Signature Maker

Create your handwritten signature in the browser

Sign your name in the box using a mouse, trackpad, or your finger on a touchscreen, then download it as a PNG with a fully transparent background. The transparent background means you can drop the image straight onto a contract, form, or email without an ugly white rectangle around it. Pick any pen color and adjust the stroke thickness to match the look you want, and use Undo to remove the last stroke if a line goes wrong.

Everything happens locally in your browser using an HTML canvas — your signature is never uploaded, stored, or sent anywhere. That makes it a private way to produce a reusable signature image for signing documents, PDFs, and online forms. For the smoothest result, draw slowly and in a single confident stroke; the tool smooths your path with quadratic curves so it looks natural rather than jagged.

FAQ

Is my signature uploaded to a server? No. The drawing and PNG export happen entirely in your browser. Nothing is uploaded, saved, or transmitted, so your signature stays private.

Is the downloaded image really transparent? Yes. Only your ink strokes are drawn — the rest of the PNG is fully transparent, so you can place it over any document or background.

Can I use this on my phone or tablet? Yes. The canvas supports touch and stylus input, so you can sign with your finger or a pen and download the same transparent PNG.

How do I undo a mistake? Tap Undo to remove your most recent stroke, or Clear to erase the whole signature and start over.
