signature generator
How to use the signature generator
- 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).
- In Draw mode: adjust stroke color, thickness (0.5-4px), and smoothing to soften shaky lines. Use the eraser and undo buttons freely.
- In Type mode: type your full name and cycle through handwriting fonts — Great Vibes, Alex Brush, Sacramento, Dancing Script. Adjust size and slant.
- Preview the signature on a transparent background or pick a solid color for documents that require opaque signatures.
- 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.
