How to Add a Logo to a QR Code Without Breaking Scan Reliability

Adding your company logo to a QR code builds trust, reinforces brand identity, and increases scan rates by up to 30%. However, because a logo literally covers up QR modules, improper implementation can make your code completely unscannable.

The Golden Rules of Logo QR Codes

1. Always Use Error Correction Level Q or H Standard QR codes use Level M error correction (~15% recovery). When you insert a logo in the center, you consume that error margin. To ensure the code remains readable even under dim lighting or slight lens blur: - Use **Level Q** (25% recovery) or **Level H** (30% recovery). - QR Studio automatically promotes your error correction when you upload a logo!

2. Keep Logo Size Under 28% of Total Width The logo should occupy between 15% and 25% of the QR code's central area. Never let the logo touch or overlap the three large corner finder patterns.

3. Use a Clear Margin / Background Pad Surrounding your logo with a solid background margin (quiet buffer) ensures that the intricate details of the logo don't visually merge with the surrounding QR dot patterns.

4. High Contrast and Vector Quality Always upload high-resolution transparent PNG, WebP, or SVG graphics. Ensure the colors in your logo do not clash with the QR foreground modules.
