I built a free browser-based QR and barcode generator with local-only rendering

I built QR Barcode Kit as a small browser-based toolkit for creating static QR codes and common barcode formats without uploading data to a server.

The tool currently supports:

  • URL QR codes
  • WiFi QR codes
  • vCard QR codes
  • General barcode generation
  • Code 128 barcodes
  • EAN-13 barcodes

The main reason I built it this way is privacy and speed. The generated code is rendered locally in the browser, so the input does not need to be sent to an account-based dashboard or backend API.

Useful pages:

I am keeping the project simple: free static QR codes, practical barcode formats, no login, and no scan tracking.
