MP4 to MP3 Converter (Video to Audio)
Extract Audio from Video — Free Online MP4 to MP3 Converter
Upload any video file and extract the audio track as a high-quality MP3. This tool converts the audio stream from MP4, MOV, AVI, WebM, MKV, FLV, WMV, and most other video formats directly in your browser — no software installation, no signup, and no watermarks. The output is encoded at 192 kbps by default, which provides a good balance between file size and audio fidelity for most use cases.
How to convert MP4 to MP3
- Upload your video file from your device or paste a URL.
- Click "Convert!" to extract the audio track.
- Download the resulting MP3 file or continue with other tools.
When to use MP4 to MP3 conversion
- Save music from a video — extract the audio track from a music video or concert recording for offline listening.
- Podcast and lecture extraction — pull the audio from a recorded webinar, lecture, or podcast video so you can listen on the go.
- Voice notes and interviews — convert screen recordings or video interviews into lightweight audio files for transcription or archiving.
- Social media audio — extract audio clips from video content for use in other projects, presentations, or as sound bites.
- Reduce file size — if you only need the audio, discarding the video stream dramatically reduces the file size (often 90% or more).
Understanding audio bitrate
MP3 bitrate determines the balance between audio quality and file size. Higher bitrate means better quality but larger files. Here is a general guide:
| Bitrate | Quality | Best for | ~Size per minute |
|---|---|---|---|
| 128 kbps | Acceptable | Speech, podcasts, voice memos | ~1 MB |
| 192 kbps | Good (default) | General music, mixed content | ~1.5 MB |
| 256 kbps | High | Music with complex instrumentation | ~2 MB |
| 320 kbps | Maximum | Audiophile listening, archival | ~2.5 MB |
This tool outputs at 192 kbps, which is sufficient for the vast majority of use cases. If you need lossless audio instead of MP3, consider converting to WAV or FLAC format.

Frequently asked questions
Is this MP4 to MP3 converter free?
Yes, 100% free with no watermarks, no signup, and no conversion limits. All uploaded files are automatically deleted from our servers one hour after upload.
What video formats are supported?
In addition to MP4, this tool accepts MOV, AVI, WebM, MKV, FLV, WMV, 3GP, and most other video formats. The audio track is extracted regardless of the video codec used.
Will converting to MP3 reduce audio quality?
MP3 is a lossy format, so some quality is lost compared to the original audio stream in the video. However, at 192 kbps the difference is imperceptible for most listeners. If the original video audio was already compressed (e.g., AAC at 128 kbps), the output quality is limited by the source — converting cannot improve audio that was already compressed.
What bitrate does this tool use?
The output is encoded at 192 kbps, which provides good quality for music and excellent quality for speech. This is a widely used standard that balances file size and fidelity.
Can I extract audio from a YouTube or online video?
You can paste a direct URL to a video file (a link ending in .mp4, .webm, etc.) and the tool will fetch and convert it. However, streaming platform URLs (YouTube, TikTok, etc.) are not supported due to their terms of service.
Can I use this on my phone?
Yes, this converter works on all devices including iPhone, Android, iPad, and desktop computers. No app installation is needed — just use your web browser.
Can I convert multiple files at once?
This tool processes one file at a time. Upload a video, download the MP3, then upload the next file. For batch audio format conversion between MP3, WAV, FLAC, and other formats, you can use the individual converters listed above.
