A QR code with a photo or a logo sitting in its centre looks impossible: surely covering the pattern should stop it working. In practice a well-made image code scans perfectly, and ChromaCode is our take on blending a picture into the symbol while keeping it reliable. Here is why it works and how to use it without breaking the scan.
Why an Image in the Middle Is Safe
The secret is error correction. Every QR code carries extra data that lets a reader reconstruct the original message even when part of the grid is missing or damaged. The higher the level, the more of the symbol can be obscured. Because the important finder patterns sit in the corners, the centre is the safest place to put an image — you are sacrificing modules the reader can afford to lose.
How to Use the ChromaCode Feature
The flow is short:
- Enter your content — a URL, text, Wi-Fi or any other type;
- Upload an image — a logo, portrait or product shot;
- Choose the strength — a higher error-correction level allows a larger or bolder image;
- Tune colors — keep the pattern dark on light so the reader still separates modules;
- Preview and download — export a PNG for screens or an SVG for print.
Choosing Images That Keep Contrast
Not every picture survives the blend. The rules that matter:
- High contrast images read best; washed-out or very pale art can vanish into the background;
- Simple, central subjects work better than busy edges that fight the modules around them;
- Avoid extremely dark images on a light background, or the whole code looks like one solid block;
- Keep the quiet zone — leave the empty margin around the code untouched by artwork.
Always Test an Image Code
Because the margin for error is thinner than a plain code, an image code deserves a real test on more than one phone and in the exact lighting where it will be used.
