Blurry/fuzzy pdf

    Hi folks,

    I got my hands on an ebook that's in a pdf format for a course I am doing at the minute. The problem is that the text and the images are all blurry/fuzzy making it a pain to read, I have to zoom right in to read the text. Also the text is not searchable if looking for a certain word - I guess the pages themselves are images. Is there any free software available to fix this? Apologies if I am asking the impossible without the original file.

    If the book was scanned as images with a low resolution, that would explain the poor quality. You can't ocr low res images to make searchable text.

    It's also possible that you don't have the embedded fonts installed on your PC.
    I haven't heard that happening in a while, but there is\was a trick to fixing it. I can't remember.
    I think it you had to open it in preview mode and save it as a new document...?

    I can't remember correctl.
    Try Foxit PDF, I think that installs a few fonts with it.

    I am afraid that might be the case. The text is barely legible at best, very frustrating

    It's not a font issue - OP can't do a text search so what he has is a series of scanned images. If you're missing fonts, Adobe will tell you as soon as you open the PDF and it will name the ones you're missing.
