What you get

Two files, both with a transparent background and both cropped tight to the ink. The PNG comes out at three times the drawing size, which is enough for print. The SVG has no fixed size at all — it is the stroke geometry, so it is sharp on a business card and on a poster.

Why the stroke thins as you move

A real pen puts down less ink when it moves quickly. The pad measures the speed between samples and narrows the line to match, which is the difference between something that looks handwritten and something that looks traced with a mouse. On a high-refresh screen it reads every intermediate sample the browser captured, so a fast flourish keeps its shape instead of turning into a polygon.

A drawn signature is not an electronic signature

This produces a picture of your signature. That is what most documents ask for and what most people mean by "sign here" — but it is not a cryptographic signature, and it carries no proof of who drew it or when.

For anything where that proof matters — a contract of value, a legal filing, anything a court might have to look at — you want a qualified electronic signature from a certificate provider, not an image. Which one applies depends on the document and the country, and this page is not the place to guess on your behalf.

Nothing is stored

Your signature exists in this tab and nowhere else. It is not uploaded, not saved to any account, and gone when you close the page unless you download it. A signature is one of the few images genuinely worth being careful with, and "we process it on our servers" is a sentence that should give anyone pause.

Questions people actually ask

Is the background really transparent?

Yes, and it is cropped to the ink as well. Drop the PNG onto a coloured letterhead or a scanned page and there is no white rectangle around it — which is the giveaway that turns a signature into an obvious paste job.

PNG or SVG?

PNG for pasting into a document, an email or a form: it works everywhere. SVG when the signature will be printed, placed on a letterhead, or used at a size you have not decided yet — it is vector, so it stays sharp however large it goes.

Can I sign with a finger on a phone?

Yes. The pad uses pointer events, so a finger, a stylus and a mouse all work the same way. Turning the phone sideways gives you a wider stroke to work with, which most people find easier.

Why does the line change thickness?

It thins as the stroke speeds up, the way a pen does. A constant-width line reads as a drawing; a varying one reads as handwriting. The nib slider sets the baseline width.

Is my signature uploaded?

No. It is drawn on a canvas in this tab and exported here. Nothing is sent anywhere, and nothing is stored unless you save it yourself — which matters rather a lot for a signature.
