Frequently asked questions

What encryption does PDF Juggler use?

We apply AES-256 encryption with modern user and owner passwords that work in Acrobat and other viewers.

Can I block printing or copying?

Yes. Turn off printing or copying before protecting the file and the viewer will enforce those permissions.

Do you store my password?

No. Protection runs entirely in your browser, so neither the document nor the password leaves your device.

Can I remove a password later?

Yes. When you know the password, open the file in the Unlock PDF tool to remove it.

Does it work with long passphrases?

Yes. You can use up to 128 characters including spaces and emoji—longer passphrases improve security.
