How to Create a Watermark on a PDF
A PDF watermark is image or text that you can add to the background or foreground of your PDF document. You can use watermarks for various purposes, such as marking a document as "Confidential" or branding documents with a corporate name or logo. With Adobe Acrobat, you can insert images or text to use as a watermark. With CutePDF Professional, you can use an image stamp as a watermark.
