Comprehensive Guide & Technical Mechanics

About Audio ID3 Tag & Metadata Editor — Free Online Tool

Audio ID3 Tag & Metadata Editor writes title, artist, album, album artist, genre, year, track, composer and comment into audio files, and can attach a cover image, without touching the sound.

The audio stream is copied rather than decoded and re-encoded, so the sound comes back byte for byte identical and the job finishes about as fast as the file can be written. MP3 files get an ID3v2.3 block and an ID3v1 one as well, because some car head units and older players still read only the old tag; a cover image is attached as a picture stream marked as attached art. The batch writes one set of values to every file at once, which suits a whole album but makes it the wrong tool for per-track titles, and a field left blank is skipped rather than written empty — so it cannot be used to clear a tag that is already in the file.

What you type and the image you attach stay inside the page, and nothing is looked up online: no filename is sent to a music database and no artwork is fetched from one. The rewritten files are handed back as downloads.

Giving a ripped album consistent artist and album fields, adding cover art so a phone shows something other than a grey square, fixing the year and genre on files that arrived with neither, and tagging your own recordings before they go into a library.
