The MP4 file format is a part of the MPEG-4 standard. Files with the .mp4 extension can contain video and audio streams, subtitles, and metadata. The format is supported on both Windows PCs and Macs as well as the majority of devices – smartphones, tablets, HD TVs, video game consoles, and more.

Want to learn how to convert a video to the MP4 format? One one of the ways is to use an online video-to-MP4 converter, like the one at the top of this page. However, a regular online converter to MP4 can normally process only small files. You can also convert movies to MP4 using a desktop video converter – this option is more suitable if you have large files for conversion.

In this article, we’ll discuss how to convert to MP4 using Movavi Video Converter, describe the MP4 format, and answer some frequently asked questions.

If you're converting videos for social media platforms, it's a good idea to optimize the video size and format to match each platform’s requirements. For example, Instagram prefers square or vertical videos, while YouTube works best with widescreen formats. Paying attention to resolution and aspect ratio will ensure your video looks perfect when uploaded.
