Adding a watermark in Adobe Acrobat is a fairly simple process. First, select “Tools” from the top menu and then select “Edit PDF.”
The user will be taken back to their document, this time with an Edit PDF bar at the top. Select Watermark > Add.
A window will come up, allowing the user to adjust text, size, font, rotation, and other parameters. Once the settings are all in order, select OK and the watermark will be created.
