About QR codes

QR codes encode short strings — URLs, vCards, WiFi credentials — into a 2D barcode that any phone camera can read. This tool generates and decodes them locally; nothing is uploaded.

  • Use short URLs to keep codes scannable.
  • High contrast (dark on white) scans best.
  • WIFI:, mailto:, tel:, geo: work natively on mobile.
  • Generation and scanning happen entirely in your browser.
