About This Tool
This MP3 tag editor runs entirely in your browser using JavaScript. Your files are never uploaded to any server — the ID3 reading and writing happens locally on your device using a custom-built ID3 parser and the browser-id3-writer library.
Supported fields: Title, Artist, Album, Year, Genre, Track Number, Composer, and Comment. Multiple artists or composers can be separated by commas.
What you can do with tagged MP3s
- Keep your music library tidy — correct titles and artists show up properly in any player.
- Add cover art so your songs look right in playlists and on social media.
- Prepare files for sharing — clean up metadata before sending a track to someone.
- Fix downloaded Suno files — after saving songs, tag them with the right details.
