Save document changes
If you modify a PDF—such as by adding new pages from another file or deleting pages—you can save your changes by saving the PDF or by saving a copy of the PDF. You can also save changes to your work incrementally and then recover those changes if a problem occurs.
Note: Saving a digitally signed PDF invalidates
the signature.
