Home › Free tools › MP4 to MP3
Choose a video and get its audio as an MP3, ready to play, send or transcribe. This online converter works inside your browser, so the video isn't uploaded anywhere.
Your file never leaves your device: it's converted right in your browser. Free, no account needed.
“Transcribe to text” opens TraScrivo with the file already loaded: free for files up to 30 minutes, even without an account. To transcribe, the audio is processed online and then deleted.
The tool takes the video's first audio track and encodes it as MP3; the images are discarded. The original video stays on your device, untouched.
If the video has multichannel audio (5.1, for example), the MP3 is saved in stereo, so it plays properly on any player.
It depends on the length of the video and on your device: the bar shows the progress. A computer is faster than a phone, and there's no upload or queue to wait for.
The first time, your browser downloads the converter (about 30 MB); after that, it starts right away.
Need the text of a lecture, an interview or a meeting? Press Transcribe to text: TraScrivo opens with the MP3 already loaded and transcribes it with timestamps. See also our guide to turning video into text.
Yes, with no account, no watermark and no limit on the number of files.
Yes. The tool accepts the most common video formats, including videos recorded on an iPhone (MOV).

On a computer you can use videos up to 2 GB. iPhone and iPad have less memory: about 3 hours of audio at the recommended quality.
No. Everything happens in your browser and the file never leaves your device.
