How to Generate a QR Code Online for Free
QR codes bridge the physical and digital world — a printed code on a menu, poster, or business card that instantly opens a URL on any smartphone. This guide shows you how to create a customised, high-resolution QR code in seconds using a free tool that runs entirely in your browser.
Understanding Error Correction Levels
QR codes can still be read even when partially damaged or obscured, thanks to built-in error correction. Four levels are available:
- L (Low) — 7% recovery: Smallest code, best for clean digital displays
- M (Medium) — 15% recovery: Good balance for most uses
- Q (Quartile) — 25% recovery: Recommended for printed materials that may get worn
- H (High) — 30% recovery: Best for QR codes with a logo overlaid in the centre
Step-by-Step Instructions
Open the QR Code Generator
Navigate to the free QR Code Generator. The tool runs locally in your browser — your data is never sent to a server.
Enter your URL or text
Paste a full URL (including https://), or type any text: a phone number, email address, plain text message, or geo-coordinate. The QR updates as you type.
Choose size and error correction
Pick 256px for most uses (sharp on screen and print at small sizes), or 512px for large-format print. Use Q or H error correction if the QR will be printed on textured surfaces or have a logo overlay.
Customize colors
Change the foreground color to your brand color and keep the background white or light for reliable scanning. Dark-on-light always scans better than light-on-dark.
