SnapVidBox is a free online tool that saves public TikTok, Douyin, Facebook and Instagram videos as MP4, and their sound as MP3, without an app or an account.
Paste a public share link and every file that platform serves for the post is listed: the MP4 in each quality, the sound as M4A or MP3, and the cover image. Nothing is installed, no account exists, and the link is dropped once the request finishes.
