PDF is short for Portable Document Format which is great for business use and
sharing for its wide compatibility and safety. But nothing can be perfect, PDF file
also has its disadvantage. For example, many business PDF files are secured by
password, if you want to edit or split it, you are not allowed to do that because of
the PDF password security.
Edit Secured PDF
To edit a password secured PDF, we need to remove the password at first. We
call it "remove PDF password" not "crack PDF password" for a reason, removing
password protection from PDF files requires you know the correct password, it is
legit to do this, while cracking PDF files is sort of "hacking" job.
In general, PDF can be protected by 2 kinds of passwords: User Password
(required to open a PDF) and Owner Password (required to edit a PDF).
If a PDF is protected by both of the 2 kinds of passwords, you need to input the
correct User Password to make it password-free.
If a PDF is only protected by User Password, you also need to input the correct
User Password.
If a PDF is only protected by Owner Password, you can directly remove the
security without inputting anything. This kind of PDF is also called "Read only
PDF" by people.
Below is the newbie-proof guide about how to edit password protected pdf.
