Now you know at least four ways to merge PDF and Word documents. Our most recommended method is to use UPDF because you can merge a PDF and Word document into a single PDF, and then you can convert that PDF to many other file formats, including a Word document. You can then use UPDF to edit and annotate your merged file. You can also use PDF24 or ASPOSE to merge a PDF and a Word document into one file, but both of those websites have limitations.
