part 1. What is PDF Password Remover?

GeekPDF is a tool for removing passwords from locked or protected PDF files. Password Decoding is necessary when you get a protected PDF file and don't know or remember the password. Such PDF files have an "owner" or "user" password that prevents users from viewing, copying, editing, selecting text, or printing the file, and prevents access by unauthorized users. Thus, PDF Password Remover software can unlock and decrypt owner or user password from any protected PDF file or document. Now comes the question, what are the owner and user passwords?

  • Owner Password:   PDF Owner Password is another name for PDF Master Password or PDF Authority Password. It protects PDF documents for editing, printing, extracting content, etc. Once an owner password is set, Acrobat needs it every time it wants to make any changes in the file.
  • User password:  Also known as the PDF file opening password, set by the PDF user to prevent others from viewing it. This is one way to protect confidential PDF documents from being seen by others. To view the file, you must enter the correct password that Acrobat prompts you for when you try to open it.
