AUDIO METADATA REMOVER

Remove metadata from audio files

Audio files can include artist and album names, comments, lyrics, recording dates, software, artwork and IDs. KillMetadata removes supported tags locally while keeping the audio essence unchanged.

THE CLEANING PLAN

Remove what exposes you. Keep what makes the file work.

Every field is shown before the rewrite and classified by action and coverage.

Remove
  • Artist, album, title and composer tags
  • Comments, lyrics, copyright and custom text
  • Recording dates and software identifiers
  • Embedded artwork and cover images
  • ID3, APE, Vorbis-style and container metadata where supported
Preserve
  • MPEG frames or encoded audio samples
  • Codec headers and stream information
  • Gapless playback values
  • Channel layout, sample rate and timing
Outside this guarantee
  • Names or information spoken in the recording
  • Audio fingerprints and acoustic recognition
  • DRM-protected content
  • Player-library records stored outside the file

WHY THE ENGINE MATTERS

Tags are removed around the audio stream

MP3 tags sit before or after MPEG frames; FLAC uses metadata blocks; WAV stores RIFF chunks; M4A uses BMFF boxes; Ogg Vorbis, Opus and FLAC use bounded comment packets. Each handler removes supported descriptive carriers while retaining codec-critical data.

Artwork is removed by the privacy-default profile. Gapless and codec headers are preserved because deleting them can introduce playback gaps or make a file unreadable.

BEFORE YOU SHARE

A four-step privacy check.

Metadata cleaning is one part of a safe sharing workflow.

  1. 01Review artist, date, comment, lyric and artwork fields
  2. 02Confirm gapless and codec data are preserved
  3. 03Create the clean copy
  4. 04Play the beginning, middle, end and track transition

QUESTIONS, ANSWERED

Know the boundary before you clean.

No vague “100% clean” claim.

Are my files uploaded?

No. The cleaner runs in your browser, has no upload endpoint, and only enables the file picker after its processor assets are available locally.

Is the original file changed?

No. KillMetadata reads the original and creates a separately named cleaned copy. It never overwrites the source file.

Does cleaning change the audio quality?

Supported handlers copy encoded frames or samples rather than re-encoding them, so metadata cleanup does not introduce codec loss.

Is album artwork removed?

Yes when it is stored as a supported metadata carrier. Artwork and thumbnails are part of the privacy-default removal profile.

Runs locally in your browserReady to inspect your file?

The picker opens only after offline protection is active.
