Frequently asked questions
How strong is the protection?
Files are encrypted with AES-256. Use a long password that is hard to guess, since the minimum is only 4 characters.
What happens if I forget the password?
We cannot recover it, because the password never reaches our servers. Keep it somewhere safe and keep an unprotected copy if you need one.
Can I stop people printing or copying my PDF?
Yes. Tick Block copying text or Block printing. Most PDF readers honour these settings.
Is Protect PDF free?
Yes. It is a premium tool that free users can run by watching a short ad.
