Everytime a listener searches for your podcast or your category, they see your podcast cover.

While you might have uploaded a crisp 3000 by 3000 pixels design when you created your podcast, your listener might be seeing it at 50 by 50 pixels depending on the podcast app and the page they are on.

Each podcast app has it's own size definitions and each page on these app has a slightly different way of displaying your podcast cover.

This is why PodcastCoverPreview.com exists.

This tool allows you to preview and check your podcast cover looks good at all the different sizes in the top podcast apps.
