Metadata Changer

Metadata Changer is an Android utility to view and edit file metadata safely. It provides tools to modify image EXIF, audio ID3 tags and file timestamps with a simple interface suitable for casual and advanced users, and it creates automatic backups before changes so you can restore original values if needed.

Features

Metadata Changer can edit EXIF fields such as camera model, date taken and location for supported image files. The app also supports editing ID3 tags for audio files, including title, artist, album and genre. You can apply changes to multiple files at once using batch edit mode and change file creation and modification timestamps without altering the underlying media. The editor shows a preview of changes and keeps a backup history so previous metadata can be restored. Import and export options let you reuse or apply metadata in common formats, and the app works offline using standard Android storage permissions for file access.

How to use

Grant the app access to the folders or files you want to edit, then select one or more files to review existing metadata in the editor view. Modify fields as needed and use batch mode for multiple items, then save your changes. Review the automatic backup entry if you need to revert any edits. For straightforward editing of many files, Metadata Changer's batch and preview features help reduce mistakes.

Notes

Metadata changes update file metadata only and do not alter the underlying media content. Some apps or services may overwrite metadata when they process files, so keep backups if edits are important. Respect privacy and copyright when editing or sharing files with modified metadata. The app requires permission to access storage and will request only the permissions necessary for its functions.
