Frequently Asked Questions

Why can't my recipients sign the PDF I sent them?

If recipients cannot sign the document, the PDF might have security restrictions enabled. Ensure that 'Filling of form fields' and 'Signing' are permitted in the document's security properties before distributing.

Can recipients use a free PDF reader to sign the document?

Yes. Once you add a standard digital signature field, recipients can click and sign the document using free software like WPS PDF or Acrobat Reader.

How do I make the signature field mandatory?

When creating the signature field, right-click it to access its 'Properties'. Under the 'General' tab, check the 'Required' box to ensure the form cannot be submitted or completed without a signature.
