Microsoft Word's native file formats are denoted either by a .doc or .docx file extension.

The old DOC extension has been used in many different versions of Word before Word 2007.

The newer DOCX extension signifies the Office Open XML international standard for Office documents and is used by Word 2007, 2010 and 2013 for Windows, Word 2008 and 2011 for the Macintosh, as well as by a growing number of applications from other vendors, including OpenOffice.org Writer, an open source word processing program.

You can convert Word to PDF online, by our PDFConvert desktop software or command line program.
