About the Add Watermark to PDF
PDF Watermark adds a diagonal text watermark to every page of a PDF. You choose the wording, font size, colour and opacity. Typical uses are marking documents as DRAFT, CONFIDENTIAL or COPY.
The watermark is drawn over each page at an angle, with transparency so the content below stays readable. A watermark deters casual reuse and makes the status of a document obvious, but it can be removed by determined people, so it is not a security feature.
How to use it
- Upload a PDF.
- Enter the watermark text.
- Set size, colour and opacity.
- Press Add watermark & download.
Tips and good to know
- Use low opacity so text underneath remains readable.
- Short words work best.
- Preview the output before sending.
