Type a link or any text — the QR code appears instantly. Pick a size, download the PNG. Nothing leaves your browser.
Higher = more damage-resistant, denser code
Type something to generate a QR code.
Is my link uploaded anywhere?
No. The QR code is computed entirely in your browser (open-source MIT library, bundled — no CDN, no tracking). Your text never leaves your device.
What does error correction do?
QR codes carry redundancy so they scan even when partially covered or damaged. L tolerates ~7% damage, M ~15%, Q ~25%, H ~30%. Higher levels make the code denser — M is the everyday default.
Print quality?
The PNG is rendered pixel-perfect at your chosen size with a proper quiet zone. For print, pick 1024px.
