?
No. A visible watermark discourages casual reuse and marks a document as a draft, confidential, or otherwise, but it doesn't restrict who can open, copy, or edit the file. It's not access control or encryption.
Is the watermark added to every page?
Yes, at the same position, size, and opacity on every page in the document.
