The most recent versions of all Microsoft Office programs have facilities to export documents to PDF format.

Wherever possible, please do this in preference to uploading documents in proprietary Microsoft formats (e.g. docx, pptx, xlsx, and so on). Not everyone has these programs installed on their computers.

Of course, if there’s a strong reason why people will need to open the document in Office (e.g. a form to be filled in and emailled back, or a Powerpoint file for display at a meeting), then that’s different. You might consider uploading both the original file and a PDF version to keep everyone happy.
