Take the audio, not the picture
Convert MP4 to MP3 online.
Choose a supported video, select an audio track and MP3 bitrate, then create an audio-only result in your browser when the track can be decoded.
It extracts one browser-decodable audio track from a supported video and exports MP3. It does not keep or edit the video picture.

Current inputs include MP3, WAV, M4A, AAC, FLAC, OGG and Opus, plus MP4, MOV and WebM with a decodable audio track. Browser codec support can vary; every file is inspected by its real media structure.
Kept in this browser memoryHow it works
How a video becomes an MP3
AudioCut reads a supported audio track from the video and makes a separate MP3. The video file and its picture are left alone.
- 01
Inspect the selected video for its audio tracks.
- 02
Choose a track that your browser can decode.
- 03
Encode a standalone MP3 at your selected bitrate.
Before you export
A video extension is not the whole story
The download is audio only. Protected, encrypted and browser-unsupported codecs cannot be converted.
Questions people ask
Questions about video-to-MP3 conversion
Does MP4 to MP3 keep the video picture?
No. The converter extracts one audio track that the browser can decode and creates an MP3. The downloaded file does not contain video.
Can I convert MOV or WebM to MP3 too?
Yes, when the selected MOV or WebM file contains an audio track that your browser can decode. A file extension alone does not guarantee that its codec will work.
What happens when a video has more than one audio track?
AudioCut shows an audio-track selector, so you can choose which track to try before making the MP3. If the selected codec is unsupported, AudioCut shows an error instead of producing a result.
Will converting to MP3 lower audio quality?
MP3 is a lossy format and the result may be re-encoded. Choose a higher bitrate when you prefer a larger MP3 with more retained detail.
Why can't AudioCut convert my video?
The video may have no audio track, use an encrypted or unsupported codec, or need more device memory than the browser can provide. Try a different source file or a device that can play the video's audio.
Does converting video to MP3 upload the video?
No. The current converter reads the selected media in this browser and creates the MP3 locally.
