Free Tool
Steam Capsule Analyzer
Free tool that renders your Steam capsules at every size players actually see: header, library, micro-trailer, big picture, and the discovery queue. Spot the gaps that cost you wishlists.
What it does
Steam uses six different capsule sizes across discovery, library, search, and the home page. A title that looks crisp in the header can disappear at the small-capsule size, which is the size 80% of Steam shoppers actually scroll past.
The Steam Capsule Analyzer audits all of them at once:
- All six capsule sizes rendered side-by-side, exactly as Steam shows them.
- Title legibility check at the smallest sizes, the ones that actually decide click-through.
- Reference examples from top-performing Steam launches so you can benchmark yours.
- Side-by-side comparison between versions, so you can A/B variants before you push live.
Why it matters for your launch
Steam wishlist conversion has fallen from ~20% in 2018 to 5–10% in 2026. The studios still hitting double-digit conversion treat their capsule like a paid ad and optimise it for the click. Auditing every render size is one of the cheapest pre-launch wins there is.
