Hi Adobe support, Greetings from SK Oilfields! Need support for working with signed pdf files, need to understand how to remove the signature and remove the certificates from a pdf file. Also, we expect to learn about how can we add certificates and signatures to pdf files. We have an Adobe Acrobat Pro DC licensed version. Please help. Thanks.

It is VITAL to make an archive copy before setting security or signing. You can't always go back. This is the most important lesson. That and how to be really, really organised with the archive copies.

Hi @JR Boulay ,

Isn't this the same article as the previous one?
Making myself more clear,
I need help with Editing Signed and Certified PDFs.
Also, I would like to know of how does Adobe Identify who is signing the PDF? ... This question comes to us because, we have one license for Adobe acrobat PRO DC which allows two users to use the software at two remote devices with the same account.
Now, if someone has signed using a digital signature(maybe that is when it shows signed and certified), the other user cannot edit it. Also we cannot remove the security as it says:

You cannot change security on this document because the document is signed or certified.
Please help.

You use a license of Adobe Acrobat for two users?

Yes, the regular one which allows two computers to use the license at once.

Hey @JR Boulay ,

Thanks, this partly helped.
I am still doubtful of how to remove the Certified-Signatures.
Also, how does Adobe identify that a PDF was signed by a user A when user B and A are using the same licensed account in Adobe Acrobat?
