Export as a transparent or white-background PNG for email sign-offs, Word or Google Docs, and letterheads. Everything runs locally: no upload, no account, no server. Built by FreeToolHub.
Draw with your mouse, trackpad, or finger on a touchscreen.

Background
Everything runs locally in your browser. Nothing you draw, type, or upload is ever sent to a server.
How it works
Choose Draw, Type, or Upload above. Draw sketches ink with your mouse or finger and auto-crops the empty canvas away on export. Type renders your name in a signature-style font you can resize and recolor. Upload turns a photo of your real signature into a clean cutout by fading light background pixels to transparent. Pick a transparent or white background, then download a PNG ready for email sign-offs, documents, or letterheads.

Frequently Asked Questions
Is this a legally binding electronic signature?
No. Signature Generator creates a personal signature image for casual use, such as email sign-offs, documents you prepare yourself, or letterheads. It is not a certified or legally binding e-signature. For contracts that require legal e-signature compliance, use a dedicated e-signature service instead.
Is my signature or photo uploaded anywhere?
No. Everything happens locally in your browser using JavaScript. Nothing you draw, type, or upload is ever sent to a server.
What's the difference between transparent and white background?
Transparent background removes the empty space around your signature so it blends into any document, background color, or email theme. White background fills that space with solid white instead, which some email clients or PDF viewers handle more reliably than transparency.
How does the "remove background" option work for uploaded photos?
It treats light or white pixels as background and fades them to transparent based on brightness, while keeping darker ink strokes intact. It works best with a signature written in dark ink on a plain white or light background.
Can I undo a mistake while drawing?
Yes. The Undo button removes your last stroke, and Clear wipes the canvas completely so you can start over.
What file format does it download as?
A PNG image, either with a transparent background or a solid white background depending on the toggle you choose before downloading.
