How to open locked PDF on smartphones and PC

Have you ever found a file with a locked PDF format and its contents cannot be copied or printed? Though the contents of the file are important and are needed quickly.

Now you no longer need to retype the entire contents of the document because there are many free services that can open locked PDF files without using software or applications.

But, keep in mind that there are two types of keys that are commonly used in PDF files, namely the owner password and open password. The owner password is usually used to protect your PDF files from ignorant hands who want to change their contents. So other people can read your files but can’t do any editing.

While the open password is the key that is placed so that others can not access the file. If you forget the password to open this file, you also cannot access it. Unfortunately, this locking method cannot be opened using any service or application.

Therefore, the tips below only apply to PDF files that are locked by the owner password method. Here’s how to open locked PDFs on smartphones and PCs.
