Audio Metadata Remover

Where do audio files keep their tags?

Every format has its own tag system, but they all hold the same kinds of thing: text fields, pictures and private data that apps add without asking. The audio sits in a separate part of the file, which is what makes clean removal possible.

What can audio tags give away?

• Names. Artist, composer, "encoded by" and copyright fields are often filled in automatically with your name, your studio or a collaborator’s.
• Notes and lyrics. Comments like "mix 4 — client wants the bridge cut" and unreleased lyrics travel with every copy.
• Software and private frames. The encoder or DAW name and version, sometimes its exact settings, and PRIV frames — opaque blobs left by players and stores, such as Windows Media Player’s library IDs.
• AI-generator tags. Tracks from AI music and voice services can carry the service’s name, a link back to the generation page or your account name. The tags go; an inaudible watermark mixed into the sound does not.

Should you keep the cover art?

The Keep cover art toggle decides. Artwork is a complete JPEG or PNG inside the file, often tens or hundreds of kilobytes, and it is kept byte for byte — including any camera data inside that picture. If the cover is a phone photo, or the file must be completely clean, leave it out and players will show a generic icon. For a podcast or a release where the artwork matters, keep it.

Does stripping tags change the sound?

No. The file is remuxed with a stream copy: the encoded audio frames go into the new file exactly as they were, and only the container and its tags are rebuilt. Bitrate, sample rate, channels and length are unchanged, with no generation loss however often you do it. The file usually shrinks a little — by the tags, any padding a tagger reserved and the artwork if you drop it.

Is my audio uploaded?

No. Unreleased tracks, interviews and voice memos are read and rebuilt inside your browser by ffmpeg compiled to WebAssembly; confirm it in DevTools → Network, where no request carries your file. Check the file name too: it is not metadata, and voice-memo apps often name recordings after a place.
