What is audio extraction from video?

Video files often contain a separate audio track alongside the picture stream. Extracting the audio lets you reuse speech, music, or ambient sound without keeping the video portion.

This is common when you want to convert a clip into a podcast segment, save narration, or reuse a soundtrack in another project.

Tool description

This tool extracts the audio track from an uploaded video file directly in the browser. Choose an output format, wait for processing to finish, and download the resulting audio file.

It is useful when you want to separate sound from video without uploading media to a server.
