What Can You Encode in a QR Code?
A QR code can store several types of data that a phone camera can act on directly — opening a website, starting an email, dialing a number, joining a WiFi network, or opening a WhatsApp chat with a pre-filled message. Choose the type that matches what you need above.
How QR Codes Work
A QR code encodes data using a standardized grid pattern with built-in error correction, so it can still be read even if part of the code is damaged, dirty, or partially covered. This generator builds a genuine, standards-compliant QR code entirely in your browser.
