How it works

A compact workflow from input to download.

1

Draw your signature

Sign with your mouse, trackpad or finger. A touchscreen gives by far the most natural result.

2

Adjust it

Change the pen thickness and colour, and clear and redraw until it looks right.

3

Download the PNG

Save it with a transparent background so it sits cleanly on any document.

Frequently asked questions

Is an image of my signature legally binding?
It depends on the jurisdiction and the document. Many countries recognise electronic signatures for most everyday agreements — the US ESIGN Act and the EU's eIDAS regulation both give them legal standing. But a pasted image is the weakest form of electronic signature, because it carries no evidence of who applied it or when. For anything of real consequence, use a proper e-signature service that records an audit trail.
Why does the transparent background matter?
Because a signature on a white rectangle will visibly sit on top of whatever it is placed over, covering the signature line and any text near it. A transparent PNG lets only the ink show, so it looks like it was signed on the page rather than pasted onto it.
Is my signature uploaded anywhere?
No. It is drawn on a canvas in your browser and exported directly to a file on your device. It never touches a server — which matters, because a signature image is a sensitive thing to hand to a stranger.
How do I get a better-looking signature?
Use a touchscreen and your finger, or a stylus, rather than a mouse — a mouse is a genuinely poor instrument for handwriting and the result usually looks like it. Sign larger than you think you need to, since detail scales down cleanly but cannot be added back, and expect to take several attempts.

What a signature is actually for

A signature does two jobs that are worth separating. The first is evidentiary: it is a mark that is difficult for someone else to reproduce convincingly, so it links a specific person to a document. The second, and legally the more important one, is ceremonial — the deliberate act of signing marks the moment you intended to be bound. Courts have long cared more about demonstrable intent than about the mark itself, which is why an X made by someone who could not write has been binding for centuries, and why 'I accept' clicked on a screen can be too. Understanding that helps explain why a pasted image of a signature is weak: it proves nothing about intent, because anyone holding the image file could have applied it.

Handle the image file carefully

Once your signature exists as a PNG, it is a small file that anyone who obtains it can paste onto any document they like. That is worth taking seriously. Do not email it around casually, do not store it in a shared folder, and think twice before uploading it to a website that offers to 'make a signature' for you on a server. If you need to sign documents regularly, a dedicated e-signature service is genuinely safer than a reusable image, precisely because it binds each signature to a specific document, a specific person and a specific moment, and produces an audit trail. An image file has none of that — it is a rubber stamp, and rubber stamps get stolen.
