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.
Can I use Hindi or other languages?
Yes - any language your device can show works in a text watermark.
Can people remove the watermark?
It's part of the page content, so casual readers can't. Determined users with editing software sometimes can - for real protection, also use Protect PDF.
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.
