Pull the audio track out of any video file and save it as an MP3 — perfect for extracting music, interview recordings, lecture audio, or podcast recordings from video files. Choose your output bitrate (64–320 kbps) to balance quality and file size. Everything runs in your browser via FFmpeg WebAssembly — your video files never leave your device.

Upload your video file
Drop an MP4, MOV, MKV, or WebM file. The audio track will be extracted regardless of the video codec — HEVC, H.264, VP9, and AV1 are all supported as video containers.
Choose bitrate
192 kbps (our default) is excellent quality for music and speech. Use 128 kbps for podcasts and interviews. Use 256–320 kbps for high-fidelity music archiving. Lower bitrates (64–96 kbps) produce the smallest files for voice-only content.
Click Convert
FFmpeg extracts the audio stream and re-encodes it as MP3 using the LAME encoder. Progress is shown in real time. Large video files may take a minute or two.
Download your MP3
The output MP3 plays in every audio player, podcasting app, and music software. Import into Audacity, GarageBand, or Adobe Audition for further editing.
Audio extraction requires decoding the audio stream and re-encoding it as MP3. The video frames are skipped (the -vn flag in FFmpeg drops video), but audio decoding and LAME MP3 encoding still require CPU time proportional to the audio duration — roughly 10–30 seconds per hour of audio in the browser.
Only the first audio track is extracted. For videos with multiple language tracks or commentary tracks, the first track (usually the primary language) is used. To extract a specific track, you'd need a desktop tool with track selection controls.
The audio in video files is usually already compressed (AAC, AC-3, Opus). Re-encoding to MP3 introduces a small additional quality loss. At 192 kbps MP3, this is imperceptible for speech and near-transparent for music. If you need lossless audio, use a WAV converter instead.
Yes. Zoom recordings are typically MP4, and Teams recordings are MP4 or WebM — both supported. Just upload the recording file and extract the MP3. This is useful for creating podcast episodes, transcripts, or audio archives from recorded meetings.
Extraction means pulling the audio from a video container (MP4 → MP3). Conversion means changing between audio formats (WAV → MP3). Both use FFmpeg. Extraction skips video processing, so it's faster than full video conversion for the same file.
