How to Use Extract Audio from Video
Extract the audio track from any video and save it as MP3, AAC or WAV. Everything is processed in your browser, so your video never leaves your device.
- Select or drop a video file such as MP4, WebM or MOV into the upload area.
- Pick MP3, AAC or WAV in the 'Output Format' dropdown to match your player or editing software.
- Enter a value in 'Start Time (seconds)' to skip a silent or irrelevant intro.
- Fill in 'End Time (seconds)' to stop the export before credits or trailing noise.
- Start the extraction and download the finished audio file once processing completes.
Leave both time fields empty to extract the full track — WAV keeps the original quality but produces much larger files than MP3.
