Loader . ac focuses on individual videos to ensure reliable performance . Downloading playlists can be more complex due to licensing and file sizes, and it may be restricted by the service’s terms . Use the tool for personal, single-video downloads to start .
Quality choices influence bitrate . MP3 options generally include 128 kbps, 192 kbps, and 320 kbps . Higher bitrates yield better sound at the cost of larger files . For video, 1080p at 30/60 fps delivers crisp visuals but larger files than 720p or 480p .
