Portable Document Format (PDF) is a file format developed in the 1990s by Abode. This file format is more secure than other formats including .docx of Microsoft Office Word and that is the reason that when we share documents, it is recommended to be shared in a PDF format. That is not it; PDF files can also be password protected and are only accessible to those who have the password! Now, here's the catch! What if you have forgotten the password of a PDF document? Would that mean you will not be able to access the PDF anymore? Well, we have a solution for you that can help you edit and open Password Protected PDF files without the password.
