The PNG has a transparent background, so it drops straight onto a contract or invoice. Your signature is drawn and saved on your device — it is never uploaded.
Free Signature Generator
Sign with your mouse, trackpad or finger, then download a trimmed PNG with a transparent background that drops straight onto a contract or invoice. Nothing is uploaded.
What is the signature generator?
A signature generator lets you draw your handwritten signature on screen and save it as an image you can place on digital documents. Instead of printing a contract, signing it, scanning it and emailing it back, you draw once and reuse the file. The download here is a PNG with a transparent background, trimmed to the ink, so it sits cleanly over a contract or invoice without a white box around it. Because your signature is a piece of personal identifying information, it matters that this runs entirely in your browser — the image is created on your device and never uploaded to or stored on any server.
How our free signature generator works
Draw your signature
Sign in the box with your mouse, trackpad or finger. A touchscreen or stylus gives the most natural result.
Adjust the pen
Set the ink colour and thickness — a slightly thicker pen usually looks better than a hairline.
Download the PNG
The image is trimmed to your signature with a transparent background, ready to drop into a document.

Why use the signature generator?
Transparent background
Drops onto any document without an ugly white rectangle behind it.
Automatically trimmed
The PNG is cropped to the ink, so it scales and positions cleanly.
Stays on your device
Your signature is personal data — it's never uploaded or stored here.
Tips for getting the best results
Use a touchscreen or stylus if you can
A finger or stylus on a phone or tablet produces a far more natural signature than a mouse.
Sign larger than you think
Fill the box. A large signature scaled down looks smooth; a tiny one scaled up looks jagged.
Try it a few times
Clear and redraw until it looks right — most people's third or fourth attempt is the best.
Save the file somewhere safe
Treat the PNG like a physical signature. Keep it out of shared folders and don't send it to anyone who doesn't need it.
Frequently asked questions
Is a drawn signature legally binding?
In many countries an electronic signature is legally valid for most everyday agreements, under laws such as the US ESIGN Act and the EU's eIDAS. Some documents — certain wills, deeds and court filings — still require wet ink, so check what applies to your document and jurisdiction.
Is my signature stored anywhere?
No. It's drawn and saved entirely in your browser, and nothing is uploaded to a server.
Why a transparent background?
So the signature sits directly over the document text rather than covering it with a white box. PNG is the format that supports transparency.
How do I add it to a PDF?
Most PDF readers, including Preview on Mac and Acrobat Reader, let you insert an image onto a page. Place the PNG where the signature line is and resize it.
Can I use it on my phone?
Yes — and it's usually better. Signing with a finger or stylus on a touchscreen looks much closer to your real signature than using a mouse.
