WAV to MP3
A WAV file is encoded to MP3.
Video tools use FFmpeg (GPL-2.0-or-later).
About this tool
WAV from a recorder or DAW bounce is huge because it is usually uncompressed PCM. This page encodes that recording as MP3 in the browser so you can mail it or drop it in a CMS.
Encoding is lossy. Keep the WAV if you will mix again. Audio converter handles more input types (M4A, OGG, FLAC) and can also emit WAV.
ffmpeg.wasm reads WAV locally and writes MP3. 50 MB. Very long shows at high sample rates can still exhaust memory under that cap.
How to convert WAV to MP3
- Choose a WAV. It stays on your device.
- Convert to MP3.
- Download the MP3 of that recording.
50 MB. Not a CD ripper of commercial discs you do not own. Unusual WAVE chunks may fail the sniff.
FAQ
