UPDATED: Select Files and Convert v1.2
For macOS 10.15 and later only. This script applet will convert a selection of files in the Finder using an encoder from the Music app. Converted files can be saved to a user-selected location and will be removed from the Music app after the process...as though it "never saw them". Includes options to create a "Converted" subfolder and delete source files. (I use this as a dropless alternative to Drop A Few My Way.)
Latest version:
- Additional accommodations for macOS 11 Big Sur
