What is QR Code Generator?

QR Code Generator is a free online tool that creates scannable QR codes from various types of content. QR (Quick Response) codes are two-dimensional barcodes that can store URLs, text, WiFi credentials, email addresses, and phone numbers. They can be scanned by any smartphone camera.

How to Use QR Code Generator

Select the content type (URL, Text, WiFi, Email, or Phone) from the tabs at the top. Fill in the required fields for your chosen type. Customize the QR code foreground and background colors using the color pickers. Adjust the size with the slider. The QR code preview updates in real time. Click "Download PNG" to save your QR code.

How QR Code Generator Works

The tool encodes your input data into a QR code matrix using the Canvas API. It renders the QR pattern as a grid of dark and light modules on an HTML canvas element. Custom colors are applied to the foreground (modules) and background. The result can be downloaded as a PNG image.

  • Create QR codes for website URLs to share on printed materials
  • Generate WiFi QR codes for easy guest network access
  • Make QR codes for email addresses on business cards

Frequently Asked Questions

What types of content can I encode in a QR code?▼

You can encode URLs, plain text, WiFi network credentials, email addresses, and phone numbers. Each type uses a specific format that devices recognize automatically when scanned.

Can I customize the colors of my QR code?▼

Yes. You can change both the foreground (dark modules) and background colors. Ensure there is enough contrast between the two colors for reliable scanning.

What size should my QR code be?▼

For print, a minimum of 2 cm x 2 cm is recommended. For digital use, 200x200 pixels works well. The tool lets you adjust the size from 200 to 600 pixels.

Are the QR codes generated permanently valid?▼

Yes. The QR codes are static — the data is encoded directly in the image. They do not expire or require any online service to work.
