About podcast cover art
Podcast covers must be square to work in apps like iTunes, Stitcher, and Acast and must be sized between 1400x1400 and 3000x3000 pixels. Your image should also be a perfect square or else you will not be able to save the cover art.
If you do not choose episode cover art, the cover art for your show will be used by default. Episode cover art is not required, and in fact, some apps (like Apple Podcasts) do not support or display episode cover art at all.
When will my new cover art show up on a podcast app? There is often lag time between when you post your new cover art on Acast and when you see the change on iTunes and other platforms. Though the change is immediate on Acast, it may take a few days for other platforms to process.
