Yes. A logo can be placed inside a QR code and the code will still scan. The reason this works is deliberate — QR codes include error correction redundancy specifically to tolerate module damage and obstruction. A logo placed in the center of a QR code obstructs some modules. The redundant data elsewhere in the code supplies the missing information. The code still scans.
The Error Correction That Makes It Possible
At error correction level H — the highest level — a QR code can tolerate up to 30 percent of its modules being damaged or obscured. A logo occupying 30 percent of the code's area is at the absolute upper limit. In practice, logos should occupy no more than 20 to 25 percent of the code area to maintain a reliable scan margin.
Codes generated at lower error correction levels — L (7%) or M (15%) — cannot support a significant logo without failing to scan. Always use error correction level H when embedding a logo.
Where to Place the Logo
Center placement is standard and most effective because the center of a QR code contains a relatively lower density of critical data modules than the corners where the finder patterns live. Placing the logo in the center rather than over a corner finder pattern maximizes scan reliability.
Never cover a finder pattern with a logo. The three corner squares are the scanner's orientation anchors. Obstructing any part of a finder pattern causes reliable scan failure regardless of error correction level.
Contrast Still Matters
The logo itself should not interfere with module contrast. A logo with a white background placed in the code center is least disruptive. A logo with complex colors that bleed into adjacent modules can reduce contrast enough to cause scanning issues even when the covered area is within the error correction tolerance.
Test Before Printing
Every logo QR code combination should be test scanned before printing. The theoretical 30 percent tolerance is measured under ideal conditions — good lighting, proper size, correct orientation. Real-world conditions reduce the practical margin.
