Is a signature added to a PDF online legally binding?

In the EU (eIDAS) and the US (ESIGN Act and UETA), a simple electronic signature such as a typed name is valid for most contracts as long as it shows the intent to sign. Some documents, such as certain property transfers or court filings, need a qualified or certificate-based signature.

Is this a digital signature with a certificate?

No. Sign PDF adds a visible signature to the page. A certificate-based digital signature also seals the file against changes and can be checked with a signature validator. Flatten the signed PDF if you want the signature to become fixed page content.

Is a drawn or typed signature legally binding?

In many places a simple electronic signature like this is accepted for everyday agreements, for example under the US ESIGN Act and the EU eIDAS regulation. It is an image of your signature, not a certificate-based digital signature, so it does not prove who signed or that the file was not changed afterwards. For contracts that require that, use a qualified e-signature service.

Can I sign on a phone or tablet?

Yes. The drawing area works with touch, so you can sign with a finger or stylus. You can also type your name or upload a photo of your signature instead.

Is my signature stored or uploaded?

No. Your signature is created in your browser and only written into the PDF you download. noll does not keep a copy and nothing is sent to a server.

How do I add the date next to my signature?

Open Add Text to PDF in the same editor, click next to the signature and type the date. Both are written into the PDF when you download it.
