We all know that MP3 files are used to store and view audio, whereas MP4 files are used to store and view the video. Both the MP4 and MP3 file formats have the same lineage – they both come from the Moving Picture Experts Group (MPEG) format of file compression. You can convert MP4 to MP3 by stripping away the audio contents.

Sometimes, it's necessary to convert an MP3 file into MP4 because of device compatibility. A device that supports playing MP4 files can sometimes, but not always, play an MP3 file, but a device that only plays an MP3 can never play an MP4. Regardless of what the reason is, if you don't know how to convert MP3 to MP4, find the best MP3 to MP4 converter here.
