Frequently Asked Questions
How secure is the encryption used?▼
We gebruiken standaard AES-codering (Advanced Encryption Standard), dezelfde cryptografische standaard waarop banken en overheden vertrouwen om gevoelige gegevens te beschermen.
What happens if I forget the password?▼
Zonder dit bestand wordt het bestand permanent onleesbaar. We bewaren geen kopie van uw wachtwoord of document, dus we kunnen het op geen enkele manier voor u herstellen. Bewaar het op een veilige plek.
Does password protection also stop people from printing or copying?▼
Setting an open password requires anyone to enter it before they can view the file at all, which covers printing and copying too, since they can't access the content without opening it first.
Can I remove the password later if I no longer need it?▼
Yes, use Unlock PDF and enter the password to strip it back off whenever the file no longer needs to be restricted.
Is my password sent anywhere while I'm setting it?▼
No, the encryption is applied entirely inside your browser, so the password you type never leaves your device.
