Podcast Cover Maker

Design for the thumbnail, not the canvas

Here's the uncomfortable truth about podcast cover design: almost nobody will ever see your cover at 3000×3000. They'll see it at roughly 55 pixels wide in a podcast app's browse list, competing with a dozen other tiny squares. Covers designed at full size — delicate type, detailed illustrations, clever negative space — collapse into gray mush at thumbnail scale. The covers that win are almost embarrassingly simple: three words or fewer, one bold typeface, two high-contrast colors, and a single visual idea. This tool's 55px legibility preview exists to enforce that discipline. If you can't read your title in the tiny preview, no amount of full-size polish will save it — simplify until you can.

The technical spec, demystified

Apple Podcasts — whose spec every other directory effectively follows — requires square artwork between 1400×1400 and 3000×3000 pixels, in RGB color space. Spotify, Overcast, Pocket Casts and YouTube Music all accept the same file. Exporting at the full 3000×3000 maximum is the right call: it looks sharpest on retina displays and large screens, and it future-proofs you if directories raise their minimums. PNG is preferred over JPG for covers with text and flat color, because JPG compression artifacts visibly degrade sharp edges. This tool exports exactly that: a 3000×3000 square PNG in RGB, generated from vector-sharp canvas rendering so type stays crisp at every size.

Typography rules for tiny squares

Type does 90% of the work on a podcast cover, so choose like it matters. Use one typeface — two at most — and favor bold weights: at 55px, regular weights disappear. Keep titles to 1–4 words; long titles force small type, which is the most common amateur tell in podcast directories. Contrast is non-negotiable: light type on dark grounds or dark type on light grounds, and test both against the app's own background (Apple's list is white, Spotify's is near-black). Avoid placing critical text over busy photo areas — if you upload a background photo, the tool applies a dark overlay automatically, but picking a simple, dark, low-detail photo still works better. Letterspaced small caps can look premium at full size but often blur at thumbnail scale; save them for the author line, never the title.

Color, branding and standing out in the feed

Scroll any podcast category and you'll see the same palette repeated: dark blue gradients, black and red, corporate teal. Standing out doesn't require clashing colors — it requires owning one. Pick a signature color and use it boldly and consistently, because listeners navigate feeds by color blob long before they read titles. Duotone treatments (one color, one dark) photograph well at every size and look intentional rather than default. If your show has existing branding, match the cover to it exactly — the cover, the social avatars and the website should read as one system. And resist the urge to put your release schedule, episode numbers or taglines on the cover: directories display that metadata as text next to the art, so baking it into the image just wastes precious thumbnail pixels.
