Frequently asked questions
How strong is the protection?
Toola uses 256-bit AES encryption, the strongest standard PDF encryption, supported by all modern PDF readers.
What if I forget the password?
It can’t be recovered — not by us or anyone else. Keep it in a password manager.
Is my password sent anywhere?
No. Encryption happens in your browser, so the password and the PDF stay on your device.
