Frequently Asked Questions
Колко сигурно е използваното криптиране?▼
We use standard AES (Advanced Encryption Standard) encryption, the same cryptographic standard banks and governments rely on to protect sensitive data.
What happens if I forget the password?▼
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.
Мога ли да премахна паролата по-късно, ако вече не ми трябва?▼
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?▼
Не, криптирането се прилага изцяло във вашия браузър, така че паролата, която въвеждате, никога не напуска вашето устройство.
