What Is the QR Code Generator?

This QR Code Generator lets you create customizable QR codes from any text or URL instantly. You can adjust the output size, foreground and background colors, and error correction level. The generated QR code can be downloaded as a PNG image or copied directly to your clipboard.

QR codes are two-dimensional barcodes that can be scanned by smartphones and dedicated readers. They are widely used for sharing URLs, contact information, Wi-Fi credentials, and other data quickly.

How to Create a QR Code

Creating a QR code takes seconds:

  • Type or paste your text or URL into the input field. The QR code generates automatically as you type.
  • Choose a size from the dropdown (128px to 1024px).
  • Select an error correction level. Medium (15%) is the recommended default.
  • Optionally customize the foreground and background colors using the color pickers.
  • Click Download PNG to save the image, or Copy Image to place it on your clipboard.

Understanding Error Correction Levels

QR codes include redundant data that allows them to be read even when partially damaged. The four error correction levels determine how much damage a code can tolerate:

  • Low (7%) — Smallest code size, least redundancy. Use when the QR code will always be displayed on a clean screen.
  • Medium (15%) — Good balance of size and reliability. Best for most use cases.
  • Quartile (25%) — Higher redundancy. Good for printed materials that may get scratched.
  • High (30%) — Maximum redundancy. Required if you plan to overlay a logo on the QR code.

Tips for Creating Effective QR Codes

  • Keep your URLs short. Shorter data produces simpler QR codes that scan faster and more reliably.
  • Maintain high contrast between foreground and background colors. Dark on light is most reliable.
  • Test your QR code on multiple devices before printing or publishing.
  • Use at least 256px for print materials and 512px or larger for posters and signage.

Common Use Cases

  • Business cards linking to a website or contact page.
  • Restaurant menus accessible via table QR codes.
  • Event tickets and check-in systems.
  • Product packaging linking to instructions or warranty registration.
  • Marketing materials with trackable URLs.
