Audio extraction pulls the audio track from a video file and saves it as a standalone audio file. The video frames are discarded, leaving you with just the sound — dialogue, music, narration, or ambient audio. The output is an MP3 file, which is universally playable on all devices and media players.
Common use cases include saving music from concert videos, extracting podcast audio from video recordings, creating audio-only versions of lectures and tutorials, capturing voiceovers, and isolating sound effects. Audio files are dramatically smaller than video files, making them easier to share and store.
Convertful uses FFmpeg compiled to WebAssembly to demux (separate) the audio stream from your video file and encode it as MP3. The process preserves the original audio quality. Everything runs in your browser — no file upload, no server processing.
