Since the times of camcorders with cassettes for recording, storage has always been a thing of concern. And when digital storage in the form of SD cards came in, the storage problem was pushed aside. Then began the era of AVI, which was short-lived due to its inefficiencies. MP4 and MKV replaced it.

The two formats had similar properties, but MP4 triumphed due to its wide adaptability, with due credit to Microsoft for adopting it as the default format on their OS.

As a result, you will find the majority of the devices like video game consoles, smartphones, tablets, and even smart TV have MP4 video support by default. You can convert all your downloaded videos from MKV, AVI, WMV, etc. to MP4 using free video converters. We have compiled a list of the converters online with two online options.
