Frequently asked questions

Is signing PDFs free here?+

Yes — fully free, no watermark, no account required.

Can I sign from my phone?+

Yes. Scan the QR code with your phone, sign with your finger, and the signature flies back to your computer instantly.

Is my document uploaded somewhere?+

No. The PDF stays in your browser. The signature handoff between your phone and computer is end-to-end and the session is deleted right after.

Is a drawn signature legally valid?+

In most jurisdictions, electronic signatures are legally binding. For high-stakes contracts, check your local law or use a notarised e-signature service.

Can I pick the pen color?+

Yes — black, blue, navy, red, green, or any custom color to match a real-pen feel.
