Add a text watermark to a PDF
A text watermark stamps a word or short phrase across your pages — "DRAFT", "SAMPLE", a company name, or "DO NOT COPY" — so the document's status or ownership is clear at a glance, even on a printout or screenshot. Type your own text below and tune how it looks: font size, opacity so it sits behind your content without making it unreadable, and the rotation angle for the familiar diagonal stamp. The watermark is applied to every page automatically and saved into the file as real text laid over the content, so it shows in any viewer and when printed. Because it is semi-transparent by default, the underlying text stays legible while the mark is unmistakable. The whole job runs in your browser, so the PDF is never uploaded. It is free, needs no signup, and there is no second watermark added by the tool itself.
Frequently asked questions
- Can I use my own watermark text?
- Yes. Type any word or phrase, then adjust its size, opacity and angle before applying it to every page.
- Will the watermark make my content unreadable?
- No. It is semi-transparent by default and you can lower the opacity further, so your content stays legible beneath it.
