FlowPick - Web media downloader browser extension
FlowPick is an open-source browser extension designed for detecting, previewing, and downloading web media resources, including M3U8/HLS streams, MPD/DASH video manifests, direct audio files, and images. Operating locally on your device via Web Workers and browser-native APIs, the tool processes media streams without relying on external utilities like FFmpeg or command-line tools. It serves as a unified interface for capturing resources across more than twenty distinct media formats directly from active browser tabs.
Key Features
- Smart Sniffing: Automatically detects network requests for HLS playlists, DASH descriptors, video containers, audio tracks, and images as pages load.
- Local Merging: Combines streaming segments into progressive MP4 files entirely client-side using JavaScript parsers and local processing workers.
- Smart Filtering: Filters detected items by file size, type, or duration, and allows targeted searches using URL keywords and regular expressions.
- Parallel Downloads: Accelerates fragment retrieval through multi-threaded processing to speed up file acquisition.
- Built-in Player: Previews video and audio items directly within the extension popup interface prior to saving.
- Multi-Format Support: Handles over twenty standard file types across streaming protocols, video codecs, audio formats, and image extensions.
Built for developers, researchers, and power users who need granular control over web media assets, FlowPick emphasizes privacy with local execution and no built-in extension analytics SDK. It runs across major Chromium-based browsers like Chrome, Edge, Brave, and Opera, as well as Firefox. The project is open source and complemented by web-based conversion tools.
