Microsoft Word is the only software that’s guaranteed to render every .doc file precisely the same way as Microsoft Word. Other applications can come somewhat close, but the .doc format is not 100% precisely documented, and it’s so complicated that almost no one can render it perfectly. Even different versions of Microsoft Office render it slightly differently. In fact, even if you save .doc as .docx, it will render slightly differently. Then consider advanced features, such as Equation Editor, Word Text Art, or Excel sheets embedded directly inside the .doc. If someone wants to implement perfect rendering, t have to mimic not only the .doc file format, but everything that could potentially be embedded inside a .doc. Not every embeddable OLE object is openly specified. I’m not saying 3rd party implementations are bad, but most of them have slight differences in their rendering. Only you can tell whether you are OK with the result or not.
Note: For converting word files into PDF format, the output location must be the same path as the document you want to convert to PDF format. For example, when converting the above Excel file into PDF format, you must save the output location as c:\output\word.pdf. However, as soon as you click on “PDF to Word” on the Word to PDF” tab, the output location for that document will be different. Also, the saved PDF file must be in .PDF or .DOC format.
