Phil Dawson, who has kicked for the Browns since 1999, announced via Twitter that he will become a 49er.
Dawson will replace David Akers, whom the 49ers released after he struggled in 2012.
Dawson made his first Pro Bowl this year after producing one of the most accurate seasons of his 14 NFL years, hitting 29 of 31 field goals for a conversion percentage of 93.5 -- second best among NFL kickers in 2012. The 38-year-old doesn't appear to be losing strength in his leg after making seven kicks of at least 50 yards last season.
The 14-year veteran will reunite with former Browns special team coordinator Brad Seely in San Francisco.
Dawson also tweeted his thanks and respect to the Browns and their fans.
