Use this tool to turn an MP4 video into an MP3 audio file. It’s useful when you only need the sound from a clip—like a lecture recording, a meeting, a short voice memo, or a soundtrack from a video snippet.
You can choose a sensible quality preset and export a compatible MP3 that plays almost everywhere. For best results, start from a clean source: noisy audio or low-bitrate sound in the original video will remain limited in the output.
If you want faster extraction without re-encoding (when the audio is already AAC), MP4→M4A can be a better choice. Use MP3 when you need maximum compatibility across devices.
FAQ
›Does converting to MP3 improve audio quality?
No. Conversion cannot add missing detail. It can only preserve or reduce quality based on settings and the source.
›MP3 vs M4A: which should I choose?
MP3 for widest compatibility; M4A can be more efficient if you keep AAC without re-encoding.
›Why is the output file size large?
Higher bitrate/quality settings and longer duration increase file size.
›Can I convert very large videos?
Large files can take longer and may hit device/browser limits. Trim the video or extract a shorter segment when needed.
›Is the result a single audio track?
Yes. The tool outputs one MP3 file from the chosen audio stream.
