4 Methods to Convert MP4 to H.264 on Windows and Mac

By Cecilia Hwung | Last Update:

Why should you convert MP4 to H.264?

H.264 (aka MPEG-4 AVC) is a predominant codec used in storing, editing, streaming, and broadcasting videos. When you can't import an MP4 file to Premiere Pro, open it with the default player, or upload it to social media platforms, it's always considered prior to its codec (which is legacy or newly-developed). Now H.264 is the best target codec. What's more, H.264 codec is efficient to reduce the size of HD videos while maintaining the best quality.

At the very beginning, we should make it clear that MP4 and H.264 are different. The former is a file container format while the latter refers to a video compression standard. So it's not a straight conversion from one to another. It involves three different situations:

  • Re-encoding MP4 with H.264 codec, such as MP4 HEVC to H.264, MP4 MPEG-4 to H.264.
  • Converting MP4 to H.264 codec with another container, such as MP4 to MOV H.264, MP4 to MKV H.264.
  • Converting .mp4 to .264, a file with raw video stream only.

Keep this in mind, and you can convert MP4 to H.264 according to your needs with the best video converter below.
