That is actually what compilation means.
Here, we start with Java byte code which isn't exactly human-readable, hence the use of the term "transpile". But then again, you're right that on some abstract level, it all is just a translation process from one representation to another.
"A rose by any other name would smell as sweet."
> A compiler is computer software that transforms computer code written in one programming language (the source language) into another programming language (the target language).
Later on it lists some classes of compilers that could be called by more specific names than just "compiler".
"Compilation means taking one type of compiled code and translating it into another type of compiled code."
