Signature generator

Draw or type your signature and download it as a transparent PNG — trimmed, crisp, and never uploaded anywhere.

Create your signature by
Ink color

The PNG has a transparent background, trimmed to your signature — ready to place into documents and email footers, or straight onto a page with the sign-PDF tool.

Your signature never leaves your browser — it is drawn and saved on your device.

Draw your signature — mouse, finger, or stylus — or type your name in a handwriting style, and download a transparent, trimmed PNG ready to drop into contracts, PDFs, and email footers. Created and saved entirely on your device.

How to create your signature

  1. Pick Drawing (natural, unique) or Typing (fast, tidy) and an ink color.
  2. Draw on the pad — Clear restarts — or type your name and choose a style.
  3. Download: the PNG comes trimmed to your signature with the background transparent.

Draw or type?

A drawn signature is yours — unique, familiar, and what most people want on anything semi-formal; big slow strokes on a touchscreen give the best result. Typed signatures are the quick, consistent option for routine paperwork: pick a style, and every download is identical. Both produce the same kind of file — transparent PNG, black or blue ink — so the choice is purely about how the mark should look.

What the transparent PNG buys you

An opaque white-background signature image looks pasted-on the moment it overlaps a line, box, or shaded area of a form. Transparency means only the ink lands on the page — it sits on signature lines naturally, exactly like ink. The automatic trim removes empty canvas so the file places at a predictable size, and the 2× rendering keeps strokes crisp when scaled. Pair it with the watermark tool for marking documents, or JPG to PDF to turn signed pages back into documents.

Private by design

A signature is an identity credential — the last thing to hand to an unknown server. This generator runs completely in your browser: nothing you draw or type is transmitted, logged, or retained anywhere.

Frequently asked questions

Is the background really transparent?
Yes — the PNG contains only your ink strokes on a transparent background, automatically trimmed to the signature itself with a small margin. Dropped onto any document, only the signature shows.
Drawing with a mouse looks shaky — any tips?
Draw large and slow — the pad smooths strokes, and the trimmed PNG scales down cleanly, which visually tightens wobble. A phone or tablet finger/stylus usually beats a mouse; the pad works with touch on this same page.
Is a generated signature legally valid?
In many jurisdictions (e.g., under the US E-SIGN Act or eIDAS in the EU) simple electronic signatures — an image of your signature placed with intent to sign — are broadly valid for everyday agreements, but requirements vary by document type and country, and some documents demand certified digital signatures. When it matters, confirm what the receiving party accepts.
Why does the typed style look different on my phone vs my laptop?
Typed mode uses handwriting fonts already on your device, so rendering varies slightly across systems. The preview you see is exactly what downloads — draw mode is identical everywhere.
Is my signature uploaded or stored?
No. It is drawn, rendered, and saved entirely on your device — a signature is exactly the kind of thing that should never sit on someone's server.
