Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Extract the audio track from any MP4 or MOV video and save it as an MP3 — the extraction and encoding run in your browser, so nothing is uploaded and even hour-long recordings convert without limits. Drop a video, pick a bitrate, download just the sound.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
What the MP3 can and cannot contain
Extraction re-encodes the sound that is already in the video — it cannot add fidelity that was never recorded. For talks and interviews filmed on a phone, 96–128 kbps captures everything there is; for concert or music footage, go 192 kbps or higher. To convert audio you already have as files, the audio tool handles MP3, M4A, WAV, FLAC, OGG and more directly.
Typical uses
| Task | Setting |
|---|---|
| Lecture or podcast from a recording | 96–128 kbps |
| Song from a music video | 192–256 kbps |
| Voice notes for transcription | 96 kbps |
| Fit a size cap | Target size — type the cap |
Frequently asked questions
Does the video quality matter for the MP3?
No — the audio track is independent of the picture. A 4K and a 480p copy of the same video produce the identical MP3, because only the sound is re-encoded.
What bitrate does the MP3 use?
Whatever you pick — 192 kbps by default, which sounds identical to the original for music. Switch to Target size mode to aim at a specific file size instead.
Can I extract audio from many videos at once?
Yes — drop any number of MP4 or MOV files and each produces its own MP3, downloadable individually or as one ZIP. Long recordings work too; there is no length limit.
Is it private?
Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
