📘 How to Use PDF Encrypt / Decrypt Tool
Choose either Encrypt PDF to add a password or Decrypt PDF to remove a password. Upload your PDF, enter the password (for decryption, you need the correct password), and click the button. The processed PDF will be downloaded automatically. All operations are performed locally in your browser – your files never leave your device.
