Steam Image Resizer

Steam capsule art comes in three different sizes and Valve doesn't make that obvious. This tool resizes your artwork to the header, small, and main capsule dimensions instantly.

Designing Capsule Art That Works

  • Genre conventions in capsule design

    Indie narrative games often lead with a single character silhouette against a moody color; action games tend toward busier scene composition. Matching genre convention helps browsing players recognize your category at a glance.

  • Capsule art and wishlist conversion

    Most players see the small capsule first, in wishlist and search rows, before reaching your store page. A capsule that reads genre and mood in under a second matters more here than detail that only holds up at full size.

  • Character art vs. environment shots

    A single strong character portrait often outperforms a busy scene at small capsule size, since a face reads faster than an environment once scaled down to 120x45px.

  • Consistency across your three capsules

    Reusing the same character pose or color palette across header, small, and main capsule, even with different crops, makes your store page feel cohesive rather than three unrelated pieces of art.

  • Text on capsule art

    Steam's own guidelines discourage heavy taglines on capsule art, since the store page already carries that text elsewhere - let the art alone communicate genre and tone.

  • When to update your capsule art

    A capsule refresh around a major update, sale, or anniversary can meaningfully lift visibility in Steam's algorithm-driven discovery surfaces - stale, years-old capsule art is easy for returning players to scroll past without registering.

Frequently asked questions

The header capsule (920 x 430) sits at the top of your store page. The small capsule (462 x 174) appears in search results, wishlists, and recommendation rows. The main capsule (1,232 x 706) shows up in larger placements like the Discovery Queue. Each serves a different part of the store, not interchangeable crops of one image.
The small capsule gets scaled down the most in practice - sometimes to as little as 120 x 45 pixels in dense lists. Text or logos that look fine at full size often become illegible at that reduced scale. Design and test the small capsule at roughly 25% size before finalizing it.
Technically yes, but it's not recommended. Steam doesn't auto-crop capsule art, so a single image resized across very different aspect ratios (the small capsule is much more elongated than the main capsule) often ends up with awkward cropping or empty space. Designing each size separately gives better results.
Valve doubled the resolution of all store capsules in a 2022 asset refresh for sharper display on high-resolution screens. Guides that still show the old numbers (like 460 x 215 for the header capsule) haven't been updated since that change.
JPG or PNG. PNG is generally the safer choice for capsule art with text or logos, since it avoids the compression artifacts JPG can introduce around sharp edges.
The small capsule. It appears across the most high-traffic surfaces (search, wishlists, recommendations) and gets scaled down the most, so it's the one most likely to break if designed as an afterthought.
