And it is not that bad - base45 packages nicely in 11 bits; so compared to exactly the same payload in binary - there is just a few percent difference in the end in pixels/cells on screen.

4 bytes get converted to 6 alnums and those gets packed into 3 * 11 = 33 "qr-bits" <=> [33/32 - 1] ~ 3% loss.
