Mp3ID3Tagger: A macOS application to edit the ID3 tag of your mp3 files

A macOS application to edit the ID3 tag of your mp3 files. You can download the application from this link.


Mp3ID3Tagger support the following ID3 tag versions: 2.2, 2.3 and 2.4. It will let you modify the following information inside the ID3 tag of you mp3 file:

  • version of the tag
  • title
  • artist
  • album
  • year
  • track position
  • genre
  • attached picture set as Front cover


The application is entirely written in swift. It relays on a swift library I developed to edit ID3 tags of mp3 files: ID3TagEditor. The application has been built using RxSwift and RxCocoa as an experiment to apply the reactive programming paradigm in a real project. The architectural pattern used to build the application is the Model-View-ViewModel.
Below you can find some screenshots of the app:
