info About this tool
Extract the audio track from any MP4 video and convert it to MP3 format. Ideal for saving music videos as audio files, pulling a podcast episode from a video recording, or grabbing the soundtrack from a downloaded clip. The converter discards the video stream entirely and re-encodes the audio as high-quality MP3 at 192 kbps: a good balance between file size and audio fidelity for most content.

File size: MP3 output is dramatically smaller than the source MP4: typically 90 to 98% smaller since video data is removed.

Quality: Audio extracted and re-encoded at 192 kbps MP3. Video track is discarded.
