How to extract audio from a video as MP3
November 12, 2026 3 min read
Short answer
To extract audio from a video, open it in an audio extraction tool or video editor and save just the sound as an MP3. You can do this in your browser too, without installing anything or uploading the video. Only use it for your own videos or content you have the rights to use.
Wanting the sound of a talk, a lecture, a meeting recording or a song you played yourself as a separate file is very common. MP3 plays on almost every device, so it's the most practical format.

The Extract audio tool on mp4indir processes the video on your device and gives you its sound as an MP3. The video is not uploaded to a server.
- 1Open the Extract audio tool.
- 2Drag and drop the video or choose it from your device. You can pick more than one.
- 3If you only want part of the audio, set the start and end; leave it as is for the whole thing.
- 4Choose a quality and press Extract as MP3. Download the file when it's done.
Which quality should I pick?
MP3 quality depends on how much data is used per second (the bitrate). Higher quality means clearer sound but a bigger file.
For speech, lectures or meetings, standard or small is plenty. For music or recordings where sound matters, use high. Keep in mind that an MP3 can't be better than the original sound; if the video's audio is already poor, the high setting only makes the file bigger.
On a phone and on a computer
On a phone: open the tool in your browser and pick the video from your gallery. Short videos finish quickly; very long ones are more comfortable on a computer. Some phones' gallery or editing apps also have an option to separate audio, so it's worth checking your own phone's menus.
On a computer: the same tool works in your browser. If you regularly work with lots of files, free desktop programs like VLC or Audacity can also export the audio.
Copyright: what can you extract?
This is for videos you filmed yourself, recordings you own, or content you have clear permission to use. Taking someone else's music or videos from platforms and turning them into MP3s can break copyright law and most platforms' rules.
mp4indir does not download videos from any platform; it only works with files that are already on your device.
Frequently asked questions
- Does extracting audio lower the quality?
- MP3 is a compressed format, so there is a small loss, but at high or standard quality it is hard to hear.
- Can I take only part of the audio?
- Yes. Set a start and end point to save just that section as an MP3.
- Can I extract audio from an iPhone video?
- Yes. iPhone videos work the same way; open the tool in Safari and pick the video from Photos.
- Can I turn a song from YouTube into an MP3?
- No, this tool isn't for that. Content on platforms belongs to its owners, and downloading and converting it can infringe copyright. Use legal streaming or buy the music instead.
