Select a WAV audio file
WAV is uncompressed PCM audio — the format microphones, DAWs, voice recorders and audio interfaces produce. It is perfect for editing but enormous for sharing: one minute of stereo WAV is about 10 MB, so an hour-long recording tops 600 MB. MP3 compresses that by 5–10x with little audible difference at higher bitrates. Choose 320 kbps for music and final masters, 192 kbps as the best size/quality balance, or 128 kbps for voice recordings, podcasts drafts and long meetings where small files matter most.
Drop your WAV file — voice memos, music masters and meeting recordings welcome.
Pick the conversion options that fit — sensible defaults work for most files.
Get your converted file instantly — it plays on every device and platform.
320 kbps for music and anything you care about sonically — most listeners cannot distinguish it from the WAV. 192 kbps is the sweet spot for general use. 128 kbps is ideal for voice recordings, interviews and meetings where file size matters more than fidelity.
A stereo 44.1 kHz WAV runs ~10 MB per minute. At 320 kbps MP3 that becomes ~2.4 MB per minute (4x smaller); at 128 kbps, ~1 MB per minute (10x smaller).
MP3 is lossy, so technically yes — but at 320 kbps the difference from the WAV original is inaudible in normal listening. Keep your WAV masters for editing; use MP3 for sharing and distribution.
No. The conversion runs entirely in your browser using FFmpeg WebAssembly. Sensitive recordings — meetings, voice memos, demos — never leave your device.
Yes. Audio encoding is fast — an hour-long WAV typically converts in well under a minute on a modern laptop. The only limit is your device’s memory for very large files (1 GB+).
Yes. Mono, stereo, 44.1/48/96 kHz and 16/24/32-bit WAV files all convert correctly — the encoder preserves the channel layout and resamples where the MP3 standard requires it.
