CAPKIT - Steam Capsule Toolkit

CapKit - Steam Capsule Toolkit

Making store art for your game shouldn’t be a pain.

CapKit helps you turn a single artwork into every capsule and promo image your storefront needs, fast.

Drop in your background, add your logo, arrange everything once, and export perfectly sized assets for Steam and itch.io. No Photoshop. No resizing. No digging through documentation for dimensions.

Just build once, export everything.

                                                             

What it does

Choose your platform, pick the sizes you need, and generate.

CapKit includes built-in presets for Steam capsules, library art, screenshots, event banners, icons, and itch.io cover formats  all at the exact dimensions storefronts expect.

No guesswork.

                                                              

Features

• All the sizes, ready to go - Steam and itch.io presets built in, exported at exact pixel dimensions in one click.
• Per-format freedom - Want your logo centered on the Main Capsule but off to the side on the Header? Every capsule keeps its own layout, background, effects, and text.
• Real logo control - Rotate, tilt, curve, flip, and drag-corner perspective. Add glow or shadow with custom colors. Adjust opacity.
• Layers panel / Canva-style layer list. Click to select, reorder, hide per size — even with overlapping art.
• Smart alignment guides. Drag-snap to center and to other elements.

• Background effects : Blur, vignette, color grading, and stylized looks, combinable and adjustable per image, with brightness / saturation / contrast.

• Text that behaves : Add titles with font selection, curve, rotation, and free placement.
• Readability simulator : Preview how your capsules look at real store display sizes before you publish.
• Undo/redo, copy/paste, nudge : Ctrl+Z / Ctrl+C / Ctrl+V and arrow-key nudging.
• 6 languages - English, Turkish, Français, Deutsch, Español, 日本語.
• Themes - Several dark themes to match your vibe.

Who it’s for
