## Description

Media Converter and Muxer is a user-friendly Chrome extension that leverages FFmpeg technology to simplify audio and video file conversions and edits. With this tool, users can convert videos and audio files to MP3 format, extract original audio tracks from videos without quality loss, and merge separate audio and video files seamlessly. It also allows volume adjustments, video cutting into defined segments, audio-video sync correction by shifting tracks, and efficient video rotation by 90, 180, or 270 degrees.

To ensure smooth operation, the tool requires installing a minimal native client, which bridges the extension with FFmpeg. This extension is a WebExtension port of the popular Firefox add-on, offering powerful media handling capabilities directly within the browser, making it a comprehensive solution for all your audio-video conversion and editing needs.
