Drop in one piece of key art and get every capsule size Steam asks for. Then check your assets against Valve's specs, tighten your store copy, price every region and work through a 25-step launch checklist. It all runs in your browser.
Each store and library slot has its own size and ratio, and the rules live across a dozen Steamworks doc pages. Get one wrong and you find out after upload, or when your page looks broken in the library.

No. Every tool runs in your browser using the Canvas API. Images are stored only on your machine, in your browser's local storage, and never sent to a server. That's also why there's no sign-up.
Yes, on purpose. The three capsule sizes every page needs, full validation, copy checks, the whole checklist and the revenue estimator are free. Pro adds the remaining sizes, exports and the store page preview, and removes ads.
No. Free tools work straight away. Pro is unlocked with a license key from a one-time purchase.
No. ShipIndie is an independent tool and isn't affiliated with Valve. The specs it checks come from the public Steamworks documentation, and the guides explain the parts that documentation glosses over.
Purchases run through Lemon Squeezy as merchant of record. If Pro doesn't work for you, reply to your purchase receipt and we'll sort it out.
