Simple digital signatures and image-based signatures can often be removed with PDF editors, while advanced or qualified digital signatures are encrypted and non-removable.

Methods to remove signatures include undoing recent signatures, deleting from editable PDFs, converting PDFs to editable formats, and flattening/redacting documents.

Digital signatures are electronic data transferred to an online document that proves someone’s intention to sign it. There are three types of digital signatures—

Alternatively, you can delete simple signatures from documents someone else has signed using editing tools, such as PDF.net.

In contrast, if someone sends a signed document, especially one with an advanced or qualified signature, it will be impossible to remove PDF digital signatures

4 Methods for Removing a Signature From a PDF
