User Password is also named as Open Password. It is used to protect PDF files from opening. If a PDF file is protected with a User Password, people need to enter the right password to open it.
Owner Password is used to protect PDF files from copying, editing and printing. If a PDF file is protected with an Owner Password, people can read it, but cannot change it.

This PDF Password Remover tool will decrypt and remove owner passwords from any PDF document.

The Password Remover tool will NOT work with PDF files that have a "user password" set.
