• Foreground & background colors
• Linear or radial gradients (with rotation) on foreground and background
• Transparent background option
• Six dot styles: square, rounded, dots, classy, classy rounded, extra rounded
• Three corner-square styles and two corner-dot styles
• Logo overlay with size, margin, and "hide dots behind logo" controls
• Adjustable error correction (L / M / Q / H)
• Adjustable size and margin
• Export as PNG, SVG, JPEG, or WebP
• Liquid-glass UI with automatic light/dark mode

Run locally

Two options:

1. Double-click index.html — it works directly in your browser (no build step).
2. Serve the folder, e.g.:

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

The two QR libraries are loaded from jsDelivr. For fully offline use, download qrcode.min.js and qr-code-styling.js from jsDelivr and replace the CDN URLs in the <script> tags of index.html.

Why?

Most online QR generators are hosted services that track URLs, paywall styling features, or insert tracking redirects. This is the opposite:

• 100% client-side — your URL, settings, and logo image never leave your browser
• No analytics, no signup, no rate limits — generate as many as you like
• Open source (MIT) — fork it, embed it, modify it
