A PDF file that has been secured with the help of a strong and robust password has supposedly enough protection in order to avoid duplication or distribution by unauthorised users (assuming of course that the recipient who has been given the password in order to open it does not share this with others). The creator of a PDF file can use password protection to limit user access to the file (document contents are encrypted), prevent printing, copying of text from the file, and editing the content in the document.

However, the question arises as to what needs to be done if the original password created by the user has been forgotten? There are a number of PDF password remover tools that are easily available on the Internet in order to access lost passwords. Here, it is important to mention that PDF password protection remover tools were initially invented to be used only under appropriate circumstances – that is only if the original creator of the PDF file has lost the password and if the user has the legal right to view and modify the PDF but does not have the password.
