There are two types of password protections in PDF which is,
- User Password – Password to open the PDF file
- Owner Password – Password to print, copy, modify the PDF file
If your PDF file is protected with User Password, this trick will not work for you. This tool will not be able to recover and remove the password from the PDF.
However if the PDF file is using Owner Password, this tool will decrypt and remove the password so you can print, copy, and make changes to the document.
