Extract Audio from Video

Pull the soundtrack out of any video as an MP3. Some detail is discarded to fit the target format; how much depends on the format and your settings.

How to use it

  1. 1

    Add your files

    Extract Audio from Video works with MP4, MOV, MKV, WebM, AVI, FLV, MPEG, 3GP, TS, OGV and WMV. Drop them in, browse for them, or paste from your clipboard.

  2. 2

    Choose your options

    Tune bitrate, sample rate and channels and start and end times — or leave the defaults, which are sensible.

  3. 3

    Run it and download

    Press the button and save the result. Everything happens on your device, and nothing is uploaded.

Privacy, in plain words

Is it safe? Your video file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your video file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Video is the format where the thing being converted is usually a recording of people, and often of people who did not expect a third party to have a copy. It matters more than it sounds, because of what video files usually are:

Family videos

children, addresses, the inside of your house

Medical or therapy consultations

clinical recordings under strict handling rules

Unreleased footage

material under embargo or still being edited

Recorded meetings and calls

everything said, by everyone in the room

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

How Extract Audio from Video works

Pull the soundtrack out of any video as an MP3. Everything happens inside this page: the file is read from your device into memory, processed there, and handed back as a download. It is never sent anywhere, and closing the tab discards it.

What it accepts
MP4, MOV, MKV, WebM, AVI, FLV, MPEG, 3GP and 3 more. Files are identified by their contents rather than their name, so a mislabelled file is still handled correctly.
What you get back
A MP3 file, downloaded straight to your device.
What happens to the data
The result is re-encoded, so some detail is discarded permanently. Starting from the original rather than from an already-processed file keeps that loss to one pass.
Size limit
Up to 512 MB per file. Because the work happens on your own machine, available memory is the real constraint — a laptop handles far more than a phone.

The settings, and what each one changes

Extract Audio from Video exposes 6 settings. The defaults are chosen to suit the common case, so changing nothing is a reasonable way to start.

Bitrate
Choose between 320 kbps, 256 kbps, 192 kbps, 128 kbps and others.
Sample rate
Choose between Keep original, 48 kHz, 44.1 kHz, 22.05 kHz and others.
Channels
Choose between Keep original, Stereo, Mono.
Normalise loudness
Applies EBU R128 loudness normalisation to -16 LUFS.
Start at
Leave both empty to keep the whole file. Accepts seconds or HH:MM:SS.
End at
Free text, used exactly as you type it.
Measured, not estimated

What this tool actually does to a file

Pulling the soundtrack out of a clip as an MP3 and discarding the picture.

On every sample measured, the result came out smaller — 1.4× smaller at worst and 20× smaller at best.

Each row is one document, chosen because this tool behaves differently depending on what is inside the file.

A hard clipThe other end — pink noise, or dense video grain. Close to incompressible by design, and the worst case for every codec.1000 KB49.1 KB−95%

Produced by this site's own converter. The same code that runs in your browser, at the same default settings, so these are the bytes you would download.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size. Measured 2026-10-01. The method, and the command that regenerates every figure on this page, are on the how it works page.

Extract Audio from Video — questions

How does Extract Audio from Video work?

Pull the soundtrack out of any video as an MP3. Add your files above, adjust anything you want to change, and press the button. The result downloads straight to your device.

Is Extract Audio from Video safe — are my files uploaded to a server?

No, nothing is uploaded. On most online tools, pressing the button copies your file across the internet onto a computer owned by that website, where it is processed and then sent back. That copy is what "upload" means. This tool does not do it: your file is read and processed by the browser you are using right now, stays on this device the whole time, and is discarded when you close the tab. Turn off your Wi-Fi after the page loads and it still works, which is the quickest way to confirm it.

Can I use this on confidential or personal documents?

Yes — that is the case it was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder: there is no transfer, no copy on anybody else's hardware, no retention period and no staff with access. Nothing about the file is logged either — not its name, not its size, not its contents.

Do I need an account?

No. Every tool on FileTools360 works without signing up, and there is no watermark on the output.

What is the file size limit?

512 MB per file. Since everything runs locally, your device's available memory is the real constraint.
