How to Safely Add a Logo to Your QR Code (Without Breaking It)
Adding a logo makes QR codes recognizable and beautiful — but if done wrong, they become unreadable. Our static generator supports centered image overlays with full control, and here’s exactly how to do it right.
The Golden Rules
- Logo must cover no more than 20% of the total QR area (15% is safer)
- Use a transparent PNG with simple shapes — avoid fine text or gradients
- Always increase error correction to Q or H when adding a logo
- Keep at least 4–6 modules of quiet zone around the entire code
- Center the logo perfectly — never offset
Why Error Correction Is Critical
A logo damages the underlying data modules. Level H can recover up to 30% damage, meaning even a bold logo in the center won’t break scannability. Level M (15%) is usually not enough for visible logos.
Best File Format & Preparation
Use a high-resolution transparent PNG (at least 500×500 px). Remove complex backgrounds. Simple icons (like brand marks) work far better than full photographs.
Real-World Testing Tip
After generating, test with multiple phones (iPhone, Android, old models) at different angles and distances. If it fails once, reduce logo size or increase error correction.
FAQ
Can I add text instead of a logo?
Only if it’s bold and high-contrast. Fine text almost always fails.
Is 25% coverage ever safe?
Rarely. Only with Level H, perfect printing, and ideal scanning conditions.
Should the logo have a white border?
Yes — a thin white padding (2–4 px) dramatically improves reliability.
A beautiful QR code that doesn’t scan is just a pretty square.
