Question
I digitally signed a PDF, but I can't see the signature in the document?
Answer
When you use the SignFile function to add a digital signature to a PDF it adds an invisible digital signature which is not shown on any of the pages in the document. Instead the digital signature can be viewed by opening the PDF in Adobe Reader, Adobe Acrobat or another application like Nitro PDF Professional, and clicking on the Signatures tab which can usually be seen on the left-side of the application.
A screenshot demonstrating what a digital signatures looks like after it's been added to a PDF using Quick PDF Library can be seen below.
