On March 3, 2016, Lionsgate released the first official photo of the five Rangers, and the following month, the company released the first official photo of Banks as Rita Repulsa. On May 5, the company unveiled the first official images of the Rangers' suits. Director Dean Israelite said that "The show was about kids coming of age, about metamorphosis, these suits needed to feel like they were catalyzed by these kids and their energy, their spirit", while production designer Andrew Menzies commented that the new suits are "an alien costume that grows on them, that's not man-made. You can't win everyone over, but we are trying to appeal to a more mature audience and gain new fans." A teaser poster was released in June, with additional character posters released in July, September, and October. On October 8, 2016, a Discover The Power teaser trailer for the film was released.
A fictional Angel Grove High School Newspaper website was created, alongside the official Power Rangers website, which features a GIF creator that allows users to make a GIF out of scenes from the teaser trailer. There is also an official toyline, produced by Bandai, and an extensive merchandising range was produced to promote the film.
Landis, whose draft was rejected, criticized the trailer, saying that it looked too similar to Chronicle (2012), a film that he had written. The trailer garnered mixed reactions, with some praising it for its darker, contemporary reimagining of the classic characters, while still looking action-packed and fun at the same time, and others criticizing it for its lack of connection to the original series, saying it appeared "brooding". The trailer received over 150 million views in the first two days after it was uploaded. Lionsgate revealed the T-Rex Zord toy, among others, on October 28, 2016, and the Power Rangers Twitter account revealed the Megazord toy on November 4, 2016. On November 15, 2016, Lionsgate revealed the toys based on the film's individual Zords.
