Create custom QR codes with colors, logos, and high-resolution downloads
L=7%, M=15%, Q=25%, H=30% error recovery
QR (Quick Response) codes are 2D barcodes that can store URLs, text, contact info, WiFi credentials, and more. They're scannable by any smartphone camera and widely used in marketing, payments, and authentication.
QR codes have built-in error correction. Level L (7%) is fastest to scan, while Level H (30%) can be read even if 30% of the code is damaged - useful for codes with logos or decorative elements.
Ensure high contrast between foreground and background colors for reliable scanning. Test your QR code with multiple devices. Add a call-to-action like "Scan to visit" to increase scan rates.
