Why can't I edit a PDF after signing?
When you sign a PDF using your digital ID, the PDF becomes read-only for others. If you received a PDF digitally signed by others, you can sign it, but can't edit it. While signing a PDF, if the signer chooses to lock the document after signing, the document becomes read-only for everyone, including the signer.
How do I edit a PDF after signing?
If you are the owner of the digital certificate used to sign the document and the document wasn't locked when signed, you can open the Signatures' pane at the left and right-click on the signature to clear it. After that, if the PDF document is a form, you can clear or edit its fields.
How do you sign a PDF that has already been signed?
Open a PDF that contains multiple signature fields.
Right-click the first signature field to be signed and choose to Certify with Visible Signature option.
The Certify Document window will appear.
Click Sign.
Save the PDF & enter the password for your Certificate/USB Token.
