miji.beA QR code logo is a brand image or icon placed in the center of a QR code, overlaying some of the data modules. This is possible because QR codes' error correction capability can compensate for the obscured area, allowing the code to be read despite the logo covering part of the pattern.
To successfully embed a logo, the QR code must use a high error correction level (typically H, which tolerates up to 30% damage). The logo should cover no more than 20-25% of the code area to leave sufficient margin for error correction. The logo should be placed in the center, away from the finder patterns and alignment patterns that are critical for scanning.
Using a short URL as the encoded data is especially beneficial when adding a logo, because the shorter data requires fewer modules, leaving more room for error correction redundancy. This combination of short URL + high error correction + centered logo produces a branded, scannable QR code.
Best practices include using a simple, high-contrast logo, adding a white border around the logo to separate it from the QR modules, and testing extensively across different devices and scanning conditions.
