Extract Audio from Video
Drop a video and download its audio as MP3 or WAV. Processing stays on your device.
Save as
First run downloads a small media engine from a CDN into your browser (cached afterward). Large videos may be slow or run out of memory on phones — try a shorter file if needed.
How to extract audio from video in your browser
Pull the soundtrack from MP4, WebM, MOV, and similar videos as MP3 or WAV. ffmpeg.wasm runs locally after loading from a CDN — the video is not uploaded to our servers.
How to use it
- Drop a video file.
- Choose MP3 or WAV.
- Download the extracted soundtrack when processing finishes.
When it helps
Ideal for saving a lecture soundtrack, pulling music from a screen recording, or getting audio without a desktop video editor.
FAQ
- Which video formats work?
- Common containers such as MP4, WebM, MOV, and MKV usually work when the audio codec is supported by the browser engine. Exotic codecs may fail.
- What if there is no soundtrack?
- Extraction will fail with an error. Silent or video-only files cannot produce audio.
- Are large videos OK?
- They can be slow and memory-heavy in the browser. Prefer shorter files on phones.
- Is my video uploaded?
- No. Processing stays in your tab after the media engine loads from a CDN.
- Can I trim the video first?
- Yes — use Trim Video to keep only the section you need, then extract audio from that shorter file if you want.
