By Cecilia Hwung | Last Update:

Why in need of an MP4 splitter? There're stacks of possibilities to have large-sized MP4 video files. We shoot significant landscape videos during trip, purchase a digital HD movie or TV show, and so on.

When it comes to uploading or sending those files over internet, the size and duration make troubles. Some sites prevent from uploading a video having bigger size or longer length exceeding the allowable limits. Some sites give a huge space but slow uploading speed commonly happens because of bad network connection or bandwidth limits.

It is advisable to split MP4 files into two parts and more to reduce file size and length or for adding multiple different effects for sharing online without hassle. The below 3 free MP4 splitters could be good to use and we provide corresponding step by step guides.
