To convert video to MP3, drop the video into the MobileStudio Video to MP3 tool, choose a quality (128, 192, or 320 kbps), and download the MP3. It works on any phone or computer, lets you keep just one part of the soundtrack, and runs in your browser so the video is never uploaded. On a computer, VLC and Audacity can do it too.
The short answer
| You're on | Easiest free way | Output |

How do I convert a video to MP3 for free?
- Open Video to MP3.
- Drop in the video (MP4, MOV, or WebM).
- Drag the handles if you only want part of the audio.
- Choose MP3 and a quality: 128 kbps for speech, 192 kbps for most music, 320 kbps for the best MP3 quality.
- Click Extract MP3 and download it.
You can play the result before downloading. A one-minute clip at 192 kbps comes out around 1.4 MB.
Should I pick MP3 or WAV?
Pick MP3 to share, listen, or upload, because it's about a tenth of the size. Pick WAV if you'll edit the audio in GarageBand, Audacity, or a video editor, since WAV keeps every detail. The Library of Congress describes MP3 as a perceptual codec that drops sounds you're least likely to hear, while WAVE usually holds uncompressed audio. More in MP3 vs WAV.
How do I convert video to MP3 on a computer?
- Mac: QuickTime Player's File > Export As > Audio Only saves an M4A, as Apple's QuickTime guide shows. To get MP3, open that file in the Music app and use File > Convert > Create MP3 Version. Full steps: convert MP4 to MP3 on Mac.
- Windows: In VLC, choose Media > Convert / Save, add the video, and pick the Audio - MP3 profile. Full steps: convert MP4 to MP3 on Windows.
How do I convert video to MP3 on a phone?
Open the Video to MP3 tool in Safari on iPhone or Chrome on Android and follow the same steps. On iPhone, the Shortcuts app can also extract audio, but it saves M4A rather than MP3. See extract audio from video on iPhone.
Which MP3 quality should I choose?
| Content | Bitrate | About this much per minute |
|---|---|---|
| Voice notes, lectures, podcasts | 128 kbps | 1 MB |
| Music and most video audio | 192 kbps | 1.4 MB |
| Music you care about | 320 kbps | 2.4 MB |
Going above the source's quality adds size, not detail. The full guide is what MP3 bitrate should I use.
Can I convert a video to MP3 in bulk?
The browser tool handles one file at a time, which keeps it fast and private. For dozens of files, VLC's convert window takes several at once, and FFmpeg can do a whole folder with a one-line loop.
Why is there no audio to extract?
If the tool says the video has no sound, the video was recorded silently. That's common with screen recordings when the microphone was off. See why screen recordings are silent.
