QR code with logo
A recognizable mark in the center makes a QR code yours. That is fine as long as scanners still see enough of the pattern. Scanmelon keeps a light zone for that.
Why a logo works
QR codes have built-in error correction. A small, calm icon in the center is allowed. People recognize your brand before they scan, which lowers the barrier on a poster or pack.
File and format
Upload PNG, JPG, SVG, or WebP, preferably under 2 MB. A simple pictogram or wordmark on a transparent background reads cleaner than a busy photo. Keep the logo smaller than the free area: too large and the camera misses modules.
Color and contrast
Dark modules on a light background remain the safe choice. A bright brand color is fine if the contrast stays high. Always test on a real phone, including dim light. Steps: Create a QR code. Upload in the generator via QR code generator.
