Strip Audio Metadata
Pick an audio file and remove tags, chapters, and cover art locally in your browser — the audio is stream-copied, not re-encoded.
Remove Audio Tags Without Re-Encoding
Drop privacy-sensitive tags from MP3, FLAC, OGG, M4A, WAV, and other audio files directly in your browser. The tool asks ffmpeg to stream-copy the audio, remove global and stream metadata, drop chapters, and remove embedded cover art by default. Nothing is uploaded to a server.
Worked Example
Choose song.mp3, leave Cover art set to remove, and download the cleaned
MP3. The audio frames are copied through unchanged while ID3 tags, comments,
chapter markers, encoder metadata, and the album-art stream are removed. If you
want to keep the picture but remove text tags, set Cover art to keep.
Command-line equivalent:
gizza tool audio-metadata-stripper 'url=https://example.com/song.mp3' 'cover_art=remove' --out song-clean.mp3
Limits and Edge Cases
- The browser page processes the file locally with ffmpeg.wasm; very large audio files may exceed memory limits.
- The tool removes metadata but does not edit or rewrite specific fields. Use a tag editor if you want to change artist/album/title values.
- Stream-copy preserves the existing codec/container. If the input container is unusual or damaged, ffmpeg may reject it rather than re-encode it.
FAQ
Will this change the sound quality?
No. The ffmpeg plan uses stream copy (-c copy), so the encoded audio packets are
copied into a clean container instead of being decoded and encoded again.
Does it remove album artwork?
Yes by default. Set Cover art to keep if you want the embedded picture to
remain while text tags and chapters are stripped.
Which metadata is removed?
The tool drops container and stream tags such as ID3, Vorbis comments, RIFF/ASF INFO fields, chapter markers, and ffmpeg muxer metadata where the container allows it.
Is my audio uploaded?
No. The standalone page runs ffmpeg in WebAssembly inside your browser tab. The CLI/chat tool resolves its own provided URL or attachment reference, but the page does not upload your file to gizza.ai.
