Mark and protect your documents

A watermark is a simple way to label a document's status (“DRAFT”, “CONFIDENTIAL”, “PAID”) or to discourage unauthorised reuse by stamping your name or company across the pages. PDFNest applies your text to every page with the size, colour, transparency and diagonal angle you set.

Because it runs in your browser, even sensitive contracts and internal reports stay completely private — nothing is uploaded.

Watermark PDF — FAQ

Can I make the watermark faint?

Yes. Lower the opacity value for a subtle background stamp, or raise it for a bold one.

Does it apply to every page?

Yes, the watermark is added to all pages of the document.

Can I choose the colour and angle?

Yes. Pick any colour and set the angle, for example 45° for a classic diagonal watermark.
