Why is the background transparent?

So the signature sits on top of the document without a white box around it. The image is also trimmed to the edges of the strokes, so it is easy to resize and position.

Which resolution should I choose?

Standard is enough for screens. For documents that will be printed, choose High or Very high: the strokes stay sharp when the signature is enlarged.

Can I use it to sign a PDF?

Yes. Download it and add it to your document, or draw it directly in Sign PDF , which places it on the page you choose.

Is a drawn signature legally valid?

An image of your handwritten signature is a simple electronic signature. It is accepted for many everyday documents, but contracts that require an advanced or qualified signature need a certificate-based signature.

Which ink color is best?

Black or dark blue look the most natural. Blue makes it easier to tell that a printed document was signed and not photocopied.

Drawn or typed

A drawn signature looks like your real one; it works best with a finger on a phone or a stylus on a tablet. A typed signature uses a handwriting font with your name: quicker, and consistent every time. Both are exported in the same transparent format.

Using your signature

Place it on contracts, delivery notes, invoices or forms. If the document is a PDF, Sign PDF adds it to the page without converting the file, and Edit PDF lets you also add the date or your name as text.
