Extract Audio from Video
Pull the soundtrack out of any video as lossless WAV — right in your browser
Output is lossless 16-bit WAV at the original sample rate — perfect for editing, transcription or re-encoding.
Track handling specifics
- Stream copy — when the source codec matches your target, packets move unchanged: no generation loss, near-instant.
- First-track rule — multi-audio files take track #1 by default; available tracks list with languages when present.
- Normalization option — optional loudness fix to −16 LUFS for podcast-style consistency.
Extraction that skips re-encoding when it can
Copy-mode pulls the existing audio track bit-perfect in seconds; re-encoding starts only when you pick MP3/AAC targets or change bitrate.
Lossless 16-bit WAV output
The audio track is decoded to an uncompressed 16-bit PCM WAV, so every note survives at its original sample rate — a clean source for editors, podcasters and musicians.
Mono downmix halves the file
Choose mono and the two stereo channels are averaged into one, cutting the WAV roughly in half — useful when voice matters and the file size does not.
Size estimate before you export
The page shows an approximate output size right after you drop a file, before extraction starts, so you know what you are getting. Files up to 500 MB and 20 minutes long are accepted, and plain audio files work too.
How it works
- 1
Drop in a video — it loads locally and is never uploaded.
- 2
Choose stereo or mono output.
- 3
Hit Extract, listen to the result right on the page, then download the WAV.
Frequently asked questions
Is my video uploaded to extract audio?⌄
No. The audio track is decoded with your browser's built-in Web Audio engine, so the file never leaves your device. There are no queues and no export time limits.
Why WAV and not MP3?⌄
WAV is lossless — the extracted audio is bit-perfect at the original sample rate, which is exactly what you want for editing, transcription or feeding another encoder. Converting straight to MP3 would lose quality a second time. Any editor or online converter can turn the WAV into MP3 if you need one.
Why is the WAV file so big, and how can I make it smaller?⌄
Uncompressed CD-quality stereo is about 10 MB per minute — that is the cost of lossless audio. Choose the mono downmix to halve it (fine for voice recordings, podcasts and lectures), or run the WAV through any MP3/AAC converter afterwards.
Why is my extracted file bigger than expected?⌄
Copy mode preserves the original audio exactly — including high-bitrate PCM from camera files. Choose MP3 192k if size matters more than fidelity.

What Does Extract Audio from Video Mean?
Extracting audio from a video means pulling the soundtrack out and saving it as a standalone audio file, so you can listen to it, edit it or reuse it without the picture. This tool does exactly that in your browser: you drop in an MP4, WebM or MOV video, and it decodes the audio track and saves it as a lossless 16-bit WAV, with an optional mono downmix that halves the file size. It is ideal for podcasters, students, musicians and anyone who wants the sound without the video. There is no file size cap and no waiting on a server: the conversion is done locally, so even long recordings finish as fast as your device allows.
What this tool can do
- 🎵 Open MP4, WebM and MOV videos and extract their audio track
- 💿 Save the result as a lossless 16-bit WAV file
- ⚖️ Optional mono downmix halves the file size
- ⏱️ No export time limits — long videos are fine
- 🔒 Files stay on your device; nothing is uploaded
- 🆓 Free to use, with no watermark and no account
When you would use it
- You want to listen to a lecture or interview as audio on the go
- You sample music or sound effects from a video for your own edit
- You need an audio backup of a video recording
- You want to make a ringtone from a video sound
Processing happens entirely in your browser: the video audio is decoded on your device and written to WAV locally — nothing is ever uploaded, so there are no privacy concerns and no duration walls. One thing to know: WAV is an uncompressed format, so files are large — that is the price of lossless quality — and the source video must be in a format your browser can decode.
