Video Download Assistant 作者： Michael @ Code Red

Download Assistant finds downloadable media on the pages you browse and saves it in one click

Download anything it detects
• Direct video and audio files (MP4, WebM, MP3 …)
• HLS (m3u8) and DASH (mpd) streams, saved as clean, seekable MP4 files
• Pick your quality (4K/1080p/720p …) before downloading
• Audio-only extraction to M4A — grab just the music
• Handles AES-128 encrypted streams

Fast and reliable
• Parallel segment downloading with live progress, cancel and queue
• Lossless remuxing via bundled ffmpeg — no re-encoding, no quality loss
• Filenames taken from the page title, optional subfolder, "always ask where to save"

Free & private
• No premium tier, no watermarks, no download limits
• Zero data collection — nothing ever leaves your browser

Honest limitations
• DRM-protected services are not supported
• Live streams not supported yet

Some websites' terms of service restrict downloading — please use responsibly.
