How to convert MP4 to MP3
Extract the audio from an MP4 video and save it as an MP3: handy for lectures, podcasts recorded on video, interviews and music you filmed yourself.
- Drop your MP4 file into the box above, or add it from a link.
- MP3 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP3 file.
To do this from your own code, call the FileForge API with "output_format": "mp3".
Good to know
- Choose the bitrate in the settings: 128 kbps is fine for speech, 192–320 kbps for music.
- Use trim start and end to keep only the part you need.
- The audio can only be as good as the soundtrack in the video; a higher bitrate won't add quality that isn't there.
About the formats
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
Questions
Can I convert a YouTube video?

How long does it take?
Usually a few seconds, since only the audio is processed.
Are my files kept?
Your files are uploaded over HTTPS to a private link only you have. Originals and results are deleted automatically after 24 hours, or straight away when you remove them.
