Convert audio

Switch audio between MP3, M4A, WAV and OGG using an FFmpeg engine that runs on your device. There is one small one-time engine download, then everything is private and local.

How to convert audio

  1. Drop your audio files.
  2. Choose the output format.
  3. Run, and the engine downloads once, then converts on your device.
  4. Download the converted audio.

Frequently asked questions

Which formats are supported?

You can convert between MP3, M4A, WAV and OGG (Vorbis), all on-device.

Is my audio uploaded?

No. Conversion uses an in-browser FFmpeg engine, so your audio never leaves your device.

Why the one-time download?

The FFmpeg engine (~32 MB) loads once on first use and is then cached for future conversions.
