Video to audio
Extract audio from a video and keep the MP3
AudioCut reads a supported video track and creates audio only. The source video stays unchanged.
Choose a video, pick a track if there is more than one, select a bitrate and create an MP3.

Current limitsBrowser codec support and device memory still matter. AudioCut exports MP3.
How to do it
Convert a video in three steps
Follow these steps, then listen before downloading.
- 01
Choose the video
Use an MP4, MOV or WebM file that contains audio. The browser still needs to recognize the actual codec inside the file.
- 02
Pick the audio you want
When the video exposes multiple audio tracks, AudioCut lets you select one. Check the language or track label before you continue; an unsupported codec will show an error instead of a result.
- 03
Select a bitrate and listen
A higher MP3 bitrate makes a larger file. Create the result, preview it and confirm the audio track before downloading.
Quick check
What the converter can return
The container is only part of compatibility.
| Situation | What AudioCut does | What to keep in mind |
|---|---|---|
| The video has one audio track the browser can decode | Uses that track to create MP3 | The exported file contains sound only, not the video picture. |
| The video has several audio tracks | Shows an audio-track selector | Choose a track before conversion; an unsupported codec shows an error instead of a result. |
| The browser cannot decode the track | Stops instead of creating a misleading result | Try a compatible source file or a browser/device that can play the track's audio. |
| You need a video with new audio timing | Does not edit the video | Current AudioCut tools export audio MP3 only. |
Keep in mind
Output limits
- MP3 is a lossy audio format, and conversion may re-encode the original audio track.
- Protected, encrypted or unsupported codecs cannot be converted by the current browser-based tool.
- Only process media that you own or have permission to use.
Common questions
Short answers for this task.
Can I extract audio from a MOV or WebM file?
Yes, when its audio track is decodable in your browser. AudioCut accepts the container but cannot promise that every codec inside it will work.
Does converting MP4 to MP3 upload the video?
No. The current converter reads the file in this browser and creates the MP3 locally.
Can I keep the original video after converting?
Yes. The original video is not changed. AudioCut creates a separate MP3 result for you to preview and download.
