へ indicates the direction something moves toward, whereas まで stresses reaching or extending up to a specific endpoint.
に simply marks a point of arrival or time, while まで emphasizes the continuous extent leading up to that point.
まで shows a continuous extent up to a point in time or space (e.g. 5時まで待つ = wait until 5:00), while までに marks a deadline by which a single action must be completed (e.g. 5時までに来る = come by 5:00).
