A PDF password removal is a tool that finds, removes, or bypasses the security on a PDF file which prevents a person from opening, changing, and printing it.

Some PDF password cracker tools recover the PDF user password, some recover the PDF owner password and others remove the PDF owner password allowing full access to the PDF file.

An individual PDF password removal tool might only be used for removing or cracking a password of a certain kind, for a certain security level, and encrypting a certain version of PDF. In most countries, PDF password crackers are used to break the security in only a PDF file that you have the permission to do so on.

The majority of PDF password removal tools cost money but there are also free ones available. The best of these include:



For those who want to recover PDF passwords, the PDFCrack is the best free recovery tool available. It recovers both the user and the owner’s password from encrypted PDFs. It uses a brute-force password recovery method, enabling you to know the actual owner or user password. The tool is completely portable and it downloads quickly.

However, the tool hasn’t been updated since 2008.
