Ko-fi covers that hold a creator identity across stickers, commissions, and digital downloads

The Ko-fi shop cover playbook, in one preset

Ko-fi's shop image specification is documented per slot in the platform's Help Center, and the slots that matter most for cover-driven conversion are the shop product cover, the product gallery images, the commission tier graphic, the membership tier reward image, and the creator-page banner and avatar. The product cover is the single primary image that renders on the storefront card and the product page hero — Ko-fi documents 600×600 px as the minimum and high-resolution / square as the best-practice, with 1200×1200 the working sweet spot and 2000×2000 the upload target for premium creators selling original artwork or large digital downloads. The aspect ratio is 1:1 square strongly preferred for shop products, commission tiers, and membership tiers; the cover banner on the creator-page header is a separate 4:1 wide-strip at 1600×400, and the profile picture is 1024×1024 (renders ~80×80 in nav and ~200×200 on the page header). JPEG and PNG are both accepted, with PNG required when the cover has transparent regions or sticker-style artwork on transparent backgrounds; the per-image cap is 5 MB. Up to 6 additional product gallery images per shop product, all at the same 1:1 square spec — and product types like original artwork, commission examples, and digital downloads lean heavily on the gallery for the supporter's pre-purchase confidence.

The design rule that drives Ko-fi sales isn't technical — it's catalogue consistency across shop, commissions, and tier graphics. A creator with 5-15 shop products and 3-5 commission tiers needs every cover to share a colour palette, an illustration style, and a composition formula because that consistency reads as a developed creative practice that supporters will trust their tip / commission / shop purchase with. Ko-fi's content policy is permissive but specific. Adult / NSFW creators require an opt-in adult-flag on their creator page, which constrains the cover-image surface to non-explicit imagery — the storefront card surface is age-class-blind, so even adult-flagged creators show a SFW cover on the public storefront. Copyrighted character art and brand logos used commercially without licence (Marvel, Disney, Nintendo, Pokémon, Sanrio) trigger DMCA takedowns from rightsholders. Unlicensed stock photos from Getty / Adobe / Shutterstock trigger DMCA from the stock library. Watermarks are allowed and encouraged on commission-example showcases. Text overlays — sticker pack titles, commission-tier names, pricing tags on Procreate brush packs, sold-out badges on limited-run prints — are all common and accepted. The preset preserves whatever is in the source upload; the licensing decision is the creator's responsibility.

Why a cohesive shop identity drives more Ko-fi commission requests

Ko-fi's funnel is short — public creator page or shop link to checkout — and the cover image is the single conversion lever between browse and product page on the storefront card. Creators with a cohesive shop identity (palette, type, composition formula consistent across stickers, commissions, original artwork, and digital downloads) outperform creators with mixed aesthetics on commission requests and tip-jar contributions, because the consistency reads as a sustained creative practice the supporter is investing in for months. Sticker shop sellers see the strongest cover-image conversion lift from the multi-sticker grid composition with consistent spacing and brand-background fill, because the cover stops reading as a screenshot from the photographer's table. Photographers and illustrators selling packshot products see the studio-backdrop removal pay off because the cover stops standing apart from the rest of the catalogue. Commission artists see the showcase-tier graphic convert higher when the past-commission grid is composed at the 1200×1200 spec with consistent spacing, rather than a casual portfolio screenshot. Running every cover and gallery image through the preset before the next shop product launch is the cheapest commission-request lift available without changing the underlying art.
