Converting MPEG4 to MP4 can bring several benefits, such as:

  • Wider compatibility. If the MPEG4 video is wrapped in a less-popular format like MKV, it’s best to convert it to MP4 format to achieve the best device compatibility.
  • Smaller size. MP4 can use more efficient codecs like H264 and H265/HEVC, which can result in smaller file size to save storage space.

Wondering how to do this? 🤔

Don't worry. Below, I’ll show you how to convert MPEG4 to MP4 video on your Windows PC. Also, you can learn more tips to retain high-quality output and reduce video file size. So just keep reading!
