About Watermark PDF
Draw configurable watermark text over each page with selected opacity, rotation, color, and font size.
Watermark PDF draws the same text across every page with adjustable size, opacity, rotation, and color. It creates a visible marking rather than a security or rights-management control.
How to use it
- Choose the PDF you want to mark.
- Enter the watermark text and adjust its size, opacity, angle, and color.
- Apply the watermark and download the marked copy.
Common use cases
- Mark a review copy as DRAFT or CONFIDENTIAL.
- Identify an internal or sample distribution.
- Add a visible status label before sharing a document.
Worked example
Apply a gray, 20%-opacity CONFIDENTIAL watermark diagonally across every page.
Limitations and responsible use
- A visible watermark can be removed by a determined editor and does not encrypt the document.
- Long text may extend outside small pages or overlap important content.
- Adding a watermark invalidates existing cryptographic signatures.
Frequently asked questions
Does a CONFIDENTIAL watermark prevent copying?
No. It communicates intent but does not enforce access control.
Are source pages rasterized?
No. The watermark is added as PDF text over the existing page content.
