Welcome to the home of the PDF Power Tool.
This free tool will enable you to sign PDF files from a command line digitally. All you need to get started is a certificate and a PDF file.
If you don’t have an actual certificate, then we can help you create a test certificate you can use to test the functionality of our software.
