Your PDF stays on your device
Most online PDF tools send your file to a server. This one runs in your browser instead, so there is nothing to delete later and nothing to leak.
- Works offline. Load the page, turn off the internet, and it still works.
- No account, no watermark. The result is yours, with nothing added.
Frequently asked questions
- Is this a legally binding signature?
- It places an image of your signature on the page, the same as signing a printout and scanning it. Many agreements accept that; some need a certificate-based digital signature, which PdfNib does not provide yet. When in doubt, ask the other party.
- Can I save my signature for next time?
- Yes. Tick the option in the signature dialog and it is kept in this browser only, ready to place again.
- Is my document uploaded?
- No. Opening, signing and exporting all happen in your browser.
