One-click HLS, M3U8 & MP4 video downloader. Lossless original quality, fully local — your videos never leave your browser.

Save any HLS, M3U8 or MP4 video to your computer in a single click. Stream Saver detects video streams running on the page — including adaptive HLS playlists, fragmented MP4, and AES-128 encrypted streams — and downloads them as a clean, playable .mp4 file you can keep forever. ✓ Works on thousands of streaming sites ✓ Lossless — no re-encoding, no quality loss ✓ Original resolution and audio preserved ✓ Picks the highest-quality variant by default (or choose your own) ✓ 100% private — videos never leave your browser ✓ No account, no signup, no upload ━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━━━ • Detects HLS / M3U8 playlists, fragmented MP4, and direct MP4/WEBM/MOV • Downloads all segments in parallel and stitches them into one MP4 • Decrypts AES-128 protected HLS streams on the fly • Plays back on any device — VLC, Windows Movies & TV, iOS, macOS • Shows the actively-playing video at the top — no guessing which stream • Quality selector for multi-bitrate streams (1080p / 720p / 480p / etc.) • Progress bar with cancel support ━━━━━━━━━━━━━━━━━━━━━━ WHY STREAM SAVER ━━━━━━━━━━━━━━━━━━━━━━ Most "video downloader" extensions re-encode your video — meaning quality loss, hours of waiting, and a fan-noisy CPU. Stream Saver uses a zero- re-encode transmux pipeline: the original H.264/AAC bytes move straight into an MP4 container, so a 1-hour stream finishes in seconds and looks identical to the source.
