This is very useful for letters and contracts, or any of the other scenarios where you want to apply a digital signature to a Word DOC file.
Another important bonus in saving or converting Word DOC files to PDF is that you can sign documents in Preview with a Mac Trackpad or apply a digital signature to the PDF with Preview, allowing yourself or a recipient to view a Word document.
The freshly saved PDF from the DOC origin is now ready to use in any PDF-friendly environment, be it sending it with the original formatting preserved or posting it online, or whatever.
