The QR Code Generator is a powerful client-side tool that allows you to create QR codes for various purposes. Whether you need to share a website URL, contact information, or any text, this tool makes it easy to generate QR codes without sending any data to a server.

This guide explains what QR codes are, how they work, and walks you through using our free online generator to create customized QR codes for your projects.

📘 What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store various types of data. Unlike traditional barcodes that can only store information horizontally, QR codes store information both horizontally and vertically, allowing them to hold much more data in a smaller space.

QR codes were invented in 1994 by Denso Wave, a Japanese automotive company, to track vehicles during the manufacturing process. Today, they're used worldwide for countless applications.

🧩 QR Code Components

A QR code consists of several distinct elements:

  • Finder Patterns: The three large squares in the corners help scanners locate the QR code
  • Alignment Patterns: Smaller squares that help scanners adjust for image distortion
  • Timing Patterns: Lines of alternating dark and light modules that help determine the size of the data grid
  • Version Information: Specifies which QR code version is being used
  • Data Cells: The remaining black and white pixels that contain the encoded data
  • Quiet Zone: The blank margin around the QR code that helps scanners identify the code

📊 Error Correction Levels

QR codes include error correction capability to restore data if the code is damaged or partially obscured:

  • Level L (Low): 7% of data can be restored
  • Level M (Medium): 15% of data can be restored
  • Level Q (Quartile): 25% of data can be restored
  • Level H (High): 30% of data can be restored

Higher error correction levels make the QR code more reliable but also increase its complexity and size.
