Why extract audio from video?
Sometimes you only need the audio track from a video. Whether it's a podcast recorded as video, background music from a presentation, a voice memo captured on camera, or dialogue from a lecture. Extracting just the audio dramatically reduces file size and makes content easier to share, store, and play on audio-only devices.
Unlike server-based tools that upload your files, this converter processes everything locally in your browser using WebAssembly. That means faster processing, complete privacy for sensitive recordings, and no file size limits beyond your browser's memory.
