is there a paid app without monthly subscription that allows editing ,scanning doc and converting pdf to word and vice versa?
Finally, converting from PDF to Word is usually a silly thing to do. However, you could copy the text and paste it into a new word file to accomplish it.
PDFs are printouts. You aren't really meant to edit them, you should edit them in the app from which you are printing them (this is a very common misconception). Make sense?
