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).

  • No signup to try
  • Sandboxed processing
  • Files deleted in 24 h

What this does

  • Default: 192kbps stereo MP3 — good balance for music
  • Voice / podcast — 'MP3 at 64kbps mono'
  • Audiophile — 'MP3 at 320kbps' (the maximum)

How it works

  1. 1

    Upload your WAV

    Drop it above, or click to pick from your device. We validate the format immediately — no spinning on a file we can't process.

  2. 2

    Run the conversion

    The recipe runs in an isolated cloud sandbox — same as every other ReFile job. No AI guessing involved; it's a hand-written command that does one thing.

  3. 3

    Download the MP3

    Result lands in seconds. Files auto-delete from our servers after 24 hours; signed download URLs expire in the same window.

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.
