Similar to how you would apply a rubber stamp to a physical document, Adobe Acrobat allows you to place a digital stamp anywhere in your PDF file. The application includes in its library a set of default stamps, but you can also import images in a number of different formats to create your own custom stamps.

Step 1

Select "Comments" from the toolbar, and then choose "Add Stamp" from under Annotations.

Step 2

Point to "Custom Stamps," click "Create Custom Stamp," select "Browse," and then choose the appropriate format from the “Files of type” drop-down menu.

Step 3

Double-click the file to use, preview your stamp in the Sample pane, and then click "OK."

Step 4

Choose a category for the stamp, enter a name for the stamp, and then click "OK."
