Is a visual signature legally valid?
In the UK, electronic signatures, including a typed name or an image of a signature, are generally capable of being legally binding for most everyday documents, such as consent forms, quotes and many contracts. Some documents have special rules: deeds, for example, usually need a witness, and certain government and property transactions have their own processes.
A visual signature shows intent to sign, but it doesn’t cryptographically prove who signed or that the document is unchanged. A certificate-based digital signature does both; PDF365 doesn’t create those. Our guide to electronic and digital signatures explains the difference, and how to sign a PDF without printing it covers the built-in options on Mac, iPhone, Windows and Android. This is general information, not legal advice; if in doubt, ask the person requesting your signature or a solicitor.
Security and privacy
Sign PDF runs entirely in your browser. Your file is processed in this tab’s memory and never uploaded to PDF365 or anyone else. When you close the tab or press “Start over”, the data is discarded.
Signatures are sensitive. Yours is drawn, rendered and embedded entirely on your device and is discarded when you leave the page. Consider flattening the signed PDF before sending it.

Questions about Sign PDF
Is this a digital signature?
No. It is a visual electronic signature: an image placed on the page. It doesn’t include a digital certificate or tamper-evident seal.
Can I sign on my phone?
Yes. Draw your signature with your finger, then drag it into place. Turning your phone sideways gives you a larger drawing area.
Can I save my signature for next time?
Not at the moment. We deliberately don’t store signatures. Keep a PNG of your signature on your device and upload it when you need it.
Can several people sign the same document?
Yes. Each person can add their signature in turn and pass the signed file on.
