Frequently asked questions
Are my documents uploaded?
No. Signing runs entirely in your browser, so your files never leave your device.
Is it really private?
Yes. There is no server processing — the document, your signature image and the signed PDF all stay on your device.
Is there a watermark?
No. The signed PDF is clean with no watermark added.
Is this a legally binding e-signature?
It adds a visual signature to the page, like signing a printout. That is often enough for everyday documents, but it is not a certificate-based or qualified e-signature; check what your document requires.

The All Innovativ Sign Document tool lets you add a signature to a document without ever uploading your file — a free, 100% browser-based tool where everything stays on your device, with no account and no watermark.
Everything runs in your browser with pdf.js and pdf-lib; the document is never uploaded. Your signature image is created in the browser too and is not stored anywhere. The result is a visual signature, like signing a printout — not a certificate-based digital signature, qualified e-signature or tamper seal. It is free, needs no account and adds no watermark.
