Frequently Asked Questions

Why does my PDF say it cannot be signed in its current state?

This error typically occurs when a signature field has just been added but the document hasn't been saved yet. The software requires the new field to be committed to the file structure before it can be cryptographically signed.

Do I need Reader Extensions to add a digital signature?

If you are opening the file in a current version of a modern PDF reader, Reader Extensions are generally not required just to utilize or add a digital signature field.

How can I tell if a PDF is locked from being signed?

You can check the document's permissions by going to File > Properties, and then viewing the Security tab. If 'Signing' is marked as 'Not Allowed', the creator has locked the document.
