Windows only: The latest editions of Microsoft Office might have made some welcome interface and functionality improvements, but the newer .docx file formats can leave your co-workers (and your other computers) struggling to open its files. Free conversion utility Docx2Rtf can take whatever Office 2007 (or OpenOffice) files, and then display them for copying or save them as Rich Text Format, the standard nearly every text editor can understand, as well as PDF if you want. The conversion isn’t always perfect, due to RTF’s limited special characters and images, but Docx2Rtf can make it easy to send out documents to recipients across the computer spectrum. Docx2Rtf is a free download for Windows systems only. To convert older Word documents, try using Google Docs as a go-between.
