Audio Metadata Editor

What is an audio metadata editor?

An audio metadata editor is a tool for reading and changing the tag information embedded inside an audio file, things like the song title, artist, album, and cover art, separately from the audio data itself. This audio metadata editor reads whatever tags a file already has, shows them prefilled in a form, and lets you add, correct, or remove them before you save.

Because the audio itself is not decoded or re-encoded when you save (FLAC is written natively; MP3, M4A, OGG, and WAV go through an FFmpeg stream copy), only the tag data changes. The sound of the file is exactly what it was before you opened it.

ID3v2, Vorbis comments, and MP4 atoms: why tags work differently by format

Different audio formats store tags in genuinely different ways under the hood, which is why an MP3 tag editor and a FLAC tag editor are not quite the same problem. MP3 files use ID3v2, a frame-based tag system where each field, title, artist, and so on, is its own labeled chunk of data appended to the file.

FLAC and OGG files use Vorbis comments instead, a simpler list of plain key-and-value pairs. M4A and AAC files store tags in MP4 atoms, sometimes called iTunes-style tags, which are part of the MP4 container structure itself rather than an add-on block. This editor handles all three transparently, so you do not need to know which one applies. You just edit the fields.

Which metadata fields can you edit?

You can edit title, artist, album, album artist, year, track number, genre, and comment, along with cover art where the format allows it. These cover the fields most players and libraries actually read when organizing your music.

Adding cover art to MP3, M4A, and FLAC files

You can add or replace cover art on MP3, M4A, and FLAC files directly in this editor, which covers most everyday listening formats. OGG and WAV are not supported for cover art here; if your file is a FLAC and you specifically want a dedicated artwork workflow with picture types and extraction, the FLAC cover art tool covers that in more depth.

Adding art does not touch the audio: FLAC art is written to the file's own picture data, and MP3 and M4A cover art is added the same way the rest of the tags are, without decoding or re-encoding the audio.

Clearing all tags for privacy

Audio files can quietly carry more than a title and artist. Ripping and encoding software sometimes writes an encoder name, a comment field, or other identifying notes into a file without you noticing. The clear all tags option removes everything in one action, which is a fast way to strip that kind of metadata before you share a file, rather than deleting fields one at a time.

This is separate from removing cover art specifically; clearing all tags wipes the text fields and artwork together, so use it when you want a genuinely clean file rather than a selective edit.

What to expect by format

Not every format handles metadata the same way once it leaves this tool. FLAC's Vorbis comments and MP3's ID3v2 tags are read reliably by nearly every player and music library. WAV can technically carry tag data, but support for reading it back is inconsistent across players and operating systems, so do not rely on WAV metadata surviving every app you might use.

If long-term compatibility of your tags matters, MP3 or FLAC are the safer bets over WAV or OGG for metadata specifically, independent of which format you'd choose for the audio quality itself.
