Password Protect & Encrypt PDF Files With Ease

We all use PDF files at some point during our computational tasks, and will Inevitably continue to do so. Some files may hold sensitive data, such as those generated at your work containing transaction or Identification details, hence anyone with physical access can view the document without restrictions. As a result, In this tutorial, I will show you how to password protect PDF files with Incredible ease.

Whilst a lot of users simply utilize PDFs for educational purposes by (for example) downloading their favorite eBook on technology, there are also those who store some sort of personal Information. If someone with malicious Intent got a hold of It, the ramifications can be quite serious.

Fortunately, PDFs allow you to protect It with a password, but finding free software that actually works, Is not so easy. I've spent hours on end testing various freeware tools and applications that claim to password protect PDF files, however the majority either corrupted It or failed to function In It's entirety.

Rest assured, the one (free) tool that serves It's objective without error, Is named Instant PDF Password Protector, which can be downloaded from the developer's website. Although It's very easy to use, I've Identified that one particular encryption key algorithm that the tool entails, must be used to work on every file. So without further delay, let's get this tutorial started.

Step One:

Once you've downloaded the tool, It must be Installed on your computer. The process Is self-explanatory, so I won't go Into detail about that. This Is what you'll see on completion.

Step Two:

Execute the tool via the desktop or Start Menu, and select the Input PDF file option as shown below.

Step Three:

Next, navigate to the directory of the PDF file that you wish to protect. In my case, It's named Windows 10 Tips.pdf. When done, hit Open.

Step Four:

In the Password Input field, do just that by entering your password, and then click on the button as arrowed In red. You can leave the Output PDF File at It's default state, or select one of your own.

Step Five:

The encryption key algorithm that I found to work without Issues, Is 40-bit RC4. Select It via the drop-down menu, and then hit Save.

Step Six:

To encrypt and apply the password, simply hit the Protect PDF File button.

Step Seven:

If all goes well (there's no reason why It shouldn't!), the message as per the Image below will be returned. Click OK to finalize the process.

Step Eight:

Upon navigating to the output directory, my Windows 10 Tips file has been saved & password protected. This Is confirmed by protected.pdf.

Step Nine:

Now let's make sure that both the file and password, are fully functional. I've opened my file In Microsoft Edge, entered my password and hit OK.

Step Ten:

As you can see, my PDF file has successfully opened, hence all has gone according to plan.

Last Step:

And now for the final test. I need to make sure that my file does not open with just any random password, so I've entered something completely Irrelevant. As expected, an error message was returned.

Final Thoughts:

I'm a firm believer that any tool that's free of charge and developed to serve It's objective, should function In a similar fashion to It's paid alternative. The Issue however, Is locating one that works without loss of functionality to the tool Itself, and the file It's password protecting. Instant PDF Password Protector, does the job as Intended. It will not let you down.
