Draw a signature online — transparent PNG download
Draw your signature with a mouse, finger or stylus and download it as a transparent PNG, trimmed to the ink and ready to drop into any document.
Runs entirely in your browser — nothing is uploaded.
All processing happens in your browser. Your file is never uploaded.
The signature is drawn and exported entirely on your device as a transparent PNG, trimmed to the ink — ready to drop into documents, email footers or the sign-PDF tool here. A drawn signature image is fine for everyday paperwork; it is not a certificate-based digital signature of the kind some jurisdictions require for specific contracts.
How to use
- Draw on the pad. The guide line helps keep the baseline straight. Undo removes the last stroke.
- Pick pen colour and width. Black and blue are the conventional choices.
- Download the PNG. Transparent background, cropped to the signature itself.
Questions
Where does my signature go?
Nowhere. It is drawn, trimmed and exported entirely inside your browser — a signature is exactly the kind of thing that should not be uploaded to a stranger’s server, which is the point of doing it this way.
Why a transparent background?
So the signature sits on any document without a white box around it. Word, Google Docs, email signatures and PDF tools all respect PNG transparency. The image is also trimmed to the ink, so it aligns predictably.
Is a drawn signature legally valid?
For everyday purposes — internal approvals, invoices, letters — an image of your signature is routinely accepted. Some contexts require certificate-based digital signatures with identity verification (a different technology), and some documents require wet ink by law. This tool makes the image; whether an image suffices depends on the document.
Mouse signatures look shaky — any advice?
Draw large — the pad rewards big strokes, and the export scales down, which smooths wobble. A phone or tablet with a finger or stylus gives a much more natural line: open this page there, draw, and the PNG downloads the same way.
