PDF documents should be protected from any changes or manipulations. The attachment of a digital certificate by webPDF enables the possibility to digitally sign PDF documents. Thus the authenticity of the file is confirmed.
You can either sign a document via the webPDF.portal during the conversion or upload an existing PDF document for signing.
Using the multi-platform Java application webPDF.jclient you can digitally sign PDF files on your own computer by simply copying webPDF.jclient into any directory on your system without the need of an installation. There is a demo version available in our download area.
