If your organization needs to add text-based stamps to documents on a regular basis, Appligent’s StampPDF® Plug-in for Adobe® Acrobat® has the answer for consistency, quality, and cost-effectiveness.

The plug-in lets governmental organizations, corporations and law firms add page numbers, copyright notices, disclaimer statements, file names/numbers, Bates numbering, and more to existing PDF files.

Add one stamp or many stamps to PDF documents.  The stamps become a permanent part of the document.

StampPDF® Plug-in is available for Windows only.  StampPDF Plug-in 5.8 is compatible under Acrobat XI, DC and 2017. StampPDF® Plug-in 5.6 is compatible under Adobe Acrobat X and XI.  It does not work with the free Adobe Reader.

If your organization requires dynamic stamping or batch stamping of PDF files, check out StampPDF Batch, our Server-based software application for adding content to existing PDF files.

How to Use StampPDF Plug-in

Frequently Asked Questions

Q:  How do you create a Bates stamp?

A:  In StampPDF Plug-in, Bates numbering works similarly to regular page numbering. The variable used for Bates numbering is %J. If you would like to start numbering at a number other than 000001, place the number to start before the J. Learn more about working with StampPDF variables.

Q:  How do I remove the old page numbers and re-apply new page numbers to my PDF?

A:  You can set up your stamp file to apply a white jpeg image over the area that contains the old number and also have a stamp item to apply the new page numbers. Learn more about using StampPDF Plug-in.
