How can I improve the quality of the cover in the final ePub file?
To stop it from shrinking in Calibre go to Preferences - Tweak - The maximum width and height for covers saved in the calibre library change this tweak so maximum cover size is larger than the cover you are attempting to use. I have mine set to maximum_cover_size = (3000, 4000)
