The Eredivisie side have secured the services of the youngster after coming to an agreement with FC Koln, who have been relegated from the Bundesliga this season
The 20-year-old has signed a contract that will tie him to the Dutch side for the next three years.
Heerenveen technical director Johan Hansma was over the moon after clinching the deal, saying: "He is a creative player who has an eye for something special and who can make goals just as well as scoring them."
However, despite always being regarded as a rising star in Koln's youth ranks, Uth was never handed a league debut with Frank Schaefer's senior team.
The talented attacker now heads for pastures new in Holland, as Heerenveen search out replacements to plug the gaps left in the squad by the impending departures of Bas Dost, Luciano Narsingh and Oussama Assaidi.
