PDF Power Tool

Welcome to the home of the PDF Power Tool.

This tool is a free program that will enable you to digitally sign PDF files from a command line. All you need to get started is a certificate and a PDF file.

If you don’t have a real certificate then we can help you create a test certificate you can use to test the functionality of our software.
