QR Code Generator

You've designed the perfect business card. Clean, minimal, professional. Now you need to add your contact info. Your name, company, email, phone, website, LinkedIn... suddenly that elegant design is cluttered with tiny text that nobody wants to type.

One QR code replaces all of it. A single scan instantly opens your website, saves your contact card, or connects to your WiFi network. No typing, no typos, no friction.

This generator creates high-quality QR codes in seconds—ready for print, digital, or anywhere you need instant information transfer.

What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. Unlike traditional barcodes that hold ~20 characters, QR codes can store over 4,000 characters—enough for URLs, contact cards, WiFi credentials, and more.

How it works:

- Finder patterns (corners): Help scanners locate and orient the code
- Alignment patterns: Correct for distortion
- Data modules: Encode the actual information
- Error correction: Allow scanning even when partially damaged
