Video to MP3 Converter

How to Use the Free Client-Side Video to MP3

Upload a video with audio, pick a bitrate, and extract the soundtrack as an MP3. The conversion uses the Web Audio API running entirely in your browser, so your file is never uploaded to any server.

1. Select a video file with an audio track, such as MP4, WebM, or MOV.
2. Choose your output bitrate — 128kbps, 192kbps, or 320kbps.
3. Click Convert to extract the audio and download it as an MP3 file.

When to Use Video to MP3

Lots of audio worth having is locked inside video containers. Podcast editing starts from recordings that come as video calls; music videos and concert recordings are worth listening to on the move without the video layer; and dialogue and voiceovers need to be pulled out for transcription. This converter extracts the audio track from any browser-playable video format — MP4, WebM, MOV, AVI — and delivers it as an MP3 that plays on anything.

The bitrate control is the knob that shapes the output. At 320kbps you get near-transparent quality for music; at 192kbps you get an excellent balance of quality and size for general use; at 128kbps speech still sounds clear while the file stays small, which makes it ideal for voice work and transcription. Since the entire process runs through the Web Audio API in the browser, it even works offline once the page has loaded.

Video to MP3 Tips and Best Practices

1. Match bitrate to content. Use 128kbps for voice and narration, 192kbps as the everyday balance, and 320kbps for music where fidelity matters.
2. Check that your source actually has an audio track. Silent output usually means the video contained video-only data with no sound to extract.
3. Trim before converting large files. If you need just a portion, cut it with the Video Trimmer first, then convert the smaller segment to MP3.
4. Remember the source limits the result. A compressed source track cannot be improved by a higher output bitrate, so the quality ceiling is whatever the video contains.

Why Client-Side Privacy Matters for extracting audio from personal or proprietary recordings

Audio is deeply personal — voices, conversations, meetings, and recordings that capture people in ways a still image cannot. Extracting the sound from a recording means processing the most identifiable part of it, and doing that on a remote service creates a permanent copy of the audio elsewhere, whether for a podcast, an internal meeting, or a private conversation.

This Video to MP3 converter runs entirely in your browser. The audio is decoded and re-encoded locally with the Web Audio API, and the MP3 is assembled on your device. Your recordings stay private, and the audio you extract exists only where you put it.
