MetadataMaster review
A capable free tag editor for Apple devices, with strong batch and MusicBrainz tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MetadataMaster is a native audio metadata editor for macOS and iPadOS, aimed at people organizing personal music libraries on Apple devices. It supports batch editing of selected audio files, MusicBrainz-assisted tagging and release matching, embedded artwork management, filename and metadata conversion, track and disc renumbering, and raw TagLib property-map editing. The software handles lossless, lossy and DSD containers, works locally by default, and is distributed as free open-source software.
There is one free offering with no premium tier or subscription. Its ecosystem connections focus on music metadata and artwork: MusicBrainz supplies tagging and release matching, while iTunes artwork search supports cover-art discovery. Network access is reserved for explicitly requested lookups, which suits users who want local library work with optional online enrichment. Watched folders add automatic processing on macOS, extending the batch workflow beyond one-time edits.
The standout depth is its combination of token-based filename-to-metadata and metadata-to-filename conversion with renumbering and raw property-map access. That gives detail-oriented users control over both visible tags and file organization, while artwork preview, replacement and clearing cover common library-maintenance tasks. MetadataMaster is a strong fit for solo users and small collections centered on macOS or iPadOS who want a no-cost, open-source editor. Choose another tool if you need platforms beyond Apple devices, support channels beyond documentation, or watched-folder processing on iPadOS.
