How deal with ‘One of the documents is signed‘ error message?

I have a two documents that were signed electronically. I am trying to combine them into one single pdf document. Each time I try to drag one of the documents into the other I get the following error message..."one of the documents is signed". How can I combine these 2 docs?


Indeed, PDF Expert doesn't allow combining files if one of the documents has been signed. As a workaround, we recommend that you create a Flattened Copy of the forms which have signatures and then merge these copies.

To create a flattened copy of the document:

  1. Select File menu item
  2. Choose Save as Flatten...
  3. Change the name and location of the copy.
