I recently bought membership to a online course. It has hundreds of PDFs, and each PDF has a password, a DIFFERENT password at that. It is too late to get a refund, and I plan to use that knowledge from those PDFs anyway.
Anyway, I don't have the patience to remember 150 passwords - is there any free way to remove the passwords from those PDFs? I am on Mac OS X Lion. I don't feel like spending more money on this, so am looking for some free tool.
