The Microsoft Word file format, .docx, was designed by Microsoft as a default format for the Microsoft Office 2007 suite. However, despite the popularity and widespread adoption of Office 2007 applications, the .docx format provided numerous compatibility issues with previous Office versions from the very beginning.
PDF users, in particular, had a hard time finding a direct PDF to .docx converters. As a result, they had to resort to multi-step workarounds, converting PDF to .doc first and then re-saving the file from .doc to .docx.
Fortunately, with each succeeding version of Office since 2007, the format has gained better backwards compatibility. It is now a widely used default exporting and saving file format.
Moreover, you can now find PDF tools that serve as a direct PDF to docx converter. Here is how you can convert to docx from PDF by using PDF Converter Elite and Adobe Acrobat 11 Pro.
