What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can store various types of information, including text, URLs, contact details, WiFi credentials, and more. QR codes were invented in 1994 by Denso Wave, a Japanese company, and have since become one of the most popular ways to share information quickly and efficiently.
Unlike traditional barcodes that can only store a limited amount of data, QR codes can hold up to 4,296 alphanumeric characters, making them incredibly versatile for modern digital communication. They can be scanned by any smartphone camera, making them accessible to billions of users worldwide.

Best Practices for QR Codes
Choose the Right Error Correction Level
Use higher error correction levels (Q or H) for QR codes that will be printed or displayed in challenging conditions. Lower levels (L or M) work well for digital displays.
Ensure Proper Contrast
Maintain high contrast between the QR code color and background. Dark codes on light backgrounds or light codes on dark backgrounds work best for reliable scanning.
Test Before Distribution
Always test your QR code with multiple devices and scanning apps before printing or sharing. This ensures compatibility across different platforms and devices.
Provide Context
Include text near your QR code explaining what users will find when they scan it. This increases trust and improves scan rates.
Optimize for Print
When printing QR codes, ensure they're at least 2cm x 2cm (0.8" x 0.8") in size. Use high-resolution images and avoid compression that might degrade the code quality.
Frequently Asked Questions
Are the QR codes generated here free to use?
Yes, absolutely! All QR codes generated with our tool are completely free to use for personal or commercial purposes. There are no hidden fees, subscriptions, or usage limits.
Do you store or track my QR codes?
No, we don't store, track, or have access to any QR codes you generate. All processing happens locally in your browser, ensuring complete privacy and security of your data.
What's the difference between error correction levels?
Error correction levels determine how much of the QR code can be damaged or obscured while still remaining scannable. Level L (Low) can recover ~7% damage, M (Medium) ~15%, Q (Quartile) ~25%, and H (High) ~30%. Higher levels create denser codes but are more resilient.
Can I use custom colors for my QR code?
Yes! You can customize both the QR code color and background color. However, ensure there's sufficient contrast between the two colors for reliable scanning. We recommend testing your colored QR codes before final use.
What file format are the QR codes saved in?
QR codes are downloaded as PNG images, which provide high quality and are compatible with all major image editing software and printing services. PNG format ensures your QR codes remain crisp and scannable at any size.
Can I generate QR codes for WiFi networks?
Yes! Our generator supports WiFi QR codes. Simply select the WiFi option, enter your network name (SSID), password, security type, and whether it's a hidden network. The generated QR code allows users to connect to your WiFi network instantly by scanning.
