For macOS 10.10 and later only. Drag and drop audio files to this droplet to have iTunes convert them with an encoder selected on the fly, restoring iTunes' Preferences-set encoder afterwards. Converted files can be saved to either a single selected location or each source file's parent folder. The converted files/tracks are removed from iTunes, as though iTunes "never saw them".
