Add Watermark

A watermark tells everyone at a glance how a document should be treated — DRAFT, CONFIDENTIAL, or your company name across each page. Add Watermark overlays your chosen text onto every page of a PDF, helping you mark ownership, flag a document's status, or discourage unauthorised reuse of your work.

It is especially useful when circulating drafts for review, sharing proofs with clients, or protecting original material you are sending out for feedback.

Upload your PDF, enter the text you want, and download the marked document with the watermark applied consistently across the pages.

Keep the wording short. A watermark is read at a glance rather than studied, and a long phrase becomes small, cramped and illegible across a page. Single words work best — DRAFT, CONFIDENTIAL, SPECIMEN, COPY — or a short phrase such as 'Not for distribution'.

Be specific where specificity helps. 'DRAFT — not for circulation' communicates considerably more than 'DRAFT' alone, and a version or date marker such as 'DRAFT v3, August 2026' prevents the common problem of an old draft resurfacing months later with nobody able to tell which version they are holding.

A watermark has two jobs that pull against each other: it must be obvious enough to notice, and faint enough to read through. Too subtle and people miss it entirely, which defeats the purpose on a confidential document. Too heavy and the underlying text becomes genuinely hard to read, which is a real accessibility problem as well as an annoyance.

Check the result on the busiest page rather than the emptiest one. A watermark that sits comfortably over a title page can be unreadable over a dense table.

Consider printing too, if the document might be printed. A light grey watermark that reads well on screen can vanish entirely on paper, and a heavy one can consume a surprising amount of toner across a long document.

Watermarks communicate status and ownership. Marking a document CONFIDENTIAL puts every recipient on notice about how it should be handled, which has practical and sometimes evidential value if it is later shared inappropriately. Marking drafts prevents the familiar situation where an unapproved version gets treated as final.

What a watermark does not do is prevent copying. It is an overlay on the page, not a protection mechanism, and text underneath remains fully selectable and extractable. Someone determined to reuse the content is not meaningfully impeded.

It also does not conceal anything. If information on the page should not be visible to the recipient, a watermark over it is not a solution — that requires redaction, which removes the content rather than covering it.

Watermarking happens in your browser and the document is not uploaded. This suits what the tool is usually for: documents marked CONFIDENTIAL or DRAFT are, by definition, ones you have already decided need careful handling, and routing them through a third-party server on the way to being marked confidential would be an odd sequence of events.
