Free video to MP3 converter

Choose a video and save its sound as an MP3. You can also cut just the part you want, add a fade and make a quiet sound louder. It is made on your device, so your video is never uploaded.

Convert a video →No account needed. No watermark.

How it works

  1. Choose your video

    Pick an MP4, MOV, WebM or MKV video from your phone or computer.

  2. Pick the part (if you like)

    The whole sound is chosen for you. Drag the two handles if you only want a part, such as one song from a long video.

  3. Choose the quality

    MP3 is already picked. Good (128 kbps) suits most things, Best (192 kbps) is clearer for music, Small (64 kbps) is enough for voice.

  4. Save

    Tap Save as MP3, listen to the result, then tap Save file.

Tips for video to MP3

Questions

Is this video to MP3 converter free?
Yes. It is free to use, with no watermark and no account.
Is my video uploaded?
No. The sound is read and converted in your browser, on your own device. Nothing is sent to a server.
Which videos work?
MP4, MOV, M4V, WebM and MKV videos, as long as your browser can read them. If a file does not open, you are told.
How long can the video be?
There is no set limit. The sound is read bit by bit, so long videos work. The MP3 is built in memory, so a very long one can be heavy on an old phone. Pick a part if that happens.
What quality is the MP3?
You choose: Small is 64 kbps, Good is 128 kbps and Best is 192 kbps. The size is shown before you save.
Can I convert only a part of the video?
Yes. Drag the two handles on the sound wave, or play the video and tap Start here and End here.
Does it work on a phone?
Yes. It is built for phones, with big buttons. Chrome, Edge and Safari all work.
Can I make a ringtone from a video?
Yes. Open the Ringtone maker, choose the video, pick up to 30 seconds and save it for Android or iPhone.
