One of the best features of PDF files is the password protection which can be usually set with any PDF editor. Some ebooks in PDF format adds more security by preventing users from doing copy, edit and print. The latest version of PDF uses 256 bits AES encryption, which is comparatively difficult to unlock. However, if the character length is less, there are some methods to recover passwords from older PDF versions. Here we have few utilities to unlock protected PDF documents to copy, edit and print them.

1.Unlock PDF files using online method :

Two online services Ensode and  Unlock-PDF allow users to upload PDF files to their server and  unlock them online. Converted PDF files can be edited as per user interest. First service let you to upload PDF file up to 5 MB in size, and will be opened in a new browser window after conversion. The second one has both free and premium PDF unlocking facilities, from which the later offers more advanced features for new and complex PDF encryptions.

2. Unlock PDF files and remove copy, edit and print restrictions using freeware PDF-crack (PDF1.6, Acrobat 7.0) .
