Introduction

A QR Code (Quick Response Code) is a type of matrix barcode (or two-dimensional barcode) invented in 1994 by the Japanese company Denso Wave. The QR Code's main feature is its ability to store information both horizontally and vertically, allowing it to hold more data than traditional one-dimensional barcodes. QR Codes are widely used in various scenarios, such as payments, website links, product tracking, and more.

How to Use the Tool

  1. Enter Content: Input the information you want to encode in the "Content" input box.
  2. Set Colors: Choose the foreground and background colors to customize the appearance of the QR Code.
  3. Select Error Correction Level: Choose the error correction level (L, M, Q, H) to determine the QR Code's fault tolerance. The higher the level, the more damage or dirt the QR Code can tolerate.
  4. Adjust Other Parameters: Adjust the size, margin, minimum version, and other parameters of the QR Code as needed.
  5. Add Image: If desired, add an image to the center of the QR Code and set the related properties of the image.
  6. Generate QR Code: Once all settings are complete, the QR Code will be automatically generated and displayed on the page.
