How to Create Custom QR Codes with a Logo in the Center

Adding a Logo

OmniQRHub allows you to seamlessly embed your company's logo directly into the center of the QR code. But how does this work without breaking the code?

Error Correction is the Key

QR codes have built-in redundancy known as Error Correction. By setting the Error Correction Level to 'High' (Level H), the QR code can sustain up to 30% damage or obstruction and still be perfectly readable. We utilize this mathematical redundancy by intentionally obscuring the center of the code with your logo, while ensuring the data remains fully intact.

Best Practices

• Keep it Simple: Use a clear, high-contrast logo.
• Watch the Size: The logo shouldn't take up more than 25% of the total QR code area.
• Test Before Printing: Always scan the customized code with multiple devices before sending it to the printer.

Why a Logo Doesn't Break the Code

QR codes contain error correction: extra data that lets a scanner rebuild parts of the code that are missing or damaged. When you add a logo, OmniQRHub switches to the highest level (H), which can recover up to about 30% of the code. The logo covers roughly 5% of the area in the centre, well within that margin.

Logo Tips That Keep Codes Scannable

• Use a simple, square mark such as your icon or monogram, not a long wordmark.
• Use a transparent PNG or an SVG. We place it on a small white tile so it stays readable on any colour.
• Keep contrast high. A dark code on a light background matters more than the logo. The generator warns you if the colours are too close.
• Keep the content short. Error correction makes the code denser, so a short URL leaves more room for the logo.
• Test before printing with at least two phones, one of them older.
