  • Click button Open to add PDF file to software interface. If the password protected PDF file is mixed together with the normal PDF file, please do not worry. Simply add all of them to software interface, the normal PDF will give error message. And the password protected PDF will be removed the password directly.
  • During the removing password, you will be removed to specify the output folder and name one by one. Once you specified the output folder, the removing process will end.
  • But when you remove the open password protected PDF file, there will be pop up message reminding to input the password. But you do not need to input both, normally if you  know one of the user password or owner password and input it in the dialogue box then the removing process will succeed.
