Guide & Terminology

What is a QR Code?

A QR code (Quick Response Code) is a two-dimensional barcode capable of storing various digital data such as URLs, text, and contact information. It can be read instantly by smartphone cameras and is widely used to guide users from offline to online.

How to Use

Data Input: Type or paste a URL or text into the input box to instantly generate and preview a QR code in real-time.
Customization: Adjust the "Error Correction Level" from the options.
Design Tweaks: Change the foreground and background colors to match your brand, and determine whether to include a quiet zone (margin).
Download: Once satisfied, download the generated QR code as an image (PNG).

Terminology

Error Correction: An algorithm that allows the QR code to remain readable even if it's partially covered, distorted, or damaged. Higher levels create denser patterns but offer more resilience.
Version: QR Codes range from Version 1 (21x21 modules) to 40 (177x177). Higher versions store more data.

Common Use Cases

Generating a scannable URL code to print on physical business cards or flyers.
Sharing long, complex Wi-Fi passwords visually with house guests.

Security

The QR code generation algorithm runs entirely within your browser (locally). The private text or URL you input is never transmitted to any external server.
