Karthi made his acting debut with the Tamil film Paruthiveeran (2007), starring Priyamani and Saravanan. He won several awards, including the Filmfare Award for Best Actor, the Vijay Award for Best Male Debut and Tamil Nadu State Film Special Prize for his performance.

He also starred in Siruthai (2011), an action-masala film remake of the Telugu film Vikramarkudu (2006). In this movie, he played two roles, a thief, and a police officer, and received positive reviews. The film became one of the highest-grossing Tamil films of 2011 and cemented Karthi's position in the Tamil film industry.

Karthi again partnered with Mani Ratnam, this time staring in his film, Kaatru Veliyidai (2017). His subsequent film Theeran Adhigaram Ondru (2017), directed by H. Vinoth, was an enormous success. Karthi received a Filmfare Award South for Best Actor - Critics for his performance in the film.
