Audio Metadata Remover

Strip the tags from audio files. The remover shows what the file contains – title, artist, album, comments, encoder, recording software, cover art – and removes it all by copying the audio stream into a clean file. Nothing is re-encoded, so the sound is bit-for-bit identical. Optionally keep the cover art or chapters.

Audio Metadata Remover FAQ

What metadata do audio files contain?

Titles, artists, albums, track numbers, comments, cover images, the encoding software and sometimes the recording device, date and location for voice memos.

Will the audio quality change?

No. The audio data is copied unchanged.

Why is the file smaller?

Cover art can be several hundred kilobytes; removing it shrinks the file.

Which tags remain?

Technical container fields such as the file brand, which contain no personal information.

Why does the first run take longer?

Re-encoding uses FFmpeg compiled to WebAssembly (about 32 MB), which is downloaded once and then cached.

Is my file uploaded?

No. Everything runs in your browser.

Tags in audio files

Audio formats store descriptive information alongside the sound. MP3 files use ID3 tags, M4A files use MP4 metadata atoms, FLAC and OGG use Vorbis comments. Music libraries rely on these tags, but they also travel with every copy of a file – including comments, encoder names and, for voice recordings, sometimes dates and device information.

The remover rebuilds the file with FFmpeg, copying only the audio stream and mapping no metadata from the source. Bit-exact flags and an empty encoder field keep FFmpeg from adding its own name. For MP3 files, a clean ID3v2.3 header is written without the old ID3v1 tag at the end.

Cover art is technically a small image stream inside the file. Removing it is the default; if you want to keep the artwork but remove the text tags, untick the option and the image is copied unchanged.

Before and after, the file is read and its tags are counted, so you can see exactly what was removed.

If you want to replace tags rather than remove them – for example to correct a title or add your own artist name – use the Audio Tag Editor instead, which keeps the audio unchanged as well.
