Podcast Cover Art Generator with AI (3000×3000)
Generate podcast cover art at the Apple- and Spotify-required 3000×3000 square in your browser. AI-powered, free, and readable at the tiny sizes players actually show.
Apple Podcasts and Spotify both want a 3000×3000 RGB square, JPG or PNG, under a few megabytes. Miss the spec and your show either won't get accepted or gets a fuzzy upscale in the directory. This guide covers what actually works at thumbnail scale — not what looks good in Figma at 100%.
The 3000×3000 rules
- RGB color, not CMYK. Convert first if your source came from print software.
- Keep the title inside a 2400×2400 safe area — some players crop the corners for rounded thumbnails.
- One or two words max at the size players display it (as small as 55×55 in list views).
Generate a cover
- Choose the podcast 3000×3000 preset in the AI thumbnail generator.
- Upload reference art — your existing logo, a headshot, or mood images.
- Prompt with genre + tone: "cinematic true-crime cover, moody blues, single strong headline."
- Refine the title and subtitle in the editor layer, then export as JPG.
