People believe some languages are "higher level" than others and call a tool that translates programs written in A to programs written in B a compiler if A is clearly higher level than B and a transpiler if B is of a level higher than or roughly equal to A.

You can certainly think this distinction doesn't merit using a different word, but you shouldn't think that people who use the word "transpile" use it as a synonym for "compiler".
