How to add a logo to a QR code without breaking it
Choose error correction, logo size, contrast, and verification steps that preserve readability.
Quick answer
A logo hides QR modules, so it always reduces the reading margin. Start with strong contrast, a small centered logo, a light buffer around it, and the logo-oriented correction setting.
Step by step
Generate a plain QR first and verify it. Add the logo at the smallest useful size, avoid the three large corner markers, verify again, and only then add decorative dots or colors.
Common mistakes
A transparent logo can become unreadable over dark modules; a large white plate can erase too much data; and visual balance is not evidence of scan reliability.
Completion check
Decode the generated image before download, then test the final print or screen on different phones and in realistic light. Remove or shrink the logo if any test is unreliable.
