There is no one group called "converts". Without being more specific (converts to Christianity, converts from Hinduism to Buddhism, etc), this question can't be answered.

Generally it is Christians and Buddhists who seek out converts, and none of the other main religions (Judaism, Hinduism, Islam.)

Not all schools of Hinduism actively seek converts. The International Society of Krishna Consciousness is known for proselytizing, but some people consider a hereditary priesthood important in Hinduism.
