What you get when you extract audio
An MP3 contains only sound. It is a compressed audio format that plays on practically every phone, car stereo, computer and music app, and the files are much smaller than the video they come from.
This is handy for lectures, interviews, podcasts recorded on video, concert clips and voice notes. The original video is left untouched, so you keep both versions.
How to convert MP4 to MP3
- Drop your MP4 video on the page.
- If you only want part of the audio, set the start and end in the Trim tab.
- Open the Audio tab and adjust the volume if you wish.
- Press Download MP3 and save the file.
Choose only what you need
The Audio tab shows the waveform of your video with your selection highlighted. Set a start and an end in the Trim tab to keep only the song, the answer or the speech you want instead of the full recording, and change the volume in the Audio tab if the original is too quiet.
Only convert audio that you own or have permission to use. Music, films and shows are usually protected by copyright, and the rules depend on your country.
Questions
Can I convert other formats to MP3?
Yes. WebM, MOV, MKV and AVI videos open in the same way, and you can extract their sound as MP3.
Does the video get uploaded?
No. The audio is extracted in your browser and never leaves your device.
Can I extract only a part of the audio?
Yes. Set the start and end in the Trim tab before you export, and the waveform in the Audio tab shows what you keep.
