Signature Generator

Draw your signature with mouse, finger or stylus — or type it in a cursive font — and export a transparent PNG or SVG at up to 3× scale.

The signature is drawn and exported in your browser. It is never uploaded or stored.

Draw with mouse, finger or stylus — strokes are smoothed automatically.

How It Works

Draw mode records each pen stroke as a list of pointer samples and renders it with the midpoint-quadratic technique: for every pair of raw samples the curve passes through their midpoint, using the samples themselves as control points. Type mode draws your text on the same canvas with a cursive font stack, auto-fitting the size to the frame. Every option — transparency, scale, padding — is applied at export time from the stored vector data, not by resampling a flattened image.

Why midpoint smoothing looks handwritten
Raw pointer samples form a jagged polyline, especially on trackpads. Replacing it with quadratic Bézier segments whose control points are the samples and endpoints are consecutive midpoints guarantees a smooth C1 curve that still hugs your actual path, and round line caps hide the seams. The same path math drives the PNG canvas and the SVG export, so draw-mode results match pixel for pixel in vector form.
SVG text depends on installed fonts
A type-mode SVG stores the text plus a font name — the machine that opens it resolves that name against locally installed fonts. Segoe Script ships with Windows, Snell Roundhand with macOS, and if neither is present the browser falls back to its generic cursive. This tool downloads no webfonts and does not convert text to outlines, so for typed signatures the PNG is the universally faithful export.
Scale and padding
The signature lives on a 560 × 220 working canvas; the export multiplies it by your 1×/2×/3× choice and adds the padding ring, so a 3× export with 40 px padding is 1800 × 780 px. Transparent background keeps the alpha channel in the PNG — the cleanest way to drop a signature onto letterheads and PDF pages without a white box around it.

Frequently Asked Questions

How do I put the signature into a Word document or PDF?

Download the PNG (transparent background keeps it clean over any page), then in Word use Insert → Pictures and drag it in, or simply copy the data URI and paste. Resize the image to your preferred signing height — at 3× export scale you have plenty of pixels to shrink without softening the strokes.

Is a signature made with this tool legally binding?

In most jurisdictions an electronic signature is valid whenever the signer intended to sign and the mark is associated with the record — a drawn or typed signature image pasted into a document usually qualifies. But validity also depends on context and proof of who applied it, which a plain image cannot provide. For high-stakes agreements, use a proper e-signature platform with audit trails, and treat this page as image creation, not legal advice.

My trackpad signature is shaky. Any tips?

Mouse and trackpad pointers are noisy — the smoothing helps but cannot invent steadiness. Draw slowly (fast strokes sample poorly), sign with a finger on a phone or tablet, or switch to Type mode and pick a cursive font: many people simply render their name in Segoe Script or Snell Roundhand and never draw it.

Will the SVG look the same on every computer?

Draw-mode SVGs will — the strokes are exported as pure vector paths, so they render identically everywhere. Type-mode SVGs store your text plus a font name, and the machine opening the file must have that font installed or it silently falls back to another script face. If you must send a typed signature with guaranteed fidelity, send the PNG instead (outline conversion is not implemented).

Is anything uploaded to a server?

No. The canvas, strokes and exports all live in your browser — your signature is never transmitted or stored anywhere. Once the page has loaded the tool works completely offline.
