The retouched version of the blockbuster film, which starred Kate Winslet and Leonardo DiCaprio as star-crossed lovers on the fated Atlantic voyage, will be re-released worldwide on April 6 to mark the 100th anniversary of the ship setting sail.
Director James Cameron told Deadline: "There's a whole generation that's never seen Titanic as it was meant to be seen, on the big screen. And this will be Titanic as you've never seen it before, digitally remastered at 4K and painstakingly converted to 3D.
"With the emotional power intact and the images more powerful than ever, this will be an epic experience for fans and newcomers alike."
A spokesperson for Paramount Pictures added that the movie release will be "particularly special" because next year is also the studio's 100th anniversary.
Last year, the film's producer Jon Landau warned that it could take some time to release the edited version of the movie as they "want to do it right".
The original movie is the second highest-grossing movie of all time and won a record 11 Academy Awards, including 'Best Director' and 'Best Picture'.
