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