💡Pro tips

Use Blue Ink

If you are uploading a signature image, use 'Blue' ink to make it look original and distinct from the black text.

Transparent Backgrounds

Our tool automatically handles transparency so your signature sits perfectly on the line, not inside a white box.

⚖️Is this legally binding?

In most countries (including the US under the ESIGN Act and EU under eIDAS), electronic signatures are legally binding for most business transactions. However, for highly sensitive documents like Wills or Real Estate deeds, consult a local lawyer.
