TagRex review
A free, open-source batch tag editor for detailed control of personal music collections.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TagRex is a free, open-source desktop audio tag editor for Windows, macOS and Linux. It is aimed at solo users and small teams organizing personal music collections who want direct control over metadata, filenames, artwork and exports. The spreadsheet-style tag table supports configurable columns, filtering and sorting, while a built-in preview player offers gapless playback. TagRex is focused on editing and organization rather than fully automatic tagging or complete library management.
The published offering is free, with no paid tiers described. Its strongest workflow is batch editing: users can create change plans, set an apply scope for each row and rely on a transactional undo journal. Filename masks rename files and reorganize folders, while reverse masks read tags from filenames. Text transformation presets handle case conversion, replacement and transliteration. Duplicate scans, cover-art fetching and resizing, and M3U, CUE, CSV, HTML and XML exports extend the organization toolkit. Multiple tag block types and support for 12 audio formats add flexibility for mixed collections.
Metadata lookup connects to Discogs, MusicBrainz, Beatport, Bandcamp and Soundeo, giving the desktop editor several catalog sources within its workflow. The cross-platform footprint suits users who move between Windows, macOS and Linux, although macOS downloads are Apple-Silicon only and Intel Macs are not built. TagRex is a strong fit for people who prefer deliberate, reversible batch control and local file organization. Choose another tool if you need mobile or browser access, fully automatic library management, or support beyond the documented desktop and documentation-based model.
