Use any random PDF to WORD converter from internet. If PDF file is Searchable you can simply open that pdf and copy the entire text and Paste in new word doc file If PDF is non searchable, its impossible to fetch out text from it, you can get jpeg image our of that file to paste into word or anywhere else, but pretty useless option. note. most of the marathi book PDFs are created as image-pdf i.e. non-searchable PDFs by scanning those hard copies, you can not get text out of it unless some advance image reading algorithm is available
So basically, if a PDF is scalable, it can yield text from it, but if not, it's pretty useless.
