What this watermark pdf does
Watermark PDF draws text such as CONFIDENTIAL or DRAFT across each page. A centred diagonal watermark is the usual choice; a tiled pattern resists cropping better but can obscure more of the page.
The watermark is real PDF text, so it prints and travels with the file. It is a visual label, not access control: anyone who can open the PDF can cover or remove it. Use redaction when the goal is to remove information.
Why use it
- Mark draft or internal documents before sharing.
- Add a visible confidentiality warning to printed copies.
- Label sample files sent to clients.
How to use it
- 1Open the PDF.
- 2Enter the text, size, colour and opacity.
- 3Choose centred or tiled and download the watermarked copy.

Common mistakes

- Assuming a watermark prevents copying or editing.
- Choosing a colour with poor contrast against a dark page.
Frequently asked questions
Can the watermark be removed?
Yes. Anyone with a PDF editor can remove or cover it. Watermarks deter casual sharing; they do not enforce anything.
Does it work on scanned PDFs?
Yes. The watermark is drawn on top of the page, whether the content is text or an image.
Can I add an image watermark?
This tool supports text only. A logo watermark would need a PDF editor with image placement.
