Convert MP4 to H264 with 4 Best Free Video Converters
MP4 VS H264, What are the Differences?
First of all, you have to figure out that they are two different concepts, MP4 is a video container format, and H264 is a video codec format.
Still no clue? No worries! Take the video file as a chocolate box, the ingredients like cocoa beans are the video and audio streams, which are encoded by codecs like H.264 to chocolates. Then, they are packed with the chocolate box, which is the container MP4.

What Video Format is H264?
H264 is the video compression codec inside and it has a container to pack it. Hence the container format can be various, such as MP4, MOV, 3GP, MKV, TS, WebM, etc.
Are All MP4 Files H264?
No. Like I explained, MP4 is the container format that packs the videos in codec format. So, it can be different codecs inside, including H.264, H.265 (HEVC), VP9, AV1, etc.
How Can I Tell the Codec of My MP4 Video?
It can be found out by looking at the file property information. For example, in VLC, head to Tools → Media Information → Codec, and it will display the video codecs. So, you can tell what codec the MP4 video is encoded, and if you want to convert it to codec H.264.

But you should not ignore its disadvantages. Firstly, it cannot convert MP4 to H264 in MP4 format. Secondly, it’s relatively slow compared to desktop software. Thirdly, it has limits on the file size (less than 250 MB).

So, it is not reliable to download files from servers online.
