How to convert MP4 to MP3
- Add your video. Drag an MP4 file onto the box above or tap it to choose a video from your phone or computer. MOV, M4V, WebM and MKV also work.
- Choose the audio quality. 192 kbps is recommended; pick 128 kbps for smaller files or 320 kbps for the best quality.
- Press Convert to MP3. On your first visit the converter downloads once (about 31 MB). A progress bar then shows the conversion as it runs, and you can cancel at any time.
- Listen and download. Play the MP3 right on the page to check it, then download it. The file keeps your video's name.

Why use Fileora's MP4 to MP3 converter
Video files are big. Uploading a 300 MB recording to an online converter can take longer than the conversion itself, and it means handing a copy of your video to a server you know nothing about. Fileora converts the video on your own device instead. Your recording of a family event, a lecture or a meeting stays private, and there's no upload queue, no file size cap and no daily limit.
The converter is completely free, doesn't add a watermark or jingle to your audio, and doesn't ask for an account. It works in current versions of Chrome, Edge, Firefox and Safari on computers and phones.
Common reasons to extract audio from a video include keeping the soundtrack of a recorded talk to listen to on the go, turning a voice recording made with your phone's camera into an audio file, or pulling a clip of music you created out of your own video project. If you want to share the audio alongside documents, you can merge PDFs or compress images with the same privacy.
Tips for the best result
MP3 conversion can't add quality that wasn't in the original, so matching the bitrate to the source is the smartest choice: phone videos usually carry 128–256 kbps audio, so 192 kbps preserves nearly all of it. Very long videos need a lot of memory while converting. If a large file fails on your phone, try it on a computer, or close other browser tabs first. And because everything runs locally, the conversion speed depends on your device: a modern laptop converts several minutes of video in a few seconds.
