Ben Fletcher does an excellent job in his new Wiki article explaining how the Property Converter works and then compares it to the same concept using a custom action.

Composite applications support “hidden” components and when this component is on the screen you can wire a source property to it, transform the data, and then wire the converter component to the target component. Here is a flow of the component and the data.
