Stream Video Downloader - HLS & m3u8

Detect and download HLS (m3u8) streams and MP4 videos from any site. Play or convert to MP4 in your preferred resolution.

FREE. NO signup required. While you browse, the extension quietly detects HLS (.m3u8) playlists and direct MP4 streams on the page. When something is found, the toolbar icon shows a count — open the popup to play, convert, or download what it caught. ▶ WHAT IT DOES • Detects HLS / m3u8 live and on-demand streams as well as direct MP4 files • Lists every quality/resolution variant a stream offers • Plays streams in a built-in player (great for checking before you save) • Converts m3u8 streams to a single MP4 file in the resolution you choose • Marks live broadcasts with a LIVE badge • One-click download of detected MP4 files ⚙ HOW IT WORKS Detection runs entirely in your browser. When you choose Play or Convert, the extension hands the stream URL to the companion web app, which does the playback or MP4 conversion locally using WebAssembly — your video is never uploaded to a server. 🔒 PRIVACY • No account, no sign-up • No analytics or tracking • Nothing you watch or download is sent to us — it stays on your device 📋 HOW TO USE 1.

Press Play to preview, or Download / Convert to save Note: This tool is intended for downloading content you own or have permission to save.
