What is Coolmuster PDF Locker?

Coolmuster PDF Locker

Coolmuster PDF Locker is a great tool if you're looking to keep your PDF files safe. Locking a PDF with a password is a smart move, especially for sensitive documents. You want to ensure that only people with the right password can access them.

Why Use PDF Encryption?

If you need more options for securing your PDFs, using a third-party encryption tool can really help. This software lets you easily encrypt documents with passwords, choose your preferred encryption level, and set permissions that fit your needs.

Encrypt Multiple PDFs at Once

The best part about Coolmuster PDF Locker? It allows you to encrypt multiple PDFs all at once! This saves you time because you won’t have to go through each file one by one. However, just be cautious about using the same password for several documents!

User-Friendly Document Management

You should find it easy to add documents without any hassle. Just a heads up: we had some trouble with drag & drop features and ended up locating our files through the program itself. After that, setting up our encryption was simple thanks to the user-friendly options available.

Password Options That Fit Your Needs

You can set two different passwords: one for opening the PDF and another for changing permissions. Most folks will just want to restrict access from opening the document, but if it’s super important, blocking permissions is worth considering too.

Choose Your Encryption Level

The software gives you three levels of encryption: 128 bits AES or RC4 at either 128 or 40 bits. Each option works best with specific versions of Acrobat, so pick what suits your needs!

Toggle Permissions Easily

You can also tweak various permissions based on what you want others to do with your document. Decide whether they can copy or modify content, print it out, fill forms, and more—all customizable!

A Note for Free Users

Coolmuster PDF Locker is pretty handy overall! But keep in mind that free users can only secure their documents three times. Still, it's perfect if you're just looking to lock a few files here and there.
