What is a QR Code?

A QR (Quick Response) code is a two-dimensional matrix barcode invented in 1994 by Denso Wave, a Japanese automotive company. Unlike traditional one-dimensional barcodes that can only hold about 20 digits, QR codes can store thousands of characters including numbers, letters, and special characters.

QR codes use a grid of black and white squares arranged in a specific pattern. Three distinctive square markers in the corners help scanners detect and orient the code. The data is encoded using Reed-Solomon error correction, which allows the code to be read even if portions are damaged or obscured.

Error Correction Levels Explained

QR codes include built-in error correction using Reed-Solomon codes. Higher error correction makes the code more resilient but increases its size:

LevelRecovery RateBest For
L (Low)~7% data recoveryClean digital displays, maximum data capacity
M (Medium)~15% data recoveryGeneral purpose, good balance of size and resilience
Q (Quartile)~25% data recoveryPrinted materials, outdoor signage
H (High)~30% data recoveryIndustrial use, harsh environments, logo overlays

Tips for Better QR Codes

  • Contrast matters: Use dark foreground on light background for best scan reliability. Avoid similar or low-contrast color combinations.
  • Size considerations: Larger QR codes are easier to scan from a distance. For printed materials, ensure the code is at least 2cm x 2cm.
  • Test before printing: Always scan your QR code with multiple devices before printing or distributing.
  • Keep data short: Shorter data produces simpler QR codes that are faster and more reliable to scan.
  • Use URL shorteners: For long URLs, consider using a URL shortener first to create a simpler QR code.

Privacy & Security

Frequently Asked Questions

What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that stores information in a matrix of black and white squares. It can encode URLs, text, WiFi credentials, contact information, and more. QR codes can be scanned using smartphone cameras or dedicated QR code reader apps.

Is this QR Code Generator free to use?

Yes, this QR Code Generator is completely free. It generates QR codes entirely in your browser using JavaScript, so no data is sent to any server. You can create unlimited QR codes and download them as PNG images at no cost.

What error correction level should I choose?

Error correction allows a QR code to be read even if partially damaged. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Use L for clean digital displays, M for general use, Q for printed materials, and H when the QR code may be partially obscured or damaged.

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

You can encode plain text, URLs/websites, WiFi network credentials (network name, password, and encryption type), email addresses (with optional subject and body), and phone numbers. Each content type uses standardized formats that smartphones can automatically recognize and act upon.

Can I customize the colors of my QR code?

Yes, you can customize both the foreground (dot) color and background color. Ensure sufficient contrast between foreground and background for reliable scanning. Dark foreground on light background works best. Avoid using very similar colors as this may prevent successful scanning.
