Watermark PDF: what it is and when to use it

Protect your documents with a watermark such as "CONFIDENTIAL" or your name.

A watermark is text, such as "Confidential" or "Draft", that appears across every page of the PDF. It is used to indicate a document's status or discourage misuse.

With Rayo PDF GO you type the text, adjust the opacity, and apply it to the whole document on your device.

Common uses

Mark contracts as draft or confidential.
Identify copies given to a client.
Flag documents for internal use.
Protect business proposals.

Tips for better results

Low opacity keeps the content readable.
Use short, clear text.
Keep the original without the watermark.
