Your cover art is the first thing people see. Get the specs right or risk rejection.
Almost every DSP requires the same baseline:
PNG is preferred if you want lossless quality; JPEG at maximum quality (100%) is also accepted. Avoid progressive JPEG — use baseline/standard scan order.
Cover art is displayed at many sizes — from a 64px thumbnail on a playlist to a 1000px full-screen on a smart TV. Test yours at small sizes using BeatCheck's DSP preview tool on the release page.
