Password protecting your PDF is a great way of securing all the vital information stored in the document, because it can be opened and viewed only by people who have the right credentials to access it.
Since you’re probably working with confidential information that is not meant to be seen by everyone, the best way to create secure, password protected PDF files is to use professional, desktop PDF software.
A secure way to protect your files is to use Able2Extract Professional to encrypt your confidential information and make your PDF files secure. You can utilize its advanced encryption to apply 256-bit password protection, set up advanced file permission options such as who can print and copy the document, and more.
On top of that, Able2Extract Professional allows you to add extra layers of security with the ability to permanently redact sensitive information and PDF watermarks.
Alternatively, you can password protect your PDF using one of the available online tools. However, we don’t advise doing so especially when dealing with confidential information as you would have to upload your file to an external server and input the password details as well.
