Draw once, reuse everywhere
Sign in the box above with whatever you have: a mouse, a trackpad, a finger on a touchscreen or a stylus. The tool smooths each stroke as you draw, turning the jagged points a pointer produces into flowing curves, so even a mouse signature comes out looking like ink rather than pixel stairs. Pick black or blue, adjust the pen size to taste, and use Undo to remove the last stroke instead of starting over when one flourish goes astray.
The download is a PNG with a fully transparent background. That matters more than it sounds: a signature saved on a white rectangle leaves an ugly box when placed over a form's signature line, while a transparent one sits on the page as if it were written there. The white you see while drawing is only the drawing surface, not part of the file.
Getting it into a document
In Word or Google Docs, insert the PNG as a picture, set the text wrapping to "in front of text" and drag it onto the signature line. In most PDF editors, including the free viewers, look for an add-image or fill-and-sign option. For email signatures, resize the image down first so it does not dominate the message; a couple of hundred pixels wide is plenty on screen.
If the destination demands a specific file size or dimensions, the image resizer will scale the PNG without losing its transparency, and the image to Base64 tool can embed it directly in HTML.
An honest note on e-signature legality
In the UK, electronic signatures have been capable of being legally valid for most contracts for years, and that includes a drawn or pasted image of your signature. English law generally cares that you intended to sign, not what the mark looks like. The same broad position holds across the EU under eIDAS and in the US under the ESIGN Act. So for everyday paperwork, tenancy references, permission slips and routine business agreements, an image like this is normally fine when both sides accept it.
Be honest with yourself about the limits, though. A pasted image carries no evidence of who placed it or when, which is exactly what dedicated e-signing platforms add with their audit trails, and why they are preferred for high value contracts. Some documents also demand more formality: wills, many deeds and certain property documents need witnesses or specific execution rules, and an image alone will not do. If a document matters, check its requirements first.
Drawn on your device, never uploaded
Your signature is about as personal as data gets, so it is worth saying plainly: everything here happens in your browser. The strokes exist only on a canvas on your own device, the PNG is generated locally, and nothing is transmitted, logged or stored anywhere. Close the tab and the signature is gone, so draw as many attempts as you like and keep only the one you download.
This is guidance, not legal advice; for signature and execution requirements on specific documents, see the official guidance on gov.uk or take proper advice.
Frequently asked questions
Is my signature uploaded anywhere?
No. The drawing lives entirely on an invisible canvas in your browser and the PNG is assembled on your own device. Nothing is sent to a server, nothing is logged or stored, and closing the tab removes everything.
Why is the background transparent?
A transparent PNG drops cleanly onto any document, whatever the page colour, without a white box around the ink. Word, Google Docs, PDF editors and email signatures all support transparent PNGs, so the signature looks like it was written on the page.
How do I get a smoother line?
Draw slowly and at a comfortable size; the tool smooths your strokes as you go, but a slower hand always gives a cleaner curve. A stylus or a finger on a touchscreen usually beats a mouse. If a stroke goes wrong, Undo removes just that stroke rather than starting again.
How do I put the signature in a document?
Download the PNG, then insert it as a picture in Word or Google Docs, or use your PDF editor's add-image option. Resize it to sit on the signature line. Because the background is transparent, it will not cover any text or lines beneath it.
Is a drawn signature legally valid?
In the UK and many other countries, simple electronic signatures, including a drawn image, are generally capable of being legally valid for most everyday agreements. A pasted image proves little about who placed it, though, and some documents need witnessing or a formal signing platform, so check what your specific document requires.
