How to sign a PDF

Draw your signature with your mouse, trackpad or finger, pick the page and position, and place it. Because everything runs locally in your browser, your contract or agreement is never uploaded anywhere — a real advantage when signing sensitive documents.

Drawing or typing a signature

Draw with a mouse, trackpad or finger, or type your name and pick a handwriting style. Place it where it belongs, resize it, and save. On a phone or tablet, drawing with a finger gives a far more natural result than a mouse does.

What kind of signature this is

This produces an image of your signature placed on the document — the same legal category as printing, signing and scanning, and accepted for the overwhelming majority of everyday agreements. What it is not is a cryptographically certified digital signature with an audit trail and identity verification. If a contract specifically requires a qualified electronic signature, or you need a record of who signed and when, use a dedicated e-signature service. For a lease, a consent form, an invoice or an internal approval, this is the right tool.

Stopping the signature being reused

Once a document is signed, anyone who receives it has an image of your signature. If that concerns you, flatten the document and consider password protecting it before sending. Never post a signed document publicly.

Frequently asked questions

Is signing a PDF online safe here?

Yes — your document and signature are processed on your own device and never uploaded to a server.

Can I sign on my phone?

Yes, the signature pad works with your finger on touch screens.

Is this a legally binding signature?

It places a drawn signature image on the document, which many everyday agreements accept. For certified digital signatures with identity verification, a dedicated e-signing service is required.

Is an electronic signature made this way legally valid?

For most everyday agreements, yes — it is equivalent to printing, signing and scanning. It is not a certified digital signature with an audit trail, so check first if a contract specifically requires one.

Can I sign a PDF on my phone?

Yes, and drawing with a finger produces a much better signature than a mouse does.

Is my signature uploaded anywhere?

No. It is drawn and placed entirely in your browser, so the image of your signature never leaves your device.
