Answer

Microsoft Word has the ability to convert a .pdf file to an editable Word document (.docx). 

Open MS Word. Click on the file tab and choose Open.  Browse your computer for the .pdf file you wish to edit then select and open it.

Upon opening, the following dialog box will appear:

Click on "OK" then the process of conversion will start.  After the document loads, immediately save it with the Save As function.  You can then edit the document and make changes.

If you have access to Adobe Pro, a .pdf document can be "Saved as Other..." where you can choose other software options:

  1. Open the .pdf document
  2. Go to "File," "Save as Other..." 
  3. A menu of file types appears - you can choose from Word, Excel, PowerPoint, Image and other options
  4. Give the new document a name, then find it and open it
