Frequently asked questions
What encryption is used?
AES-256, the same standard used by banks and governments. Without the password, the contents are unreadable.

It cannot be recovered — store it somewhere safe. If you still have the password, Unlock PDF removes it in seconds.
Is it safe to use Protect PDF online?
Yes. Files are transferred over HTTPS, processed on isolated servers, and automatically deleted within 2 hours. We never read, share, or train on your documents.
Is Protect PDF free?
Yes — every BreezyPDF tool is free to use with daily download credits (3 as a guest, 5 with a free account). BreezyPDF Pro removes all limits and ads.
