How to convert WebM to WAV online

Open a WebM and export its audio as a WAV file for editing or transcription. The WebM to WAV converter decodes the Opus or Vorbis audio to uncompressed PCM in your browser, without uploading the file.

  1. Step 1

    Choose your WebM
    Pick a file or drop it into the converter above.

  2. Step 2

    Keep WAV
    WAV is selected; choose another audio format if you need one.

  3. Step 3

    Download the WAV
    Save the uncompressed audio when it is ready.

What to expect

Supported inputs
WebM videos and audio-only WebM files, and other readable video or audio files.
What happens
The video track is dropped and the audio is written as uncompressed PCM in a WAV file. WAV is selected first; you can choose another audio format.
Limits
The WebM needs an audio track. WAV files are much larger than WebM audio, roughly 10 MB per minute of stereo sound.

Your files stay on your device

Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.
