MP4 to MP3 Converter — Free, No Upload
Save the audio from a lecture or interview MP4 as a separate MP3. The picture is omitted and the audio is re-encoded at your chosen bitrate; speech isolation and music removal are not part of this operation.

How to use this tool
Choose an MP4 containing audio and select an MP3 bitrate. Compare a short sample before processing a long recording, and note that this interface does not offer an explicit track selector for multilingual video.
Results and examples
Listen to the MP3 to confirm that the expected speech and background audio are present. Captions and visual demonstrations are absent, so retain the video when those elements are needed to understand the recording.
Worked example
Choose 192 kbps for a lecture MP4 to create an audio-only MP3 for listening away from the screen. Encode the same passage at 128 and 320 kbps to compare size and sound, without treating the larger setting as restoration.
Limitations
- Video, subtitles and screen content are absent, and a silent source cannot generate new speech.
- There is no explicit language-track selector for multi-audio inputs.
Fields

Data handling
