How to Download MP4 Codecs for Windows 11/10/8.1/7?

A codec is software used to compress and decompress media data such as audio, video, and images. MP4 codecs are video and audio codecs used to compress video and audio streams in MP4 containers. Media players need MP4 codecs to play MP4 smoothly.

However, since MP4 can contain various codecs, including MPEG-4, H.264, HEVC, AV1, AAC, MP3, and AC3, Windows does not support some of the MP4 codecs, such as HEVC and AC3, so sometimes some MP4 files won't play. Installing missing MP4 codecs is one of the effective ways to get your MP4s playable on Windows again. Fortunately, there are several ways to download MP4 codecs. The next part will show you where and how to download MP4 video codecs for Windows 11, 10, 8.1/8 and 7. Read on.

Though Windows does not support some of the MP4 codecs natively, it provides codec extensions for download in the Microsoft Store to help you enable some MP4 playback. Below is a roundup of the codecs for MP4 to download:

A codec pack contains a number of different codecs to help play different types of media files. Here are the best four free codec packs with MP4 video codecs included.

The Media Player Codec Pack supports a wide range of codecs, including MP4 codecs, to play nearly all modern video and audio files, including HEVC, MPEG4, 10 bit x265, AVCHD, and many more. It has three editions, among which the standard version is enough for regular uses.

Tips. These codec packs will automatically install MP4 codecs for Windows Media Player or the Video app on Windows. Once you installed the codec pack, reopen your media player and see if it plays your MP4.

Some believe that the third-party codecs could mess up the system environment, and they would prefer to convert the codec to a Windows-friendly format to make the video playable. If you have the same concern, you can try changing the MP4 video codec too.
