Lumena makes creating Steam store art simple. All 9 required capsule sizes in one project, each with its own layer stack. Design once, export everything correctly sized.

Layers
Image, text, particle, light, and gradient layers. Group them into folders. 6 blend modes, opacity control, flip, resize, and multi-select operations.

30+ Real-Time Effects
Blur, sharpen, vignette, chromatic aberration, drop shadow, outer glow, inner shadow, stroke, halftone, oil paint, motion blur, posterize, color grading, and more. All stackable per layer.

Text Engine
Font selection, sizing, color, bold, italic, outline, letter spacing, line height, alignment, and text transform.

AI Tools (Local)
Background removal, 2x image upscaling (Real-ESRGAN), and depth estimation for depth-of-field effects. All running locally on your machine. Optional Gemini Flash image generation with your own API key.

Global Post-Processing
Vignette, bloom, film grain, color temperature, sharpen, and chromatic aberration applied across your composition.
