How to Use This Calculator
- Select a QR code version (1-10). Higher versions create larger symbols that hold more data.
- Choose an error correction level (L, M, Q, or H). Higher correction recovers more damage but reduces data capacity.
- View the maximum data bytes available in byte mode and the total module count.
- Use this to determine if your data fits in a given QR version before generating codes.
