What is QR Code Generator?

QR Code Generator emits a scalable SVG QR code from URL/text payloads or structured WiFi configurations. Pick an error-correction level (L=7%, M=15%, Q=25%, H=30%) — higher means the code survives more damage at the cost of denser modules. WiFi mode accepts JSON `{"ssid":"…","password":"…","encryption":"WPA|WEP|nopass","hidden":false}` and emits the standard `WIFI:T:WPA;S:…;P:…;;` URI format that iPhone and Android cameras read automatically. This tool is part of santekno's developer toolbox — a curated collection of utilities built for engineers who care about speed, privacy, and simplicity.

Common use cases

  • Debugging API payloads and integration issues
  • Inspecting tokens, hashes, or encoded strings during development
  • Generating fixtures and sample data for tests
  • Sharing readable output with teammates in code reviews

FAQ

M (15%) is a good default. Use Q or H only if the code will be printed on something that may scuff — e.g., stickers, business cards.
