Video Saver

Download HLS and DASH streaming videos. Segments are merged into a single MP4 file, video and audio together.

Video Saver is a powerful, lightweight, and privacy-focused media utility designed to help users download standard fragmented streaming videos (HLS/M3U8 and MPEG-DASH/MPD) and direct media files (MP4, WEBM, MKV) for offline viewing. Many modern websites deliver video in small fragmented chunks to optimize delivery. Video Saver detects these stream playlists, downloads the segments concurrently, and seamlessly merges them into a single, standard video file directly on your local device. KEY FEATURES: • HLS & DASH Stream Support: Detects, parses, and stitches fragmented M3U8 and MPD video/audio streams. • Direct Video Detection: Captures standard standalone video files embedded in web pages. • Multi-Threaded Speed: Concurrent segment retrieval for fast and reliable downloads. • Native Browser Integration: Utilizes Chrome's built-in download manager for safe and standard file saving. • Local & Private Processing: 100% client-side operation via Origin Private File System (OPFS) and Offscreen Documents. No video data or browsing activity is ever collected or sent to external servers. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IMPORTANT POLICY & LEGAL NOTICES: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • YOUTUBE RESTRICTION: In strict compliance with Google Chrome Web Store Developer Policies and the YouTube Terms of Service, this extension DOES NOT and CANNOT download videos from YouTube. All YouTube domains and proprietary streams are blocked and unsupported. • COPYRIGHT & DRM NOTICE: Video Saver does not circumvent digital rights management (DRM). Encrypted or DRM-protected streams (such as Widevine, FairPlay, or PlayReady) cannot be downloaded. Please respect copyright laws and only download media you have the right to access offline. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TRANSPARENCY & PERMISSIONS BREAKDOWN: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ To deliver its core functionality safely within Manifest V3, Video Saver requests the following permissions: • "webRequest" & "host_permissions" (<all_urls>): Required to detect media manifest URLs (M3U8/MPD) in network requests and retrieve media segments hosted on external Content Delivery Networks (CDNs). • "downloads": Required to transfer the finalized, merged video file to your local computer. • "offscreen": Required to perform audio/video transmuxing and segment merging in an isolated document without exceeding service worker lifecycle/memory limits. • "unlimitedStorage": Required to buffer and assemble large media chunks locally (via OPFS) during download without running into browser quota errors. • "tabs": Required to read the active tab's title solely to suggest an accurate and meaningful default filename for the saved video. • "storage": Used locally to maintain session state and user preferences.
