Replay files, which bring the amusement of sharing and improvement, mean a lot to game players. However, people can only watch these files on a designated application, which limits their viewing experience. Hence, more and more people want a method to convert a replay to MP4.

The replay files are closely related to real-time PC games, like OSU, LoL, Fortnite, and so on. With these files, you can know better about your performance in the past games, which helps you to improve your game skills. There are many replay files in your game journey. One of the most popular replay files is the League of Legends replay (also known as a ROFL file).
