Stamp text such as DRAFT or CONFIDENTIAL across every PDF page.
About the PDF Watermark
The Freemium.Tools PDF watermark tool stamps text such as DRAFT or CONFIDENTIAL across every page of a PDF, with layout, colour and opacity controls, all inside your browser.
Marking a document as a draft, an internal copy or a specific recipient's copy stops the wrong version being circulated as final.
Choose a diagonal stamp, a straight line across the middle, a tiled pattern or a discreet footer. Because the file is processed locally, even confidential documents stay on your machine.
How to use it
- 1Type the text. Enter the wording, for example CONFIDENTIAL or a recipient's name.
- 2Choose the layout. Diagonal, centred, tiled or a small footer line, then set colour, size and opacity.
- 3Add your PDF. Drop the document in; every page is stamped on your device.
- 4Download. Save the watermarked PDF.
Frequently asked questions
Can the watermark be removed?
It is drawn into each page's content, so it cannot be toggled off in a reader. A determined editor with professional software could still remove it, so treat it as a clear marking rather than security.
What opacity works best?
Around 10-20% for a large diagonal stamp keeps the text underneath readable while the marking stays obvious.
Does it work on scanned PDFs?
Yes. The stamp is drawn over whatever the page contains, including scanned images.
Is my document uploaded?
No. The PDF is opened and rewritten inside your browser, so confidential files never leave your device.
