How to sign

  • Open Sign PDF and add your document.
  • Draw your signature with a mouse or finger, or type your name in a signature font.
  • Click the page where the signature should sit, resize it, and download the signed PDF.

Drawn vs typed signatures

A drawn signature looks like your handwriting; a typed one is quick and tidy. Both are accepted for everyday paperwork — approvals, forms, delivery notes, offer letters.

What this is (and isn't)

This creates a visual signature — the electronic equivalent of signing with a pen. It is not a certificate-based digital signature with a cryptographic audit trail. For most day-to-day documents a visual signature is exactly what's asked for; for high-stakes contracts requiring verified e-signatures, use a dedicated e-signature service.

Private

Your document and your signature are processed in your browser and never uploaded — which matters, because your signature is sensitive.

Frequently asked questions

Is an online signature legally valid?

In many everyday contexts a visual electronic signature is accepted, but rules vary by country and document type. For contracts needing verified e-signatures, use a certificate-based platform.

Can I sign on my phone?

Yes — signing with a finger or stylus on a touch screen usually looks better than drawing with a mouse.
