Why You Should Password Protect PDF Files

With PDF Pro, it's easy to add a password to a PDF so you can secure personal, financial, business or other sensitive information contained in that file. If you plan on sending the file over email, storing it on a cloud service or putting it on a USB drive, add a password to a PDF file so you can control access to your data.

One note: when creating a password to protect PDF, we recommend following the advice of security experts by using a strong password. A strong password has at least 6 characters - though use of more characters results in an even stronger password - that combine lower and upper-case letters, numbers and symbols. Experts also recommend never reusing a password, so make sure the password you choose for your PDF file is unique.

PDF Protip: On using a password to protect PDF files

Once a password is set, other users will not be able to open the secured PDF unless they provide the correct password. You can update the password or unlock the file by providing the correct original password.
