A focused native macOS editor for MP3 metadata, artwork and lyrics.
Wuner was built as an alternative to MP3 metadata editors centered around batch workflows, large libraries, and dense table-based interfaces. It takes a deliberately simpler approach: open one MP3, fix its metadata, artwork and lyrics, save it safely, and move on.
- Edit common MP3 metadata
- View and edit embedded lyrics
- Replace, remove, or drag-and-drop album artwork
- Open MP3 files from Finder, the Dock, drag and drop, or
⌘O - Native macOS interface and keyboard shortcuts
- Inline metadata validation
- Unsaved-change protection
- Safe file replacement when saving
Open an MP3 by dragging it into Wuner, clicking the drop area, pressing ⌘O, choosing File → Open…, using File → Open Recent, choosing Open With → Wuner in Finder, or dropping it onto Wuner in the Dock.
Edit the metadata and press ⌘S to save.
Wuner warns before opening or closing a track with unsaved changes.
| Shortcut | Action |
|---|---|
⌘O |
Open MP3 |
⌘S |
Save |
⌘⌫ |
Close current track |
Wuner writes a fresh ID3v2.3 tag while preserving the MP3 audio data.
Changes are written to a temporary file and verified before the original file is replaced. If saving fails, the original MP3 is left untouched.
Wuner reads and writes:
