FLACDrop

FLACDrop is a lightweight macOS menu bar app that watches folders and automatically converts FLAC files to MP3.

Features

• Watches selected folders for new FLAC files.
• Automatically converts FLAC to MP3 in the background.
• Preserves metadata during conversion.
• Offers configurable quality presets.
• Sends macOS notifications when conversions finish or fail.
• Supports drag-and-drop for quick manual imports.
• Keeps a conversion history so you can review recent activity.

Requirements

• macOS 26
• ffmpeg installed via Homebrew

Installation

1. Clone the repo.
2. Install ffmpeg:

brew install ffmpeg

3. Open the project in Xcode.
4. Build and run the app.

Usage

FLACDrop runs as a menu bar app, so once it launches you interact with it from the menu bar instead of a normal dock app window.

Use the popover to configure watched folders, adjust conversion quality, review history, and drag files in for one-off imports. When new FLAC files appear in a watched folder, FLACDrop processes them automatically and posts a macOS notification when it’s done.
