The Niners will host the winner of Sunday's game between Tampa Bay and Detroit next weekend for a spot in the Super Bowl.
Green Bay converted a third-and-15 when Ambry Thomas was called for a 41-yard pass interference penalty against Bo Melton.
The Niners made them pay for that with Purdy hitting George Kittle on a 32-yard pass on the run for a TD that gave San Francisco the lead.
Jones finished with 108 yards on 18 carries for the Packers, and Love was 21 of 34 for 194 yards.
49ers: WR Deebo Samuel injured his shoulder on the opening drive and missed most of the game.
