Frequently asked questions

Is this a legally binding signature?

A drawn signature on a PDF carries the same legal weight as a handwritten signature in most jurisdictions — but isn't the same as a cryptographically signed PDF. For high-value contracts, use a dedicated e-signature service.

Can I add multiple signatures?

Not yet — one signature per run. Re-run the tool on the output to add more.

Is my signature uploaded anywhere?

No. The signature is drawn on a canvas in your browser and embedded into the PDF locally. Nothing leaves your device.
