Is my name, my signature, or my uploaded image sent to a server?

No. Signature Tools is 100% client-side. Typing renders through the Canvas API in your browser, drawing captures pointer events onto a canvas in memory, and an uploaded image is decoded locally — your name, your drawn strokes, and your image never leave your device. There is no backend and no /api route. The site's Content-Security-Policy (connect-src 'self') even restricts which hosts the page may contact, so the privacy guarantee is enforced by the browser itself.

How do I type a cursive signature?

Open the Type mode, enter your name, and pick a cursive style (Dancing Script, Caveat, Great Vibes, or Sacramento). The fonts are bundled same-origin (no Google Fonts fetch), so they load instantly and work offline. Adjust the size and ink color, then download a transparent PNG, a vector SVG, or a PDF.

Can I draw my own signature with my mouse or finger?

Yes. Draw mode captures pointer and touch events on a canvas and smooths the stroke into a clean curve. Set the pen width and ink color, draw, then clear and redraw as many times as you like. Export the result as a transparent PNG, a vector SVG (real elements), or a PDF.

What does Upload mode do?

Upload mode lets you load a photo or scan of your existing signature, then cleans it with a luminance threshold so the dark ink stays and the background becomes transparent. Adjust the threshold slider until only your signature remains, then export PNG, SVG, or PDF. The image is processed entirely on your device.

What is the difference between PNG, SVG, and PDF export?

PNG is a raster image with a transparent background — drop it straight into a document, email, or form. SVG is a vector image (for Type, the font is embedded so it renders anywhere; for Draw, the stroke is a real ) — it scales without any pixel limit. PDF places your signature on a clean page via pdf-lib, ready to print or attach. All three are generated locally through same-origin blob: URLs.

Is this a legal e-signature?

No — and we are clear about that on the About page. Signature Tools creates a signature IMAGE you can place onto a document. It does not create cryptographic or AcroForm signature fields, and it does not record an audit trail. For legally binding e-signatures with identity verification and an audit log, use a dedicated e-signature service. Signature Tools is for producing the image itself.

Create a signature image from a photo

Upload an image of your signature and clean it into a transparent signature image. The luminance threshold keeps the ink and drops the background — all on your device.

Upload a signature image

Threshold (180)lighter → transparent

Ink color

Upload a photo or scan of your signature on a light background. Adjust the threshold so only the ink remains — the background becomes transparent.

Works best on a light, even background. Processing is local — the image never leaves your device. SVG export embeds the cleaned image as a self-contained vector file.

Upload an image first

How to trace a signature from an image

Upload a photo or scan of your signature (on a light background).
Adjust the threshold slider so the dark ink stays and the background turns transparent.
Download the cleaned signature as a transparent PNG, a vector SVG, or a PDF.
