Frequently asked questions

Is my document uploaded?

No. The PDF is rendered and signed entirely in your browser with PDF.js and pdf-lib. It never leaves your device — verify in DevTools → Network.

Is this a legally certified e-signature?

This adds a visible, handwritten-style signature image — great for everyday agreements and forms. It is not a certificate-based digital signature (like a qualified eIDAS/PKI signature), so for those use a certified provider.

Can I sign more than one page?

Yes. Draw once, then click each page where you want the signature placed.

Is it free?

Completely free, no account, no watermark — because everything runs on your device.
