MP3 uses lossy compression, so there's some quality trade-off compared to the original WAV, though it's generally not noticeable for speech or casual listening. If you need to preserve every bit of the original, keep a copy of your WAV file alongside the MP3.
WAV files are uncompressed and can be many times larger than an MP3 of the same audio. MP3 is a good choice when you need smaller files for email, messaging apps, or web playback without noticeably sacrificing quality.
