Can I convert .3gp videos to .mp3 format?
Converting 3GPP Multimedia Files directly to MP3 Audio Files (.3gp to .mp3 conversion) is certainly possible and should be quite straightforward. It relates to users attempting to extract the audio track (MP3) from a 3GP video.
Use a media editing software or (online) conversion tool, such as Adapter or Freemake Video Converter, which allow users to import 3GP videos and save their extracted audio track in MP3 format.
