WAV. WAV stores raw PCM samples with no compression at all. What you save is exactly what the editor sees, which is why studios and editors use it.

MP3. MP3 throws away sound the ear is unlikely to notice, using a psychoacoustic model, so a song shrinks to roughly a tenth of its CD size.

What happens to quality

WAV is lossless and MP3 is lossy, so the conversion discards some detail. At the default bitrate most listeners can’t hear the difference, and the file becomes far smaller. Hear the difference between lossless and MP3 yourself.
