What’s Protect PDF Tool

A protect, password, or safety tool of PDF deals in locking a PDF file with a solid and secure password.

By default, all PDFs are just a click away to get accessed by anyone. However, a PDF protection tool changes the ease of access by adding a password. This makes sure that only the people who are explicitly given access have the might to view it.

Not all programs capable of viewing & editing a PDF file have a PDF protection tool built-in. There are only a handful of softwares with a PDF password protector alongside other tools.

Some of the famous protect PDF tools are:

-Adobe Acrobat

Free Vs. Paid PDF Password Protection Tools

Free tools are mostly available online, and most of them require you to fill out a survey, download an app, and things like that. Also, there are free offline programs that you can install on your system. However, they are tied to specific systems and mostly come with a trial period.

On the other hand, we have paid tools. These are reliable to password-protect a PDF file. Moreover, some of them are available online, whereas the most popular ones are offline programs like Adobe Acrobat.

Which one is the winner? Well, the one that’s easily available online, trustable, and doesn’t spoof the users with ads, surveys, and other similar bags of tricks.

Why Add Password to PDF

Before we learn about how to add password to PDF, let’s see why to add it in the first place.

Primarily, a user adds a password to PDF to make sure it stays safe and secure from any unwanted access.

For instance, you are appointed to share some secret documents with your company’s board of directors. Indeed, you can mail the docs to their personal email addresses and call it a day. However, the not-so-smart action can cause severe consequences. What if they downloaded the files on their system, and it got stolen? What if their personal secretary peeked in them? So, a better thing to do would be to add passwords to the docs to maximize the security.

Imagine, your phone is the hub to all of your important PDF documents related to your education, home bills, finances, and more. Putting the docs on your smartphone has made it easily accessible for you to view them anywhere and anytime. But it has also raised a concern. What if your mobile got stolen or you forget it somewhere? All your privacy and critical information are just a few clicks away.

So, that’s that. Adding passwords to your PDF files is necessary. Just like you wouldn’t leave your home without locking it, the same goes for your critical PDF documents.
