Combine MP4 Files

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.

How to join MP4 files

1. Upload MP4 files

   Use the Choose files button to add files from your computer or phone. If you click the tiny arrow on the right of the button, you will be able to upload them from Google Drive or Dropbox.

   

   The tool allows you to combine different file types together, so upload all of them: images, videos, and GIFs.

2. Combine MP4 videos

   When the editor opens, add more files if needed using the ways described in the first step. Then, reorder them by dragging and dropping on the timeline.

   

   Choose aspect ratio and a crop option. If you have added images, set their duration. Check the box named "Crossfade" in order to make the transition between files smoother.

   

   The MP4 Merger also lets you add music, cut its length, and change volume. If your audio is too short, click on the infinity icon to loop it.
