How to: WAV to MP3
- Select WAV files.
- Pick a bitrate.
- Download the MP3.
WAV is uncompressed and large – about 10 MB per minute in CD quality. MP3 at 192 kbps is roughly 7× smaller and sounds nearly identical for most listeners.
Common uses
- Shrink studio or recorder files for sharing.
- Save space on your phone or music player.
- Email or upload recordings faster.
Tips for best results
- Use 256–320 kbps for music masters; 128 kbps for speech.
- Keep the WAV as your master copy.
Choosing a bitrate
128 kbps is fine for speech and casual listening, 192 kbps is a good all-round choice for music, and 320 kbps is the highest MP3 quality for archiving and DJ use. A 5-minute WAV of about 50 MB becomes about 7 MB at 192 kbps.
Keep a master copy
MP3 is lossy: each re-encode loses detail. Keep the original WAV for editing and create MP3s only for sharing and playback.
