SysTools PDF Unlocker review – Removes passwords from PDF files

PDF Files are one of the most widely employed file formats. It has gained popularity in recent times owing to its platform independence and the ease with which they can be exchanged over web. PDF files are made secure with the help of password variants applied on them. The user password restricts the PDF file to be opened by others whereas owner password restricts others from performing operations like editing, copying, printing, etc. on PDF files.
