How to Extract Audio
- Go to our MP4 to MP3 converter
- Upload your video file
- Wait for the extraction to complete
- Download the MP3 audio file
How It Works
Our converter uses FFmpeg technology running directly in your browser through WebAssembly. It reads the video file, extracts the audio stream, and encodes it as MP3. The video data is discarded, leaving you with just the audio at a fraction of the original file size.
Privacy Benefit
Unlike server-based converters, your video file never leaves your computer. This is particularly important for personal videos, business meetings, and any content you'd rather keep private.
Other Audio Extractions
You can also extract audio from other video formats: WebM to MP3 or MP4 to WAV for uncompressed audio quality.
