Video to MP3 Converter

Convert a video to MP3 from MP4, MOV, WebM or MKV and keep only the audio, at up to 320 kbps. It runs in your browser, so nothing is uploaded.

Added Oct 20, 2026

The Video to MP3 Converter handles video to mp3 in your browser. It takes the common video formats (MP4, MOV, WebM and MKV), drops the picture, and gives you the soundtrack as an MP3 file. Everything runs on your own device: the video is never uploaded, nothing is stored, and it spends no credits.

What can I turn into an MP3?

Whatever video you have on hand, in most cases:

  • MOV clips from an iPhone or a Mac screen recording.
  • MP4 files from Android phones, cameras, Zoom or most editors.
  • WebM recordings from browser tools and screen recorders.
  • MKV files from desktop recorders and archives.

It also accepts audio files your browser can decode, so the same page turns an M4A or a WAV into an MP3.

How do I extract audio from a video?

  1. Drop the video, or pick it from your device.
  2. Leave MP3 selected and choose 128, 192 or 320 kbps.
  3. Convert and download the MP3.

The audio is encoded with LAME, the MP3 encoder, running right in the browser. A progress bar shows how far along it is, and Stop cancels the job. One video converts at a time.

When does a video to MP3 conversion make sense?

When the sound is the part that matters. A recorded meeting becomes something you can replay in the car. A webinar turns into a podcast-style episode. A song you recorded at rehearsal goes straight into a music app. A video message from family becomes an audio keepsake that plays on any phone. Voice-over takes from a shoot can be handed to an editor without the heavy footage.

MP3 is the safe choice for all of that, since car stereos, phones, speakers and podcast apps all play it. For editing work, WAV keeps the audio uncompressed; for Apple apps, M4A (AAC) is also there. The audio in a video is usually compressed already, so a high bitrate keeps what is there but can’t restore detail that was lost.

If you need the video itself in another container, use the Video Converter. For a straight MP4 to MP3 page, there’s one too.

FAQ

Is the video uploaded?

No. The video to mp3 conversion runs in your browser, and nothing is stored.

Can I keep only part of the video?

It converts the whole soundtrack. Trim the MP3 afterwards in any audio app.

What does it cost?

It comes with the Nexin library: Nexin Lite or Nexin Pro opens it, and it spends no credits.
