How to export properly(?)

Ive been working on a cover and i wanted to export it to my phone via google drive (idk if this is a good option but its the only one i know),, and the picture shows the only way i know how to export it. But the thing is; if i mixdown to WAV, the audio quality is so heavily compressed it sounds honestly terrible. Like someone said; it sounds as if its been recorded and through a shitty mic.

I dont know if this is a rlly noob thing but how do i export it to make the audio quality sound fuller and deeper? Sorry, im very bad at tech stuff and terms but i will try my best to understand 😓
