How to convert MP3 to MP4 easily

With advancements in technology, changing file formats has become a very common phenomenon. Gone are the days where converting video files from one format to another was a task best suited for videographers and editors. Every general audience now has to convert some of their files for some specific tasks.

People might want to convert their MP3 files to MP4 files because:

  • An MP3 file can only store audio files. However, an MP4 file can also store video files and even has the ability to include subtitles.
  • MP4 file also has the ability to store files that have been compressed via different methods.
  • There are many more players available for MP4 format than for MP3 format.
  • An MP4 file gives more editing options than an MP3 file.

While many video converters are available in the market that claims to get this job done, only a few of them are fast and reliable. Here, we will have a detailed look at some of the ways to convert MP3 files to MP4 files. So let’s get started without further ado.

First things first, what are MP3 and MP4 files?

An MP3 file stands for MPEG Audio Layer-3. It is a compressed audio file format developed by the Moving Picture Experts Group (MPEG). A typical MP3 file sounds similar to the original recording but requires significantly less disk space. The MP3 file format has been the standard for music files for quite some time. A typical MP3 file is usually about 1/11th the size of the original audio file.

An MP4 file is an audio-video file. A file with the MP4 file extension is an abbreviation for a MPEG-4 video file, which is a compressed file format that can contain not only video but also audio and subtitles. An MP4 file is a container format. This means that instead of storing the code for the file, it stores the data. One big benefit of this difference is that an MP4 file can be streamed online.

Now that we know what are MP3 and MP4 files and the difference between them, let’s look at the ways in which you can convert your MP3 file to an MP4 file.
