For macOS 10.12 and later only. This applet will examine the artwork of each selected track (or tracks in the selected playlist) and if greater than a user-set resolution (n x n pixels) will downscale the image to that resolution. Artwork already at the set resolution or smaller will not be affected. Includes options to pad image to make square, preserve extant track artworks, adjust preview proportionally and export displayed artwork to disk.
Also see Tracks Without Embedded Artwork.
