Works Well With Some Pdfs, Badly With Others

I originally used this to try to repair pdfs which Preview had damaged and bloated. It wasnt able to do that, and converted one to a plain gray blur. I have also used this to compress pdfs from the Internet Archive. It can sometimes do that. Depending on your requirements, this could be anything from 1 star to 5 stars.
