M4A Metadata Remover: Remove Tags and Cover Art
An M4A file keeps its tags, cover art, and technical identifiers inside the MP4 container. Files bought from a store can also carry the buyer's Apple ID and name. Choose a file, review every field, and download a cleaned copy whose audio is verified identical.

What happens locally
A focused cleaner, not a black box.
Erased in place, audio untouched
Metadata areas are zero-filled where they are, so the file size and every audio offset stay the same. The audio data is compared by SHA-256 with the original and the length and codec are checked again.
Private local processing
The file is read and rewritten inside your browser. It is never uploaded, and your original file is never changed.
Important limit
This removes metadata, not sound. Speech, music, and anything audible stay in the recording, and audio watermarks or fingerprints are not touched. Copy-protected files (.m4p), Apple Lossless (ALAC) and other non-AAC audio, fragmented or streaming MP4, and files with extra tracks such as chapters or text are not supported. Removing iTunes gapless data may add a tiny gap between tracks. Verification is structural; the result was not played back.
Questions & boundaries
Know exactly what the clean copy means.
File formats are messy. These answers describe the supported behavior of this version—not a promise that every trace everywhere has disappeared.
01How do I remove cover art from an M4A file?+
Choose the file on this page. The embedded cover appears in the list as Cover art. Keep it ticked, click Clean, and download the new copy. The audio is not touched.
02What metadata does it remove from M4A and M4B?+
The title, artist, album, album artist, composer, genre, comments, copyright, dates, lyrics, track and disc numbers, cover art, iTunes custom tags, store purchase details such as the Apple ID and owner name, encoder names, track handler names, creation and modification times, and padding areas.
03Does it re-encode or change the audio?+
No. Metadata is zero-filled in place, so the audio bytes do not move. After cleaning, the audio data is compared with the original by SHA-256, and the tracks and duration are checked again.
04Can a file I bought contain my name?+
It can. Store-bought M4A files often include the Apple ID used to buy them and the owner name. This tool lists them as separate fields so you can remove them before sharing the file.
05Is my file uploaded?+
No. The file is processed inside your browser. You can confirm this in the Network panel of your browser's developer tools.
06Which M4A files are not supported?+
Standard AAC files are supported. Files that use Apple Lossless (ALAC) or another non-AAC codec, copy-protected .m4p tracks, and files with extra tracks such as chapters are refused with an explanation instead of being changed. Convert ALAC to AAC first, or use a tool that supports it.
07What about audiobooks with chapters?+
M4B audiobooks that store chapters as a separate track are not supported by this version and are refused rather than risk breaking the chapters.
