TikTok changes one post at a time. With 500 posts, that math is brutal.
FixMyTok scans your account. Filter by date, caption, creator or visibility, select what you want gone, then confirm once. Videos go private or get deleted. Reposts disappear. The batch runs while you watch, and you can stop it, continue later, or save a report of what changed.
You sign in through TikTok's own login, so the app never sees your password. Nothing moves until you pick it.
