By attaching a digital certificate webPDF is able to digitally sign PDF documents. Thus the authenticity (identification of the signer) of PDF documents can be confirmed and the documents are protected from changes or manipulation.
Use the webPDF.portal to digitally sign PDF documents during the file conversion or just upload an existing PDF file. You are also able to configure various settings such as the visibility or the position of the certificate.
The webPDF.jclient gives you the possibility to convert and digitally sign PDF documents on your own computer. The latest demo version is available in our download area.
