Encrypts your PDF with a password of your choice, and lets you restrict printing and copying. The file is encrypted entirely on your device before download — DCPIXEL never sees the file or the password.

अक्सर पूछे जाने वाले प्रश्न

What happens if I forget the password?

The PDF cannot be opened without it, and DCPIXEL has no way to recover or reset it since we never see the password or the file.

Can I restrict printing or copying separately from the password?

Yes. Even with the correct password, you can disable printing and/or copying permissions when protecting the file.

Is the encryption strong enough for sensitive documents?

This uses standard PDF encryption, suitable for everyday privacy needs like sharing personal or business documents. For highly sensitive/regulated data, consult your organization's security requirements.
