Good to know
- This adds an image of your signature — an electronic signature. It is not a certificate-based (cryptographic) digital signature, and it does not prove identity or detect later changes.
- Whether an electronic signature is acceptable depends on the document and the law where you are. If in doubt, ask the person requesting the signature.
- Signatures are not saved anywhere; you create a new one each visit.
Frequently asked questions
Is this signature legally binding?
Many countries accept simple electronic signatures for everyday documents, but some documents require qualified or certificate-based signatures. We can’t give legal advice — check with the recipient if unsure.
Do you store my signature?
No. Your signature is created and placed in your browser and disappears when you leave the page.
Can I sign on my phone?
Yes. Draw your signature with your finger in the Draw tab.
