PDF Lock and Unlock
PDF Unlock Software is used for both locking and unlocking your PDF files. User can lock PDF files by applying User password and Owner password on PDF. You can also set all the PDF permissions like document print, edit, copy, modify, comments, annotations, form fill, accessibility, etc. With this program, you can enable or disable any security settings of PDF. If you are unable to print bulk PDF files, use this Unlock PDF Manager tool to print and modify your multiple PDF files on a single click.
Certain PDF files like bank statements, credit card bills, phone bills, etc are not only password protected but also locked to prevent any changes. You may have the password to open the PDF file but you cannot modify PDF or open it in an editor. If it is password protected, the program will ask you for the password to open the file. After entering the password, you just click 'Unlock PDF' button and the software will create an unlocked version (without security) of the same PDF file. This tool can work as Unlock PDF Files, Unlock PDF Protection, Unlock PDF Printing, Unlock PDF Password, Unlock PDF Permissions, Unlock PDF Security, Unlock PDF Copy Paste, Unlock PDF Commenting, etc.
