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.
Is this a legally valid signature?
It's a simple electronic signature, accepted for most everyday documents. Some legal or government forms require a certified digital signature instead.
Does Nibadai keep my signature?
Only if you tick 'Remember on this device' - then it's stored in your own browser, never on a server.
Can I add initials on every page?
Yes: add your initials, select them, then press 'Put on every page'.
What if my PDF has a password?
Unlock it first with Unlock PDF (you'll need the password), then come back. It only takes a moment.
Is it really free?
Yes. There's no sign-up, no watermark and no daily limit.
