Is that to create a PDF?
I want to change it to a word document from a PDF.
Assuming you're converting it to word because you want to edit the document?
Or because you trying to upload it and they only allow word documents and not a PDF format?
Try cloudconvert.com
I use it for all my document conversations, they have so many options and usually works amazing.
But to tell you the truth never tried with a Hebrew document, try and see what happens.
