What is an MP4 combiner

The MP4 format is a multimedia container. Although it is usually used to store audio and video, it can store other media like subtitles. It is also the most widely used format on the Internet.

Clideo's MP4 Joiner is online, meaning you don't need to download or install anything taking up the memory of your device. It works with all operating systems including macOS, Windows, Android, and iOS.

The service also works free of charge — each file you're planning to merge can be up to 500 MB. If you need to upload bigger files, don't worry, you can just subscribe to Clideo Pro.

The best video editor. I've already tried out a lot of video editors, but this is the best one. It has everything in there, unlike others that need a lot of other websites to do different things. Thank you so much.
