ConvertWarp

Audio converter

WAV, MP3, M4A, OGG, and FLAC can become an MP3 or a WAV. The same format is kept unchanged.

Audio conversion uses FFmpeg (GPL-2.0-or-later).

About this tool

Audio converter turns WAV, MP3, M4A, OGG, or FLAC into MP3 or WAV in the browser. If you pick the same format you already have, the file is left unchanged instead of being transcoded for no reason.

This is a utility encoder, not a mastering suite. Sample-rate and loudness are not a mixing desk. WAV to MP3 remains the shortcut URL for the most common recorder export.

ffmpeg.wasm transcodes locally unless in and out match. 50 MB. Unsupported codecs fail in the tab. No upload of the recording.

How to convert audio

  1. Choose WAV, MP3, M4A, OGG, or FLAC. It stays on your device.
  2. Pick MP3 or WAV as the output.
  3. Convert. Same-to-same keeps the original bytes.
  4. Download the MP3 or WAV you picked.

50 MB. Not a Spotify downloader. Multi-track DAW sessions are not stems here.

FAQ

Does choosing MP3 or WAV out upload the track?
No. Conversion is local.
Why keep same-format files?
Re-encoding MP3 to MP3 only hurts. Unchanged is the honest result.
FLAC to WAV quality?
That direction is lossless if ffmpeg decodes the FLAC. MP3 out is not.
Voice memos from iPhone?
M4A often works. If the sniff fails, the file is not a supported codec — we will not send it to a server to try harder.
Video files?
Use MP4 to MP3 or Extract audio. This page is audio containers.
