I need to convert a Word document to PDF file so that user would not be able to copy any text or anything from it (pdf file).

How can I do that?

You can set the not-copy flag in the pdf file using for example pdftk (there exists GUIs for it). You need to set an owner password.

In all cases, the user could use OCR-software to extract the text, so there is no safe solution.
