🔒 How PDF Encryption Works

PDF encryption restricts access so that anyone opening the file must supply the correct password. Standard document permissions also allow you to prevent unauthorized printing or text extraction.

⚡ 100% Client-Side Privacy

Unlike other online tools that require uploading confidential bank statements or contracts to remote servers, all encryption and decryption runs entirely inside your browser's local memory.
