BoltStream - Video Downloader

Universal web video downloader — supports MP4, M3U8, HLS, and more.

Download videos from any website. BoltStream detects media as you browse and lets you save them in one click — no accounts, no software to install, and your videos never pass through our servers. Supports MP4, WebM, HLS (M3U8), and streaming video. When you click Download, BoltStream opens its download page on boltstream.app, our own website. The page runs in your browser tab: it fetches the video directly from the original site and saves it to your computer. Your videos and their addresses never reach our servers. FEATURES Automatic Media Detection BoltStream works quietly in the background while you browse. When it finds a video or audio file on any page, it shows up in the popup with format, resolution, and file size — no need to copy-paste URLs or figure out where the video is hosted. HLS / M3U8 Download Downloads streaming video and converts it into a single MP4 file you can watch anywhere. When multiple quality options are available, you choose the resolution you want. Video Download Downloads standard video files (MP4, WebM, etc.) with multi-threaded downloading for faster speeds. Record Mode Some streaming sites don't offer a direct download link. Record Mode captures the video as it plays, and stops automatically when it ends. Just hit play and let BoltStream handle the rest. Large File Support Downloads are saved using smart temporary storage, so even very large video files won't crash your browser or eat up your memory. When the download finishes, your browser's standard Save dialog appears. Pause, Resume & Partial Save Pause and resume downloads at any time. You can also save what you have so far if you don't need the full video. Works With Protected Sources Some sites block downloads from outside their player. BoltStream handles this automatically so you don't have to worry about it. HOW TO USE 1. Install the extension 2. Visit any page with video content 3.
