Frequently Asked Questions
Is this a legal digital signature?
This tool creates an 'Electronic Signature', which is legally binding for most business and personal agreements (ESIGN Act, eIDAS). However, it is not a 'Digital Certificate' signature which is sometimes required for specific government or high-security financial transactions.
Can I choose different ink colors?
Yes, you can select Black (for official records), Blue (to distinguish original from copy), or Red (for corrections/marking).
Do you store my signature file?
Never. Your signature is created and kept only in your browser's temporary memory. Once you download the signed PDF and close the tab, the signature data is permanently deleted.
Can I sign on my mobile phone?
Absolutely. Our signing tool is touch-optimized, so you can sign with your finger or a stylus directly on your smartphone screen for a very natural look.
Is it safe for private contracts?
Yes. Processing is 100% local. Your contracts never leave your device, ensuring maximum privacy for sensitive legal data.
