QR Code Anatomy and Best Practices

QR (Quick Response) codes are two-dimensional barcodes invented in 1994 by Denso Wave. They can store significantly more data than standard 1D barcodes and can be scanned from any angle.

Error Correction Levels (L, M, Q, H)

QR codes use Reed-Solomon error correction to restore data if the code is dirty or damaged. Level L (Low) recovers 7% of data and is best for clean environments or dense codes. Level H (High) recovers up to 30%, which is necessary if you intend to place a logo in the center of the QR code.

The Quiet Zone (Margin)

A QR code requires a blank margin (quiet zone) around its border so scanners can distinguish it from its surroundings. The standard requires a 4-module (block) wide quiet zone. Removing it often makes the code unscannable.

Contrast and Color

While QR codes don't have to be black and white, contrast is critical. Scanners look for dark modules on a light background. Inverting the colors (light modules on a dark background) works in modern scanners but will fail on older laser scanners.

Common questions

Frequently asked questions

Is there a limit on how much text I can encode?

QR codes have a maximum capacity, and very long text will make the pattern denser and require a larger printed size to remain scannable.

Does encoding my data upload it anywhere?

No, the QR image is generated entirely client-side in your browser tab.
