QR Code Generator

A dead simple, single-file QR code generator. Everything runs client-side in the browser — nothing you type is ever uploaded anywhere.

Features

• Generate a QR code from any text or URL, live as you type
• Adjustable size, quiet zone (margin), and error correction level
• Custom foreground/background colors
• Download as PNG or SVG
• Fully offline & self-contained — no CDN, no network requests, no tracking

Run locally

Just open index.html in a browser. No build step, no dependencies to install.

Or serve it with any static file server:

python3 -m http.server
# then visit http://localhost:8000

Deploy to GitHub Pages

1. Push this repo to GitHub.
2. Go to Settings → Pages.
3. Under Build and deployment, set Source to Deploy from a branch.
4. Pick your branch (e.g. main) and the / (root) folder, then Save.
5. Your generator will be live at https://<username>.github.io/<repo>/.

How it works

QR matrix generation uses the tiny, vendored qrcode-generator library (qrcode-generator.min.js, ~20 KB). The canvas/SVG drawing, colors, and UI are plain HTML, CSS, and vanilla JavaScript in index.html. There are no build steps and no external requests.
