An MP3 converter is a very useful tool that is used to convert video files to audio formats. As is well known, most media sharing platforms do not have the feature for directly downloading shared audio or video to personal devices, even though it can be easily accomplished with images.

These online video converters can usually extract the audio of a video from a number of sources like YouTube, Facebook, Instagram, Vimeo, Dailymotion and so on. In any such converter, MP3 is usually the preferred format of output audio file. But other formats like M4A, AAC, OGG, WMA, FLAC , WAV, etc. should also be available to make the converter versatile.
