Does this support KML Polygon placemarks?

No - GPX only has waypoints and tracks, so only Point and LineString placemarks convert; any unsupported placemark geometry returns an error rather than dropping features.

Why would I need this instead of just using Google Earth?

Handheld GPS units and outdoor apps (Garmin, hiking apps) typically take GPX, not KML - this bridges a Google Earth route into that format.
