When it comes to filing formats, there is a large variety of them. While some of them can be opened on any device, using any software, several files are not as compatible as others.
And because of the incompatibility and other reasons like you not needing a large-high-quality WAV file and just wanting to listen to the track on your MP3 player, there are audio file converters. These converters can convert different types of audio files, for example, mp3 to ogg.
There are quite some software choices when it comes to audio file conversion. Some have multiple functions, and some are great when you need to convert just a few files and hence there is no reason you should waste your money, time, and computer space installing specialized software in that case.
