[Online Tool] Create an Electronic Signature Online — Transparent PNG Ready to Drop into Word

Sending contracts, submitting application forms, signing off on approval documents… more and more situations call for a signature, but there's no paper at hand, and printing just to scan it back in is a waste of everyone's time.

Toolshu's Electronic Signature Maker generates signature images two ways — draw by hand or type your name and auto-generate — and downloads as a transparent-background PNG that drops straight into Word or PDF, just like signing on paper. All processing runs locally in your browser; no data is uploaded.

Two Ways to Create Your Signature

Draw mode: Use your mouse to write on the drawing canvas — or use a finger or stylus on a touchscreen. The tool includes a stroke-weight algorithm that automatically adjusts line thickness based on writing speed, producing natural variation between thick and thin strokes rather than a flat, uniform line. The result is much closer to the feel of a real handwritten signature.

Customize pen color and thickness, undo strokes one at a time, or clear the canvas entirely and start over.

Text generation mode: Not happy with your own handwriting? Type your name, select a calligraphy font, and click Generate — the tool produces a signature that looks handwritten. Built-in font styles include Running Script (recommended), Flowing Cursive, Longcang, Calligraphy Kaishu, and Standard Kaishu.

Two Download Formats

Transparent PNG (strongly recommended): Ink only — the background is completely transparent. When inserted into Word or PDF, the signature overlays directly on the content with no white rectangle blocking anything underneath. It looks like it was signed directly on the page.

White-background JPG: Includes a white background — suitable for printing or when a document specifically requires JPG format.

Privacy and Security

All drawing and image generation happens locally in your browser. Your signature image is never uploaded to any server. Close the browser and the signature is gone — nothing is stored in the cloud.

Does This Signature Have Legal Validity?

The signature produced by this tool is an image-based electronic signature — fundamentally, it's a picture.

In many countries and regions, electronic signatures carry legal weight. For ordinary contracts, approval forms, and internal process documents, this is completely sufficient. However, for critically important legal documents — property transaction contracts, wills, and similar — it's advisable to consult a professional or use an electronic signature platform with a digital certificate.

For everyday contracts, expense claims, and application forms, this tool is more than enough.
