M4A metadata viewer

Upload an M4A file and see every metadata tag stored inside — title, artist, album, cover art, and more.

iTunes-style tags, decoded

M4A metadata lives in MP4 atoms using the tagging scheme iTunes popularized: title, artist, album, artwork, and a tail of less obvious fields written by apps. The viewer parses and displays them all locally.

Frequently asked questions

Why do some M4A tags not show in my player?

Players read a subset of atoms and ignore the rest. The viewer shows everything present, including fields your player skips.

Do voice memos contain identifying metadata?

They can carry creation dates and app-written fields. Worth a look before sharing a recording; the metadata tools can edit or strip what you find.
