Questions
Are my files uploaded anywhere?
No. Nibadai does the work inside your own browser, so your files never leave your device. You can even disconnect from the internet after the page loads and it keeps working.
How strong is the protection?
AES-256, the same strength banks use. A long password with numbers and symbols is very hard to crack.
What if I forget the password?
It can't be recovered - not by us or anyone. Keep it somewhere safe.
Is it really free?
Yes. There's no sign-up, no watermark and no daily limit.
