If so, try out Coolmuster PDF Encrypter, one of the most reliable and straightforward methods available for protecting PDF documents.

Drag-and-drop is supported, so you can bring all the PDF files you want to encrypt to the program’s interface at once by dragging and dropping them. No matter how big your PDF file is, encrypting it can be done in 3 easy steps.

You can control who can open your PDF with just a user password. Your PDF can only be opened by people who know the user password. Through the use of an owner password, you can restrict activities like copying, altering, and printing in high quality.

Offers 3 different levels of security:

This software lets users choose from 40-bit RC4, 128-bit RC4, and 128-bit AES encryption systems.

40-bit RC4: This is the lowest level of password protection that keeps users from printing, copying, or editing PDF files on their own.

40-bit RC4 isn’t as good as 128-bit RC4. It gives you more detailed options for putting limits on a PDF file.

Without a doubt, 128-bit AES is the best way to protect a password. It stands for Advanced Encryption Standard, which gives your file a stronger way to keep it safe.
