PDF Page Lock enables users to lock or hide selected pages of a PDF document with a password encryption. With PDF Page Lock, users could hide or lock selected pages of a PDF file while leaving all other pages available.
One great advantage of PDF Page Lock is that the document in whole remains accessible on any computer, while the locked pages become protected. Hence, encrypting the entire PDF file is not necessary, and no third-party software is required to see such a protected PDF document on other computers.
