2. Create your signature: draw it with your mouse or finger, or type your name in a handwriting style.

Tips for a neat signature

• On a phone or tablet, drawing with your finger usually gives the most natural result.
• On a laptop, a trackpad is easier than a mouse. Draw slowly.
• Place the signature on or just above the signature line, and keep it a realistic size.
• Add the date next to it if the document asks for one.

Is an electronic signature legally valid?

In many countries, electronic signatures are accepted for a wide range of everyday documents such as rental forms, offer letters and invoices. However, the rules differ by country and by document type, and some documents (for example certain property, court or notarised papers) may require a wet-ink or certified digital signature. If you are unsure, ask the organisation that requested your signature. This article is general information, not legal advice.

Keep your document private

Signing happens in your browser, so your document is not uploaded to a server. That matters for contracts and personal paperwork.

After signing

• Use Flatten PDF if the document also contains filled form fields, so the answers cannot be changed.
• Use Compress PDF if the file is too large to email.
• Keep a copy of the signed version for your records.
