How to remove pdf pwd

Method 1 of 10: Finding What is Restricted

1. 
   1
   Open the PDF file. If you need a password to open the file, then you will need to download encryption-breaking software. This method is very CPU-intensive, and even the simplest passwords can take days to crack, leaving your computer unable to perform any other tasks during that time. For highly-encrypted passwords, there is little chance that it can ever be cracked.

   • Try copying. Restricted documents are often protected against copying. If you can’t highlight or copy any text, then the document has been restricted.
     
   • Try saving. Restricted documents cannot be saved as a text file. In order to convert it, you will need to unlock it.
