If you ever decide your file no longer requires a password lock, you can always jump back to Smallpdf and use our Unlock PDF tool. The previously mentioned password managers can also help with sharing passwords securely.įor extra security we won’t keep your passwords on file, so make sure you don’t forget it! Without the correct password you won’t be able to open, edit, or remove the protection from your own PDF. Only you and the people you give the password to will be able to access or edit your PDF file. Which is why we use 128-bit AES encryption to ensure your PDFs have a strong password protection. You don’t want your information getting into the wrong hands, and neither do we. Plus you can store all of your passwords in their vaults, protected by one master password. With such online software, you can choose your password characteristics and they will automatically generate one for you. But how is anyone supposed to follow all these password guidelines AND make it memorable? If you need help you can use a password manager, such as Lastpass or Dashlane. It’s also a good idea to make sure it’s something memorable, so that you don’t have to write it down anywhere. You should also avoid anything too obvious, such as the name of the file, your name, or any of the most common passwords (like “password”)!

A strong password is considered to be at least 8 characters long, and includes numbers, special characters and capital letters.

So, you’ve got a PDF file you want to protect, and now you just need to come up with the perfect password to ensure absolutely no one is getting to it unauthorised. Just drop your file into this tool and convert your Word, Excel, JPG or PPT file into a PDF and follow the same instructions above. If you’re wondering how to password protect a file that isn’t in PDF format, we’ve got you covered for that too.
