Before we discuss how to unlock password protected PDF files, let's make sure that we understand what a PDF file means and discover why it is still so popular with individuals and businesses alike. So, here's a simple definition of a PDF file.


Part 1: What is a PDF?

Created by Adobe, PDF is an acronym for Portable Document Format, which is a file format that is commonly used to present and share documents in a manner that is both consistent and reliable. For the benefit of those who aren't familiar with PDF files, files that ends or have the extension .pdf are considered to be PDF files.

PDF File

Basically, PDF is a format that embodies all the elements of a printed file as an electronic document that users can look at, scroll through, print, or send to someone else, no matter the font, application, or operating system. In case you're still finding it hard to grasp, PDF files are pretty much like Word documents; however, unlike Word documents, PDF files are usually sent out as read-only files. If you don't have the necessary tool to overwrite it, then your PDF file will remain to be a read-only document.

As we know, PDF is used for formatting a document, such as license agreement, contract, etc. so it is very important to add a password or protection to it in order to keep it from further edition or unauthorized access.

PDF Protection

Aside from its portability, there are also other reasons why PDF are still so popular. PDF offers a number of interesting features that contribute to its popularity. One such feature is its ability to improve security settings. You could choose to restrict other users from copying or printing its content. In this way, it provides a lot of security for its users. Moreover, if you want to further secure your document, you can opt to password-protect your PDF file.
