Video to MP3 converter

Video to MP3 extracts the audio from any video your browser can play. In practice that covers almost every everyday format:

Browsers generally can't decode the audio in AVI, WMV or MKV files; for those the tool tells you so honestly rather than handing you a broken file. Convert an MKV first with MKV to MP4, and the MP3 will work after that.

A video is a container with the picture and the sound in separate tracks. The tool decodes the audio track with your browser's built-in decoder, ignores the picture, and encodes the sound as MP3. All of it runs on your device: the video isn't uploaded and there's nothing to install.

That also means speed depends on your hardware. On an average laptop, the audio from a ten-minute video is usually ready in a few seconds; a phone takes a little longer. With very long, multi-gigabyte videos, memory can be the limit, because the browser reads the file to decode its audio.

• Audio from a screen recording: turn a recorded online class, webinar or video call into something you can listen to on the go.
• Phone videos: keep or send the sound of a family event, a concert or a speech as a separate file.
• Voice notes from video messages: when someone sent a video but only what they said matters.
• Band practice: a rehearsal recorded on a phone is easier to replay and share as an MP3.
• Transcripts: nearly every transcription tool accepts MP3.

Only work with material you have the right to use: your own recordings, openly licensed content, or content you have permission for. We deliberately don't offer downloading from video sites.

Video soundtracks are almost always compressed already (AAC or Opus), typically at 96–256 kbps. Encoding to MP3 is another compression step, so the result can't beat the source. A practical rule:

• Speech, lectures, calls: 128 kbps. Small files, perfectly clear.
• Music, concert clips: 192 kbps. In everyday listening you won't hear a difference from the source.
• If you'll edit it later: pick 320 kbps, or better still WAV with MP4 to WAV, because a lossless format doesn't degrade with every new save.

If the recording is quiet, run the finished MP3 through the volume booster to bring it up to standard loudness without distortion.

“Contains no audio.” Many screen recordings are made without sound if system audio wasn't switched on. In that case there's genuinely nothing to extract.

“Your browser couldn't decode it.” The audio track uses a less common codec (AC-3 from movies, AMR from old phones). Try Chrome or Edge – they support the most formats.

Slow or stops on a phone. A big video can exhaust a phone's memory. Try on a computer, or first cut out the part you need with the video trimmer.

Only have MP4s? The same engine powers MP4 to MP3; that page accepts MP4 files only, so the file picker stays tidy.

Processing happens in your browser; we don't upload, store or see your file. There's no daily limit and no watermark. The only real ceiling is your device's memory: on a computer, even recordings several hours long usually convert fine, while on a phone, videos of a few tens of minutes are the safe bet.
