How to add a watermark to a PDF on iPhone

Before you begin

Choose wording that explains the document's status clearly. Keep the original when you may need a clean copy later, and consider whether the recipient requires a version without additional marks.

Step by step

1. Open the watermark tool in PDF Reader Pro.
2. Select the PDF and enter the watermark text.
3. Review the available appearance options and create the result.
4. Open several pages and check that the mark does not cover important information.

Check the result

Inspect dense pages, tables and signature fields. A watermark that works on a mostly blank cover can obscure content on a page with little empty space.

Limits and troubleshooting

Treat a watermark as a visible label rather than access control or proof of ownership. It does not securely redact text underneath, and sensitive material still needs an appropriate sharing and protection process.
