I have a pdf that was created from scanning a book. unfortunately, the scanner quality wasn't the best and the text came out blurry. Somehow, adobe reader recognizes the blurry text, so I can highlight the blurry text, copy it, search within the text, etc. My question is if its possible to change all the text in the pdf into something clearer. note: i didn't create this pdf, and there's also pictures in to book so i would prefer to keep all the layout the same, just convert the "font" of the text. Is there any software that can do this?
