What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that stores data — URLs, text, contact info, WiFi credentials, and more. Unlike traditional barcodes that only hold numbers horizontally, QR codes encode data in both directions, allowing phones and scanners to read them instantly from any angle. This free QR code generator creates custom codes in your browser using the qrcode library — no data ever leaves your device.

How QR Codes Work

  1. Data encoding — your text or URL is converted into a pattern of black and white modules.
  2. Error correction — redundant data is added so the code still scans if partially damaged or covered.
  3. Position markers — the three large squares in the corners help cameras orient and decode the QR.
  4. Scanning — any modern phone camera or QR scanner app decodes the pattern back to your original data.

How to use QR Code Generator

  1. Choose a QR type (URL, WiFi, email, phone, SMS) and enter your content.
  2. Adjust size, colors, margin, and error correction to match your needs.
  3. Download as PNG for digital use or SVG for print-quality vector output.

QR Code Design Tips

  • Keep high contrast — dark foreground on light background scans reliably. Avoid pastel-on-pastel or low-contrast color combinations that confuse phone cameras.
  • Use SVG for print — the SVG format scales to billboard size without pixelation. PNG is fine for screens but blurs when enlarged for print materials.
  • Add margin for scanning — a 2-4px margin gives phone cameras a clear quiet zone around the QR code, improving scan speed and reliability.
  • Test before printing — scan your generated QR from the screen AND from a test print. Different lighting and paper types affect scan reliability.
