Why You Should Password Protect PDF Files

With DocFly, 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.
