SysTools PDF Lock

So, you want to keep your PDF documents safe? SysTools PDF Lock is the way to go! This tool makes sure that only you can access your files. As long as you remember your password, this handy software adds an extra layer of security and privacy to your important documents. It's a simple and effective way to keep them away from prying eyes.

Why Use SysTools PDF Lock?

Now, let's be real—locking multiple documents can feel like a bit of a hassle. But that's where SysTools PDF Lock comes in. Just add your files, set up the restrictions and password you want, and voilà! The software takes care of everything in just a few seconds.

Simplifying Your Document Security

As I mentioned before, it’s not super hard to secure several PDF files with passwords; it’s just kind of annoying. That’s why having this tool is great! It’s user-friendly and easy to figure out, so you won’t waste time trying to learn how to use it.

Free Version Limitations

You can lock as many files as you need, but keep in mind that the Free version only locks the first two files and adds a watermark on the output. Honestly, that watermark can be pretty annoying!

Password Protection Features

Besides securing your PDFs with a password, there are four different encryption methods available for you to choose from. You can also set restrictions on printing and modifying your documents.

Control Over Printing and Modifications

This means you can prevent someone from printing or limit them to lower quality prints. For modifications, you have options too! You can stop people from inserting or deleting pages or even filling out forms. And yes—if needed—you can completely block any changes!

The Bottom Line on SysTools PDF Lock

SysTools PDF Lock really is effective at locking multiple PDFs quickly. While it's decent for what it does, I wouldn’t recommend the Free version because of that pesky watermark in the Demo version.
