What are QR mask patterns?

The QR code spec defines 8 mask patterns (0–7) that are XOR'd over the data modules to improve scannability. Auto lets the library pick the spec-optimal mask using the QR penalty scoring rules (N1–N4), which minimises large runs of same-colour modules and avoids awkward visual patterns. Picking a specific mask lets you choose the one that looks most balanced for your content and colours.

Error correction levels explained

Level L (7%) is the most compact. Level M (15%) is standard for most uses. Level Q (25%) is good for codes that may get dirty when printed. Level H (30%) gives maximum damage resistance and allows logo overlays on the QR pattern.

Privacy — generated in your browser

QR codes are generated locally using the open-source qrcode library. Your URLs, WiFi passwords, and text are never sent to any server. The PNG is created from a browser canvas element and downloaded directly.

Frequently Asked Questions

Will the QR code scan with a phone camera?

Yes. The qrcode library generates fully spec-compliant QR codes. Black on white at Level M or higher works reliably with all modern smartphone cameras.

Does the mask pattern affect scannability?

All 8 mask patterns produce equally valid, scannable QR codes. The mask only affects the visual appearance of the data modules, not the encoded data.

What download size should I use?

512px is fine for most digital uses. Use 1024px or 2048px for print — a 2048px file can be printed at 8×8 inches at 256 DPI without loss of sharpness.

What is the WiFi QR code format?

WiFi QR codes use the standard WIFI:T:WPA;S:NetworkName;P:Password;; format, supported by iOS 11+, Android 10+, and most camera apps.

Can I use a coloured QR code?

Yes — use the quick color presets or the custom color pickers. Ensure high contrast between foreground and background for reliable scanning.
