Use this page to add watermark to PDF pages as a diagonal line of text, such as Confidential. The stamp is text, not a picture.
Files stay on this device. Nothing is uploaded.
The text sits on top of the page at an angle and scales with the page size, so a wide sheet and a tall sheet both get a readable mark. Pick wording that will still make sense if someone prints a single page from the file.
A stamp is not a lock. Someone with a PDF editor can remove it. If you need a file that will not open without a password, use the lock tool instead.

fill a PDF form
Fill in a PDF form on this device, tick checkboxes, and flatten if you want the answers locked in.
