About this tool
Extract the audio track from any MP4 video and convert it to MP3 format. Perfect for saving music videos as audio files, extracting a podcast episode from a video recording, or pulling a soundtrack from a downloaded clip. The converter strips the video stream entirely and re-encodes the audio as a high-quality MP3 at 192 kbps — a good balance of file size and audio fidelity for most content.
File size: MP3 output is dramatically smaller than the MP4 source — typically 90–98% smaller since video data is removed.
Quality: Audio extracted and re-encoded at 192 kbps MP3. Video track is discarded.

FAQ
What audio quality is used?
We export at 192 kbps, which is high quality for music and voice content and indistinguishable from the source for most listeners.
Does it work with music videos?
Yes. Any MP4 file with an audio track works — music videos, lectures, recordings, screen captures with voiceover.
What if the video has no audio?
The conversion will fail or produce a silent MP3. Make sure your MP4 contains an audio track before converting.
Can I convert M4A files too?
Yes. M4A files (Apple audio in an MP4 container) are also accepted and converted to MP3.
