What is an EXO File and How to Convert .exo to .mp4?

Author by Rocabella

Updated on Apr 28, 2023

YouTube Android app would generate a set of video chunk files in .exo format for offline playback and many people have tried to convert the .exo files to MP4 but ended up with failure. So is it possible to convert .exo to .mp4 or any other video format? If it is possible, how? And if not, what should we do then? To know the answer, read on to get more information.

Wanna a hassle-free YouTube video download solution? This application is of great help:

Part 1. What is an EXO file?

The .exo File

The .exo file is primarily associated with the YouTube app on Android devices. As you save a video within the YouTube app, the content will be divided into several video segments stored in .exo filename extension. To put it in another way, EXO files are the pieces of a complete video file and they are produced from the YouTube Android app for offline playback. The EXO files are compressed and encrypted for preventing illegal distribution and sharing.

Part 2. Is It Possible to Convert .exo to .mp4?

Does an EXO to MP4 Converter Exist

No, it is not possible to convert the EXO file to MP4 or any other video format. An EXO to MP4 converter does not exist either because the .exo files are encrypted and can only be opened, decrypted and reassembled within the YouTube Android app only. The app will piece together all the EXO files together, so that the chunks become a whole file once again. Any third-party software cannot open and convert .exo to .mp4.

But don’t get frustrated yet. Rather than finding a method to convert .exo to .mp4, a YouTube downloader can direcly save your desired YouTube videos in MP4 format. The next part shares an easy way to save YouTube videos. Read on if you’re interested.

Part 3. (Optional) Download YouTube Videos in MP4

Instead of sticking to the impossible .exo to .mp4 conversion, a better move is to directly download the video in MP4 format. You will need a professional YouTube video downloader for this.
