Download Kid3 Tag Editor – Free Audio Tagging Tool for macOS
Overview
Kid3 Tag Editor is a powerful, free file‑management utility built specifically for macOS users who need to keep their music libraries tidy and searchable. In today’s streaming‑first world, many audiophiles still cherish locally stored collections, and the quality of those collections hinges on accurate metadata. Kid3 steps in as a dedicated tag‑editing solution that supports a broad range of audio formats—from MP3 and FLAC to OGG and WMA—allowing you to edit ID3v1, ID3v2, and APE tags with just a few clicks.
The application shines because it combines a clean, intuitive interface with batch‑processing capabilities, meaning you can edit hundreds of files in seconds rather than laboriously updating each track individually. Whether you’re a casual listener looking to fix a few misnamed songs or a professional DJ curating an extensive library, Kid3 offers the flexibility and precision you need without any hidden fees or intrusive ads. Its open‑source roots ensure that updates are frequent, secure, and driven by a community that values privacy and reliability.
By providing import and export functions for tag data, Kid3 also lets you back up your metadata or migrate it between different music management tools, making it an essential companion for anyone serious about audio organization on a Mac.
Core Features
- Comprehensive Tag Support: Full read/write access to ID3v1, ID3v2 (including Unicode), and APE tags, ensuring compatibility with virtually every audio file you own.

- Import/Export Tag Data: Easily import tag information from CSV or export current tags to CSV, JSON, or plain text for backup or bulk editing outside the app.

- Customizable Views: Choose between list view, tree view, or cover‑art preview to match your workflow preferences.
Installation, Usage & Compatibility
Installing Kid3 on a Mac is deliberately simple. Visit the official Kid3 website, click the “Download for macOS” button, and you’ll receive a signed DMG file. After opening the DMG, drag the Kid3 icon into your Applications folder—standard macOS practice that ensures the app receives the proper permissions. The first launch may prompt Gatekeeper to verify the software; because Kid3 is notarized, you can safely approve it and continue.
Once installed, launching Kid3 presents you with a clean workspace. To tag a single file, click the Open button, navigate to your music file, and the tag fields populate automatically. Edit any field—title, artist, album, track number, genre, or cover art—then hit Save. For batch operations, select a folder from the left pane, choose Select All or manually tick the files you wish to edit, fill in the desired fields, and click Apply to Selected Files. The changes propagate instantly, and you can undo any edit within the session via the Undo command.
Kid3 is built exclusively for macOS (10.12 Sierra and later). While the core codebase also runs on Windows and Linux, the macOS build includes native UI elements that blend seamlessly with the Apple ecosystem. Users on other platforms can still benefit from Kid3 by downloading the appropriate version from the same website, but the features described here focus on the macOS experience.
Updating Kid3 is equally straightforward. The app checks for new releases on startup and notifies you if a newer version is available. Clicking the notification redirects you to the download page where you can replace the old DMG with the latest one. Because the software is open source, you also have the option to compile the latest code yourself if you prefer a custom build.

Is Kid3 completely free or are there hidden costs?
Kid3 is 100 % free. There are no paid tiers, no subscription fees, and no in‑app purchases. All features, including batch editing and online lookups, are available to every user.
