How to extract audio from a video
- Choose a video or drag it onto the box. MP4, MOV, WebM, MKV and MPEG-TS files work.
- Check the sound details on the right: codec, mono or stereo, and sample rate.
- Pick a preset, or choose the format, quality, channels and sample rate yourself.
- To save only part of the sound, drag the two handles under the preview.
- Press Extract audio and wait for the ring to fill.
- Listen to the result in the player, check the waveform, and download.
Which audio format should you pick?
| Format | Best for | Size for 1 minute |
|---|---|---|
| MP3 | Music, ringtones, podcasts, any player or car stereo | About 1.4 MB at 192 kbps |
| M4A (AAC) | iPhone, iTunes, keeping the original sound unchanged | Same as the video's sound track when copied |
| WAV | Editing in Audacity, Premiere or a DAW | About 11 MB in stereo at 48 kHz |
| OGG (Opus) | Voice, web players, Android, small files | About 0.9 MB at 128 kbps |
Quality, channels and sample rate
For MP3, 192 kbps sounds good for most music and 320 kbps is the highest MP3 allows. Speech is clear at 96 or even 64 kbps. Mono puts both channels into one, which halves the file and suits lectures, interviews and voice notes. Leave the sample rate on Same as video unless an app asks for a specific one. 44.1 kHz is the CD standard and 48 kHz is what most cameras and phones record.
One thing to keep in mind: converting to a higher bitrate cannot add detail that was not in the video. If the video's sound is 128 kbps AAC, saving it as a 320 kbps MP3 makes a bigger file that sounds the same.
Why M4A can be the fastest choice
Most MP4 and MOV videos store their sound as AAC. When you choose M4A with quality set to Same as video, the tool copies that AAC sound into a new file without decoding it. That takes a second or two, and there is no quality loss at all. Some browsers cannot encode AAC, in which case M4A is only available as a copy.
Common uses
- Save a song or speech from a video you recorded.
- Turn a recorded class or meeting into an MP3 you can listen to on the go.
- Pull out the sound of a video to edit or clean it in an audio app.
- Make a ringtone from part of a video, using the trim handles.
Only extract audio from videos you own or have permission to use. Music in films and on streaming sites is usually copyrighted.
Privacy
Your video never leaves your device. The converter code downloads from the jsDelivr CDN the first time you use it, and from then on the work happens inside your browser tab. Nothing is sent to ToolsRiver, and we cannot see your files. When you close the tab, the copies held in memory are gone.
Frequently asked questions
Is it free to extract audio from a video here?
Yes. There is no sign-up and no limit on the number of files.
Can I convert MP4 to MP3?
Yes. Choose MP3 as the format. It is the default setting.
The tool says my video has no sound track. Why?
Some screen recordings and clips saved from social apps contain no audio at all. If you can hear sound when you play the file, tell us on the Contact page and include the file type.
Why does the first MP3 take a little longer?
Browsers do not have a built-in MP3 encoder, so the tool downloads a small one (LAME, compiled for the web) the first time. After that it is ready straight away.
Can I extract audio from a long video?
Yes. Audio is much lighter than video, so even an hour-long recording usually works on a computer. On phones, very long files may take a while.
Does it work on a phone?
Yes, in a recent version of Chrome, Safari or Firefox.
