To generate a branded QR code with a centered logo, encode the URL using an appropriate error-correction level and composite the resized logo onto a white background in the center to preserve scannability. The final image is saved to your requested output path.

Adding an image overlay to a QR code requires error correction because the center logo obscures data modules. Selecting a higher error-correction level ensures the QR code remains scannable even with the visual obstruction blocking part of the pattern.

Yes, you can use Python and Pillow to composite a custom image onto a QR code. The process uses the qrcode library for generation and Pillow to resize the overlay, composite it on a white background for contrast, and save the final image file.

You need to install the Pillow library and the qrcode package to create QR codes with image overlays. Pillow handles image resizing and compositing, while qrcode generates the base scannable URL encoding with configurable borders and error correction.

The best way to keep a branded QR code scannable when compositing a logo is to render the overlay on a white background. This improves readability and contrast while using a higher error-correction level compensates for the obscured data.

The limitation of overlaying a large image in the center of a QR code is that it obscures too much data, risking scan failure. You must balance the logo size against the error-correction capacity to ensure the QR code remains reliably scannable.
