Frequently asked questions
What ID3 version should I use — v2.3 or v2.4?+
ID3 v2.3 has broader compatibility — it is supported by iTunes, Windows Media Player, and most embedded players in cars and hardware devices. ID3 v2.4 adds UTF-8 encoding support (better for non-Latin characters) and is supported by modern software. For maximum compatibility, use v2.3 unless you need v2.4-specific features.
Why is my album artwork not showing in some players?+
Album artwork must be embedded as an APIC (Attached Picture) frame in ID3 v2.3+. Some older players only read artwork from the filesystem (as folder.jpg or cover.jpg in the same directory). Embedded artwork should show in iTunes, Apple Music, Spotify, and most modern players. If artwork shows in one app but not another, the app may only read filesystem artwork.
Can I edit tags on FLAC or M4A files?+
FLAC uses Vorbis comment tags (not ID3), and M4A files use iTunes/MP4 metadata atoms. JAD's ID3 editor is specifically for MP3 files. For FLAC and M4A tag editing, use dedicated tools like Mp3tag (Windows), Kid3, or MusicBrainz Picard, which support multiple tag formats.
