What people use it for

  • Turn an MP4 lecture or webinar recording into an MP3 you can listen to on the go.
  • Extract the audio from a Zoom or Teams recording before sending it to a transcription service.
  • Pull a clean WAV soundtrack out of a video clip for editing in Audacity or a DAW.
  • Save the audio from an interview shot on a phone (MOV) as MP3 for your notes.
  • Rip the music bed from a screen recording so you can reuse it in another edit.
  • Convert a MKV concert recording into FLAC for lossless listening.
  • Batch-extract audio from a folder of video podcasts and publish them as an audio feed.

This free video to audio converter extracts the sound track from MP4, MOV, MKV, WebM, AVI, and other video files and saves it as MP3, WAV, FLAC, M4A, OGG, or Opus — without uploading anything. It runs on ffmpeg.wasm, the same FFmpeg engine desktop video tools use, compiled to WebAssembly, so an MP4 to MP3, MOV to MP3, MKV to MP3, or WebM to WAV extraction happens entirely on your own computer.

People usually reach for this when they want to convert video to audio for listening or transcription: a recorded lecture, a Zoom or Teams meeting, a webinar, a video podcast, or a phone interview. You choose the bitrate, sample rate, and channel count, and you can apply EBU R128 loudness normalization so a set of recordings all end up at the same perceived volume. Mono at 32 kHz keeps speech files tiny; 192–320 kbps stereo keeps music sounding right.

Because the video never leaves your browser, there is no upload wait, no queue, no ads, no e-mail, no watermark, and no server holding a copy of confidential footage — which matters for client meetings, medical or legal recordings, and unreleased material. Free users process one video at a time, up to 100 MB, three times a day. Pro members extract audio from unlimited videos, queue up to 50 at once, and download the whole batch as a ZIP.

How it works

    Drop your video

    Drag in an MP4, MOV, MKV, WebM, or AVI file, or click to browse. It stays on your device.

    Choose MP3, WAV, FLAC, M4A, OGG, or Opus, then set bitrate, sample rate, channels, and optional loudness normalization.

    ffmpeg.wasm decodes the video locally and writes just the audio. Save it, or grab a whole batch as a ZIP.

Frequently asked questions

No. The extraction runs entirely in your browser with an in-browser build of FFmpeg (ffmpeg.wasm). Your video never leaves your device — no server ever sees it.
