How to convert WebM to MP3 online

Open a WebM, such as a browser screen recording or a downloaded clip, and export its audio as an MP3. The WebM to MP3 converter decodes the Opus or Vorbis audio and encodes MP3 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 MP3
    MP3 is selected; choose another audio format if you need one.

  3. Step 3

    Download the MP3
    Save the sound when the conversion finishes.

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 encoded as MP3. MP3 is selected first; you can choose another audio format.
Limits
The WebM needs an audio track. Encoding time depends on the file's length and your device.

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.

“This was exactly what I needed for uploading a YT video. I’m so grateful for how easy it was. Saved me so much time and energy.”

Questions

Yes. WebM files that hold only sound convert the same way.

Many phones, car stereos, and music apps don't play WebM. MP3 plays almost everywhere.
