Frequently Asked Questions
Quina seguretat s'utilitza el xifratge?▼
We use standard AES (Advanced Encryption Standard) encryption, the same cryptographic standard banks and governments rely on to protect sensitive data.
Què passa si oblido la contrasenya?▼
The file becomes permanently unreadable without it. We don't keep a copy of your password or your document, so there's no way for us to recover it for you — store it somewhere safe.
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?▼
Sí, utilitzeu Desbloqueja PDF i introduïu la contrasenya per retirar-la sempre que el fitxer ja no s'hagi de restringir.
Is my password sent anywhere while I'm setting it?▼
No, el xifratge s'aplica completament dins del vostre navegador, de manera que la contrasenya que escriviu mai no surt del vostre dispositiu.
