Signing a document with a graphical representation of your handwritten signature

  3. Select ‘Tools’> ‘Certificates’ > ‘Sign with digital signature’. A dialogue box with instructions to select a draw in the document will be displayed. Click ‘OK’ and draw a rectangle where you want the signature to appear.


  1. A new window opens. At the top, in ‘Sign as’, select your e-signature (with your first and last name, and CERTUM QCA inscription).
  2. Below, in ‘Style’, select ‘Graphical signature’ or ‘Default text’. Select ‘Block document after signing’ if you are the only or the last person to sign this document. Click ‘Signature’.

 The PDF document has just been given legal effect. The legal consequences of an electronic signature are the same as of a handwritten signature (the Act of 18.09.2001).
In addition, the file was saved under a different name than the original document. Thus, there are two documents: an e-signed document and a file without a signature.
