TuneTag

TuneTag is a native macOS application written in Swift that provides a focused environment for editing ID3 tags and other metadata in audio files. Users can drag individual files or entire folders into the window, where supported formats are listed and their metadata become immediately editable. Changes are written directly to the files, ensuring compatibility with modern operating systems and audio devices.

The tool emphasizes batch operations: track numbers can be incremented automatically, file names and track titles can be renamed using custom templates, and cover art can be exported or replaced via a drag‑and‑drop interface. Quick Look integration allows users to preview songs without leaving the app, and dragging files out of TuneTag creates copies in the Finder.

Designed for speed and simplicity, TuneTag launches quickly, offers a minimal modern UI, and handles all editing tasks without the broader library management features of the default Music app. It targets macOS 14+ users who need a lightweight, dedicated solution for managing audio metadata.
