It is not quite that simple.
Most compression algorithms expect the
input to be characters from some alphabet, such as 8-bit bytes. Base64
changes that, the bytes are not really visible. However, many of the
input formats do not use bytes anyway, they are more properly seen as
bit strings composed of variable length tokens. It does not really
matter whether a compression algorithm sees six of eight bits from the
middle of that string, when it cannot even tell where each token
ends.
Au this point you can think of ways to turn six back to eight.
But does it really matter to anyone?
