Label audio
Embed a Made Mark label into an MP3's ID3 tags or a WAV's INFO metadata — what podcast apps and players read. Your existing tags (title, artist, artwork) are kept; the label is added alongside them. Everything runs in your browser — your file never leaves your device.

In an MP3, the label is written as TXXX frames plus a comment; in a WAV, as a LIST/INFO comment chunk. Either way any player or tag editor can show it — verify with exiftool yourfile, or read it back on the verify page. For FLAC or AAC, embed via XMP — see Implement.
