Frequently asked questions

Is a browser-drawn signature legally valid?

In most countries (US ESIGN Act, EU eIDAS, Mexico Código de Comercio), simple electronic signatures are valid for common agreements when both parties accept. For documents requiring qualified signatures (notarial deeds, real estate), you need a certificate-based signature (Adobe Sign, DocuSign, government eIDs).

Does Toolram add a watermark to the signed PDF?

No. The output PDF contains only your original document + your signature overlay. No 'Made with Toolram' watermark.
