Signature Generator
Draw a signature with your mouse, trackpad or finger, or type your name in a cursive style — then download it as a transparent PNG. Nothing you draw or type ever leaves this page.
Switching between Draw and Type clears the canvas below, so an export only ever contains one signature at a time.
Nothing is uploaded anywhere — the canvas, the drawing and the typed text all stay in your browser, and the PNG is built and saved on your own device when you click Download. This tool produces a drawn or typed image of a signature, not a cryptographic or identity-verified electronic signature. Whether an image like this is legally sufficient for a particular document depends on the document itself, what the parties involved have agreed, and the law that applies where you are — check the requirements for your document and jurisdiction before relying on it.
How it works
Draw mode tracks your pointer (mouse, trackpad, stylus or finger — the same events handle all of them) and strokes a line onto an HTML canvas as you move. Type mode measures your name in one of four cursive-leaning font stacks and shrinks it to fit, then draws it onto the same canvas as text. Either way, the canvas starts fully transparent rather than filled with a background colour, so "Download PNG" — which reads the canvas with toDataURL("image/png") and triggers a temporary, invisible download link — saves an image with a see-through background, ready to drop onto a document without a white box around it.
- Is the signature I create here legally binding?
- It can be, depending on the document and where you are — but this tool only produces an image, with no identity check, certificate or audit trail behind it. In the UK, an electronic signature is admissible in evidence under the Electronic Communications Act 2000, and under the UK's retained eIDAS Regulation an electronic signature can't be denied legal effect solely for being electronic; the Law Commission concluded in 2019 that one can validly execute a document, including a deed, "provided that (i) the person signing the document intends to authenticate the document and (ii) any formalities relating to execution of that document are satisfied." US federal law takes a similar line: under the ESIGN Act, a signature or contract "may not be denied legal effect, validity, or enforceability solely because it is in electronic form." Neither rule makes every electronic signature valid for every document — the formalities for your specific document, and the law of your jurisdiction, still decide. Check what your document requires, and consider a dedicated e-signing service if you need identity verification or an audit trail.
- Does anything get uploaded when I draw, type or download?
- No. The canvas, the drawing and the typed text stay in your browser's memory the whole time; "Download PNG" reads the canvas locally in JavaScript and saves the file straight to your device. This page makes no network request with your signature, ever.
- Why is the background see-through instead of white?
- The canvas is cleared rather than filled before you draw or type, and it's exported with
toDataURL("image/png"), which keeps transparency. That lets you paste the signature onto a document, PDF page or photo without a white box around it. If you need a solid background instead, paste it onto a white or coloured layer in whatever program you open the PNG in.
FAQ
Sources & legal basis
Method: Draw mode captures pointer input (mouse, touch and pen alike) with the browser's Pointer Events and strokes it onto an HTML <canvas>. Type mode renders your name onto the same canvas using the canvas font property, which accepts an ordinary CSS-style font-family fallback list — no external font file is loaded. "Download PNG" reads the canvas with canvas.toDataURL("image/png") and clicks a temporary, invisible <a download> link; the file is generated and saved locally only.
On legal validity: this is a plain-image signature, not a cryptographic or identity-verified one. The statements above are drawn from the primary sources below; none of them says an electronic signature is automatically valid for every document — formalities, the parties' agreement and local law still govern.
- Electronic Communications Act 2000, s.7 — electronic signatures (and their certification) are admissible in evidence as to authenticity and integrity
- UK eIDAS Regulation (retained EU Regulation 910/2014), Article 25 — Article 25 states: "An electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form or that it does not meet the requirements for qualified electronic signatures."
- Law Commission — Electronic execution of documents (2019) — an electronic signature is capable of executing a document, including a deed, provided the signer intends to authenticate it and any execution formalities are met
- US Code, 15 U.S.C. §7001(a) (ESIGN Act) — a signature, contract or record "may not be denied legal effect, validity, or enforceability solely because it is in electronic form"
