About M3u8 Video Downloader

M3u8 Video Downloader is a browser extension specialized in detecting M3u8 and HLS streams on web pages and converting them to standard MP4 files for offline use.

The extension monitors active pages for M3u8 playlist files, reassembles the segmented video data, and produces a single downloadable MP4 without requiring external conversion tools.

Because the entire HLS-to-MP4 conversion happens within the browser, no stream data is sent to remote servers during the process.
