Extract Audio from Video (MP3)

Extract audio track from any video file and download as MP3.

What can you use this for?

Transcribe audio

Extract the audio track first, then upload to a transcription service to get subtitles or a transcript.

Podcast / voice-over reuse

Extract clean audio from a recorded video to publish as a podcast episode or reuse the voice-over.

Audio editing

Pull the MP3 into any audio editor (Audacity, GarageBand) to clean up noise, cut sections, or adjust levels.

Smaller file for upload

Audio-only MP3 is far smaller than the original video — ideal for uploading to speech-to-text APIs with size limits.

Replace video soundtrack

Extract the original audio, edit it, then burn it back into the video with another tool.

Meeting / lecture notes

Extract audio from a meeting recording or lecture video, then feed it to an AI summarizer.
