What Adobe Acrobat alternatives have PDF signing features [closed]
We use Adobe Acrobat at work for creating signed PDF documents. Currently run Adobe Acrobat 6 Professional to sign these documents. Acrobat Reader will not sign PDFs. Is there any non acrobat product that can:
- Sign PDFs
- Add signature fields to PDFs.
The first is more important than the second since I sign PDFs more than I insert signature fields in PDFs.
Solution 1:
OpenSignPdf is an open source project for the digital signature of PDF documents.
I'm not sure it this is a good idea, but there is experimental online PDF signing service.
Solution 2:
pdfMachine pro does digital signatures. They will also sell you a certificate if you want.
Solution 3:
Have you tried foxit reader and creator?
Solution 4:
jpdftweak, although I never tested signing with it.
If you want to do it from a program, look at iText.
