User Password vs. Owner Password

When adding a password to a PDF, you can set two types of passwords:

  • User Password: This password is required to open and view the PDF file.
  • Owner Password: This password grants control over permissions, such as preventing printing, editing, or copying content. Notice: it is possible to remove owner password from PDF without knowing the password!

Setting both passwords ensures maximum security and control over your document.
