Reference
What are ID3 tags?
ID3 tags are metadata blocks embedded in MP3 files. ID3v1 is a fixed 128-byte tag at the end of the file with title, artist, album, year, comment, and genre. ID3v2 sits at the start, has flexible-length frames, supports Unicode, and can contain cover art (APIC frame). The tool reads both formats locally — files never leave your browser.
ID3v2 frames
ID3v2 stores metadata as named frames (TIT2 = title, TPE1 = artist, APIC = cover art, etc.). The tool decodes the most common frames and shows the rest in the raw frames list.
