A higher ECL count means the QR code can take more damage, but increasing the ECL will also increase the code size. The ECL ensures that more data modules (backed-up data) are included in the code.

It then takes the selected code and shows you how it is put together. Fun fact: 21×21 “modules” (QR-speak for pixels) is the size of a version 1 QR code. Each version increases the size by ...
