QR Code Generator

Generate QR codes for barcode scanner testing, development, and everyday use. Everything runs locally in your browser, so your QR content stays on your device.

Generate a QR Code

Create a scannable QR code for testing physical scanners, camera-based scanners, POS systems, and applications.

Generate a QR Code for Testing

Use this online QR code generator to create test data without sending it to an external service. Display the generated code on a screen or print it, then scan it with a physical barcode scanner, QR-capable scanner, camera-based scanner, POS system, or mobile application.

For keyboard-wedge workflows, scan the code into the Barcode Input Tester and verify the value, timing, and ENTER or TAB suffix behavior.

How to Test a QR Code Scanner

  1. Enter text or a URL and generate the QR code.
  2. Display it at a readable size or print it.
  3. Scan it with your physical scanner or camera-based scanner.
  4. Confirm the application receives the expected content.
  5. For keyboard-wedge scanners, verify the ENTER or TAB suffix in the input tester.

QR Code Testing Workflows

QR codes are useful test inputs for POS and retail systems, QA checks, web and desktop applications, mobile apps, and scanner hardware. Combine this tool with the Barcode Generator when a workflow must support both 1D barcodes and QR codes.

Learn how scanner input behaves in more detail in the Barcode Scanner Testing guide and HID keyboard wedge guide.
