About this tool

Audio metadata is the difference between a music library that is searchable and browsable and a folder full of "track01.mp3". Media players, phone libraries, and car stereos all display information from ID3 or equivalent tags — artist name in the album view, track title on the lock screen, cover art in the now-playing display. Missing or incorrect tags make content hard to navigate and unprofessional in any context where other people will see it.

The cover art matters more than it might seem. A 600×600 JPEG embedded in the file means the artwork travels with the audio wherever the file goes — transferred to a new device, shared with someone, imported into a new library. Relying on a streaming service to look up artwork means it disappears the moment the file is played offline or in a player without that lookup capability.

Questions

What are ID3 tags?
ID3 is the metadata standard for MP3 files, and a similar system exists for M4A (iTunes-style atoms) and FLAC (Vorbis comment). These tags store the track title, artist, album, year, genre, track number, and embedded cover art — the information your music player shows when playing a track. Without tags, everything appears as an untitled track from an unknown artist.
What image format should I use for cover art?
JPEG for photographs and complex artwork, PNG for graphics with transparency or solid colours. Most players display cover art at 300–500 px square; embedding a 3000 px image wastes file space. A 600×600 JPEG at reasonable quality is a good target — it looks fine at any display size and does not inflate the file noticeably.
Can I batch-tag multiple files at once?
This editor works on one file at a time because tags are typically different for each track. For large library management with consistent fields across many files (setting the same album name on a hundred tracks, for example) a dedicated library manager like MusicBrainz Picard is better suited.
