About watermarks
A watermark in a document is either text or an image that appears either in front of or behind existing content, akin to a stamp. For instance, you might use a "Confidential" watermark on sensitive data pages. Multiple watermarks can be added to one or more PDFs, each added individually. Also, you can just specify the pages or page ranges where each watermark should appear.
Unlike a stamp, a watermark becomes a fixed element within PDF pages. Stamps, on the other hand, are PDF comments that readers can open to view, edit, or delete text annotations.
Try it in the app
Add watermarks to PDFs for branding and document protection in a few simple steps.
-
Open the PDF to which you want to add a watermark.
-
From the global bar on the upper left, select Edit.
-
Under ADD CONTENT, select More and then select Watermark > Add.
-
In the Add Watermark dialog, adjust the source, appearance, and position as required. You can also save the settings for future use. Once you have set everything as required, select OK.
