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?

Thank you.

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.

But since many pdf readers ignore not-copy/not-print-flags, another option would be to convert all the text to vector paths using e.g. inkscape, but this would bloat the pdf file heavily.

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

I have solved my problem using above pdftk command line. Thank you very much @jofel. –  Bakhtiyor Feb 23 '12 at 10:03
inkscape option was best one though, but my word document contained more than 100 pages and I had no time to import all of pages one-by-one into inkscape and to convert it to pdf. –  Bakhtiyor Feb 23 '12 at 10:05
@sunk818 Please read my full answer - the last sentence includes this case. –  jofel Sep 21 '14 at 10:02

Any PDF file can contain DRM (digital right management) feature: in other words a feature that disable copy-paste. You can find tons of software that does that, there are also few websites that propose to do it online without downloading a software (i.e online-pdf-nocopy.com)
