Wikipedia says :
In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an unencoded representation would use, through use of specific encoding schemes.
So be it.
Compression ? In my CPC ?
More often than you may believe.
The power of CrossDev
It was common to use a 16 bit computer like an Atari ST to get stronger compression. Today it is possible to get various compressors which are running on a PC platform and produce binary files which can be decompressed on Z80 computers.
Xyphoes Fantasy is a noteable example. The data is compressed and it was generated on an Atari ST.
Examples for modern CrossDev compression programs with Z80 decompression routines are
