In addition to opening Word’s regular file formats, you can also open PDF documents for editing.
Click the File tab.
Click Open.
Select and open a PDF file.
A dialog box appears, explaining that opening a PDF in Word converts it to a Word document and opens it as a copy. You’ll be able to edit the text, but some formatting and graphics may look different.
Click OK.
A copy of the PDF is converted into an editable document, and it opens so that you can edit the text.
