Frequently Asked Questions
QR (Quick Response) code is a 2D barcode that stores information like URLs, text, contact details, or WiFi credentials. Smartphones can scan QR codes with their camera to quickly access the encoded data.
Error correction allows QR codes to be readable even when partially damaged or dirty. L=7%, M=15%, Q=25%, H=30% damage tolerance. Higher levels make codes more robust but also larger and more complex.
You can encode any text: URLs, plain text, email addresses, phone numbers, WiFi credentials, vCard contact info, geographic coordinates, or even small files as base64. QR codes can store up to ~4,000 characters.
This tool allows you to customize size and error correction level. For advanced customization (colors, logos, rounded corners), you can use specialized QR code designers after downloading the base code.
