You've got a PDF file on your hands that you really need to print, copy, or otherwise edit but it's locked down like Fort Knox. You're out of luck, unless you use a service like FreeMyPDF.
A few years ago, I would have killed for a simple service like FreeMyPDF. Countless times people within my company would send me PDF files that had all sorts of unnecessary protections which frequently made it impossible for me to work with them the way they requested: "Hey can you print that off and bring it to the meeting?" "You locked it down with a password. I can't print it." "Oh really? Huh. I dunno what the password is."
FreeMyPDF helps you deal with situations like that. Upload the file to FreeMyPDF and passwords and restrictions are stripped from the file before it is returned to you. It should be noted however that the process only works for files you are able to view—files which you need a password to even view can't be unprotected by FreeMyPDF.FreeMyPDF
