signature generator

How to use the signature generator

  1. Pick a mode: Draw (sketch with mouse, trackpad, or touch), Type (choose from 20+ signature-style fonts), or Upload (drop an existing signature image to clean up the background).
  2. In Draw mode: adjust stroke color, thickness (0.5-4px), and smoothing to soften shaky lines. Use the eraser and undo buttons freely.
  3. In Type mode: type your full name and cycle through handwriting fonts — Great Vibes, Alex Brush, Sacramento, Dancing Script. Adjust size and slant.
  4. Preview the signature on a transparent background or pick a solid color for documents that require opaque signatures.
  5. Download as transparent PNG (best for documents), SVG (scalable for print), or JPG (for email signatures where PNG isn't supported).

When to use it

Use Draw mode when you need a real signature that looks authentic — PDF contracts, DocuSign uploads, legal documents. Use Type mode for email signatures, blog post sign-offs, and casual branding where an exact handwritten match isn't required. Use Upload mode to extract a clean transparent signature from a scanned page — the tool removes white/paper backgrounds automatically. Alternative: DocuSign has a draw tool but requires signup, document upload, and a paid plan for standalone signature export.

Example

Email signature use case: type your name in Alex Brush at 48px, export as transparent PNG, paste into your email client's signature settings. Works in Gmail, Outlook, Apple Mail.

PDF contract use case: draw with a touch device, export as transparent PNG at 300 DPI, upload into Adobe Acrobat's Fill & Sign or DocuSign. The transparent background lets the signature overlay any form field cleanly.

Frequently asked questions

Is a digitally-generated signature legally binding?
In most jurisdictions (US ESIGN Act, EU eIDAS Simple Electronic Signature tier), a typed or drawn signature attached to an intent to sign is binding for routine business documents. High-stakes use cases (real estate, medical, government forms) often require qualified electronic signatures with identity verification — use DocuSign or Adobe Sign for those.
Does the signature look handwritten enough for PDFs?
Draw mode produces real handwriting; the output matches whatever you sketch. Type mode uses handwriting fonts that look convincing at 48-72px and professionally styled, not machine-printed.
How do I get a transparent background?
Export as PNG (not JPG). PNG supports transparency; JPG doesn't. The tool preserves transparency by default; confirm the file is saved as .png.
Can I resize the signature without quality loss?
Export as SVG for truly infinite scaling. PNGs scale cleanly down but pixelate when enlarged beyond the export size.
Is my signature saved anywhere?
No. The tool runs entirely in your browser — the signature never leaves your device and isn't stored on our servers.
Can I use this on my phone?
Yes. Draw mode works with touch input on iOS and Android. Type and Upload modes work on any device.
What DPI should I export at?
300 DPI for print-ready documents (contracts, certificates). 72 DPI (the default) is fine for email, web, and on-screen PDF signing.
