Understanding Audio Metadata & ID3 Tags

Discover how ID3 tags store song titles, artist names, album info, lyrics, and high-resolution cover art inside MP3 audio files.

Quick Summary

ID3 tags are data blocks embedded inside MP3 files containing track title, artist name, album, year, genre, and cover artwork.

Detailed Instructions

Metadata is 'data about data'—it tells media players what song is playing, who created it, and what album art to show.

ID3v1 was limited to 30 characters per field. ID3v2 supports variable-length text, Unicode international characters, and binary album artwork.

Use our built-in ID3 tag editor to fix incorrect song titles and add beautiful album covers in seconds.

Ensure album art images are square (1:1 aspect ratio) so they render cleanly on Apple CarPlay and Android Auto.

Can WAV files hold ID3 tags?

WAV files traditionally use RIFF INFO chunks, which have limited support in consumer players. MP3 has universal ID3 support.
