WAV is an uncompressed, lossless format that stores raw audio at full quality. Files are large, but the audio is pristine, which is why it is the standard for editing and mastering. MP3 is the most universally compatible audio format. It uses lossy compression to make small files that play on virtually any device, app or website. MP3 compresses the audio into a much smaller file that’s easy to share and plays everywhere, with only a small and usually inaudible loss of quality.
