"No permissions for this operation" for signed PDF

The PDF have signatures that must be "validated" before those can be edited.

That is why any batch editing fails. How to auto-validate such PDF?

i tried "Remove digital signatures", "Remove PDF standard" but all fails. Unfortunately, I cannot re-print the PDF as new plain PDF as the PDF printer does not use the source directory.

Hello, Knupps

They do not need to be validated before editing is allowed, they simply cannot be edited, because a signature exists. The validation notice is only present in the Editor becuase we do not immediately send for file validation upon opening the file. Completing that would not allow any additional editing capacity. This is intended when adhering to the PDF Specification.

The only way to edit these files will be to remove the signatures, doing that will require that the signature which was used has been installed locally to your windows system certificate store. If you do not have the certificate files, or the signatures were not placed by you, than you will need to find an older unsigned copy of the file to work with.

Kind regards,
