How to Unlock A Password Protected PDF File for Free

Comment

Portable Document Format, also referred to PDF, is a format created by Adobe that is currently widely used around the world today. This format is not easy to edit directly, and it can ensure that no matter where the user opens the file, there will be no garbled characters. Therefore, businesses, schools, etc. are very fond of using this format to store their data.

File encryption is also very common nowadays. Many companies are accustomed to using PDF to store business data, and often encrypt files to ensure security. In this way, the files will not be edited, copied and stolen by unauthorized people. There are three types of encryption, 40, 128 and 256 bits. The safest of these is 256 bit, but it is also the hardest to crack (in case you forget the password). This article will recommend several methods below, for whether you know the password, and simply want to decrypt the original file, or forget the password, and want to ask for help to open the secured file.
