Convert WAV to MP3 Online — Free
WAV is uncompressed — a 3-minute song is ~30 MB. MP3 brings that down to ~3 MB with no audible difference at decent bitrates. ReFile converts WAV to MP3 at any bitrate, from podcast-tier (64kbps mono) to audiophile-tier (320kbps).

Frequently asked
- What bitrate should I use?
- 320kbps for music you'll keep, 192kbps for casual listening, 128kbps for voice with some quality, 64kbps mono for pure speech (podcasts, audiobooks).
- Can ReFile keep it lossless?
- MP3 is always lossy. For lossless, ask for 'WAV to FLAC' instead — same audio, ~half the size, still lossless.
