Tips
Tips for clean audio
A few settings make the file easier to use.
For speech (podcasts, voice samples), choose mono at 44.1 or 16 kHz.
For music, keep the original channels and sample rate.
Trim silence at the start and end before downloading.
If a file won't open, try another browser — codec support differs.
On a phone, use short clips; long videos need a lot of memory to decode.
Need MP3? Import the WAV into any audio editor and export as MP3.

FAQ
Extract Audio from Video questions
8 questions
How do I extract audio from a video for free?
Drop the video onto this page, trim the part you want, and click Download WAV. It's free, needs no sign-up, and the file is processed in your browser — it's never uploaded.
Link to this answerIs my video uploaded anywhere?
No. The tool uses your browser's built-in audio decoder and creates the WAV locally. Nothing is sent to Kenerate or anyone else.
Link to this answerWhich video formats work?
Most MP4, MOV, M4A and WebM files, plus MKV, MP3 and WAV when your browser supports the audio codec inside. Some codecs, such as AC-3 in certain MKV files, can't be decoded by browsers.
Link to this answerCan I get an MP3 instead of WAV?
The tool exports 16-bit WAV, which every editor accepts. Import it into an audio editor and export as MP3 if you need a smaller file.
Link to this answerHow do I extract audio from a video on iPhone?
Open this page in Safari, tap the drop area, choose the video from Photos or Files, and tap Download WAV. Shorter clips work best on phones because decoding needs memory.
Link to this answerIs there a file size limit?
Files over about 1.5 GB are refused because a browser tab can run out of memory decoding them. Trim long videos first or extract a shorter section.
Link to this answerCan I extract audio from a YouTube video?
Only from a video file you have on your device and the right to use. This tool doesn't download from YouTube or other sites.
Link to this answerHow do I extract audio from a video on Android?
Open this page in Chrome on your Android phone, tap the drop area and pick the video from your gallery or files, trim the part you want, then tap Download WAV. Everything runs in the browser, so nothing is uploaded and no app is needed. Shorter clips work best on phones because decoding uses the phone's memory.

How in-browser audio extraction works
Web browsers include audio decoders for the formats they can play. The Web Audio API's decodeAudioData() method turns an audio or video file's soundtrack into raw samples in memory [1]. The tool trims those samples, optionally mixes them to mono or resamples them, and writes a standard WAV file [2] — all inside your browser tab.
WAV, MP3 and sample rates
What the export options mean:
- WAV — uncompressed PCM audio; larger files, no quality loss [2].
- Mono — one channel; half the size, ideal for speech.
- 44.1 / 48 kHz — standard for music and video.
- 16 kHz — enough for speech, common in phone and speech systems.
Only extract what you're allowed to use
Use the tool on your own recordings, or on videos you have permission to use. It doesn't download from streaming sites.
