Audio Extractor

Audio Extractor pulls the sound out of any video file, right in your browser. Upload a video, set a start and end time to trim it, and download the result as a real audio file. Your video is never uploaded to any server — the audio is decoded and cut locally on your device. The download is a WAV file (uncompressed, plays everywhere), because browsers cannot encode true MP3 without a server; any free converter can turn the WAV into MP3 in seconds. Perfect for pulling a song, a voice clip or a sound effect out of a video.
How to use Audio Extractor
- Upload any video file (MP4, WebM, MOV and more — the browser reads the audio track).
- Wait for the duration to appear, then set a start and end time if you only want part of the audio.
- Press “Extract Audio” — the audio is decoded and trimmed in your browser.
- Download the WAV file. Convert it to MP3 with any free converter if you need MP3.
Worked example
Example: a 2-minute video of a speech. Upload it, set start 0:10 and end 1:30, press Extract Audio — you get a clean 80-second WAV of just the speech, ready to use in your own edit or as a ringtone.
Tips for better results
- Trim before extracting if you only need a short clip — the file stays small.
- WAV is uncompressed, so it is bigger than MP3 but keeps full quality.
- Long videos take a little longer to decode — the browser is doing real work, keep the tab open.
- If a video has no audio track, the tool will tell you honestly instead of giving you silence.
Frequently asked questions about Audio Extractor
Is the audio extractor free?
Yes, completely free — everything runs in your browser, no API key needed.
Is my video uploaded anywhere?
No. Your video never leaves your device. Decoding, trimming and the download all happen locally in your browser.
What audio format do I get?
A WAV file (uncompressed, full quality). Browsers cannot encode true MP3 without a server, so this tool gives you WAV — any free converter can turn it into MP3 in seconds.
Can I extract only part of the audio?
Yes — set a start and end time and only that part is extracted. Leave them at 0 and the full duration to extract everything.
Which video formats work?
Any video your browser can play: MP4, WebM, MOV and more. If the browser cannot read the file, it will say so.
What if my video has no audio?
The tool checks and tells you honestly that no audio track was found, instead of downloading an empty file.
Can I extract audio from a 3-hour video?
Yes — there is no site-imposed size limit. Decoding a very long video uses more memory and takes longer, but it works.
