What size should my podcast cover art be?

Podcast cover art needs to be square. For the best results in Apple Podcasts, Spotify and other apps, upload a 3000 x 3000 pixel image.

What you can upload to Transistor

• Shape: square
• Recommended size: 3000 x 3000 pixels
• File type: JPG, PNG or WebP
• File size: up to 15 MB

You don't need to shrink or convert your image first. We automatically create the version podcast apps use: a 1400 x 1400 pixel JPG, kept small enough for every app.

Episode artwork follows the same rules.
