QR Code Generator
Generate scannable QR codes for text or URLs, with contrast validation, capacity feedback, and PNG download.
QR code settings
Generate on demand Scanning tips. Keep dark modules on a light background, leave a visible quiet zone, and keep high
contrast. Very long text can exceed the capacity of the chosen error-correction level; the tool explains when that
happens instead of producing an unscannable code.
The QR renderer is loaded only when you generate a code. Nothing you type is uploaded, and the PNG is created locally from the preview canvas.
About QR Code Generator

This tool runs locally in your browser. It does not upload your input, require an account, or store your data on a server. If a feature needs a network request, the interface asks before sending anything.
