Generates a QR code for arbitrary text, URL, vCard, WiFi string and so on. All four error-correction levels supported (L/M/Q/H — from ~7% to ~30% redundancy) and versions 1–40 (up to ~2900 bytes). Choose foreground and background color, module size and margin. Export to PNG (for print or messengers) or SVG (scales without loss). Encoding happens in the browser; nothing leaves your device.
