Extract Audio from Video
Guide & FAQGuide: Extract Audio from Video
How to extract audio from a video
Drop a video on the page or click to choose it. The tool reads the sound track and shows its length and sample rate. Pick MP3, M4A or WAV, set the quality, and press Extract audio. When it finishes, play the result and press Download.
Choosing a format and quality
- MP3 at 128 kbps is small and works on every device; use 192 or 256 kbps for music.
- M4A (AAC) sounds better than MP3 at the same bitrate.
- WAV keeps every detail but is about ten times larger.
Taking just a part
Enter a start and end time to extract only a section, for example one song from a concert recording or one quote from an interview. Use Listen to check before extracting.
Notes
The conversion runs in your browser on your own device, so there is no upload wait and no account. Very long videos need more memory; if the browser runs out, try a shorter clip. Only extract audio from videos you have the right to use.
FAQ
Which video formats can I use?
Any video your browser can play: MP4 and MOV with AAC audio, WebM with Opus or Vorbis, and often 3GP and MKV. If a file cannot be read, the tool tells you. Converting it to MP4 first usually fixes it.
Is there a file size or length limit?
The tool sets no limit. The practical limit is your device memory, because the sound is decoded in the browser. A laptop handles videos of an hour or more; a phone is better with shorter clips.
Does the video get uploaded anywhere?
No. The tool makes no upload requests: the file is read and converted by your browser on your device.
Which format should I choose?
MP3 plays everywhere. M4A (AAC) gives better quality at the same size and works on Apple devices and most players. WAV is uncompressed, large, and best when you want to edit the sound further.
Can I take only a part of the sound?
Yes. Type a start and end time before extracting. Use the Listen button to check the part first.
Why is the result mono?
Some videos only have a mono sound track. You can also tick the Mono option yourself to halve the file size.
