How secure is the PDF encryption?

We use AES-256 encryption, the same standard used by banks and governments. It's virtually uncrackable with current technology.

Can I remove the password later?

Yes, you can open the protected PDF with your password in any PDF reader and save it without encryption.

Is my PDF stored on your servers?

No. Your PDF is processed and returned immediately. We never store your files.

What permissions can I restrict?

You can restrict copying text, editing the document, and printing. Content accessibility for screen readers remains enabled.
