I doubted you, but then looked it up. For anyone else doubting:

Article II, Section 2, Clause 1, of the Constitution says the President “shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.” The Office of the Pardon Attorney, which is part of the Justice Department, has handled such matters for the President since 1893. Presidential pardons only extend to federal crimes, not civil cases or non-federal cases.
