Capsule Generator
Create professional Steam capsule art with text-to-image generation. Design eye-catching game headers that stand out in the Steam store.
What is the Capsule Generator?
The Capsule Generator is a powerful tool designed specifically for indie game developers who need professional-quality capsule art without the budget for a dedicated artist. Steam capsule images are the first thing potential players see when browsing the store, making them crucial for your game's success.
This tool uses advanced image generation technology to create unique background images and game title graphics based on your text descriptions. You can then customize these elements with built-in editing tools to create the perfect capsule for your game.
How It Works
Using the Capsule Generator is straightforward, even if you've never designed graphics before:
1. Generate Background Image
Enter a detailed description of the visual you want for your capsule background. The more specific you are, the better the results.
Click "Generate Background" to create your image. This costs 10 credits per generation.
- •Be specific about the art style (e.g., "pixel art", "realistic 3D render", "hand-drawn illustration")
- •Include mood and atmosphere (e.g., "dark and mysterious", "bright and cheerful", "epic and dramatic")
- •Mention key elements you want to see (e.g., "a medieval castle at sunset", "futuristic city with neon lights")
- •Reference your game genre to set the right tone (e.g., "horror survival game atmosphere", "cozy farming game vibes")
2. Generate Game Title
Enter your game's title and describe the style you want for the text.
Click "Generate Title" to create title graphics with transparent backgrounds. This costs 5 credits per generation.
The generated title will automatically have its background removed, making it easy to place over your capsule background.
- •Specify the font style you want (e.g., "bold futuristic font", "handwritten medieval text", "pixelated retro font")
- •Describe any effects (e.g., "glowing text", "metallic finish", "dripping blood effect")
- •Keep titles short and readable - long titles may not fit well on capsules
- •Consider how the title color will contrast with your background
3. Edit and Customize
Once you have your background and title, you can use the canvas editor to perfect your capsule:
Click on the title text to select it - handles will appear around it for editing. Click on empty space to deselect and edit the background instead.
When the title is selected, you can drag it to reposition, use corner handles to resize, and rotate it as needed.
Apply filters to enhance your images using the filter panel on the right.
4. Available Filters
Both the background and title can be enhanced with various filters:
- •Blur: Soften the image or create depth of field effects
- •Brightness: Lighten or darken your image
- •Contrast: Make colors pop or create a flatter look
- •Enhance: Sharpen details and improve clarity
- •Grayscale: Convert to black and white
- •Hue: Shift the color palette
- •Saturation: Make colors more vivid or muted
- •Luminance: Adjust overall lightness
- •Pixelate: Create retro pixel art effects
5. Download Your Capsule
Once you're happy with your design, click "Download as ZIP" to get all the Steam capsule formats you need:
The download includes properly sized images for all Steam capsule types, ready to upload to your store page.
Best Practices for Different Game Genres
The style of your capsule should match your game's genre and target audience. Here are some guidelines for common genres:
Horror Games
Use dark, atmospheric backgrounds with limited color palettes
Consider desaturated colors or high contrast black and white
Unsettling imagery works better than explicit gore
Font choices: distressed, handwritten, or angular fonts work well
Puzzle Games
Clean, bright backgrounds that aren't too busy
Show the core puzzle mechanic if possible
Use pleasant, inviting colors
Font choices: clean, modern, easily readable fonts
Action/Adventure Games
Dynamic, energetic compositions
Show the protagonist or key action moment
Bold, saturated colors
Font choices: strong, bold fonts that convey excitement
Cozy/Casual Games
Warm, inviting color palettes
Friendly, approachable imagery
Soft lighting and gentle compositions
Font choices: rounded, friendly fonts
Strategy/Simulation Games
Clear, organized compositions
Show scope and scale of the game world
Professional, polished appearance
Font choices: clean, authoritative fonts
Common Mistakes to Avoid
Creating effective capsule art takes practice. Here are common pitfalls to avoid:
- •Too much text: Keep your title short and impactful. Players browse quickly and won't read paragraphs
- •Unclear focal point: Your capsule should have one clear subject or message
- •Poor contrast: Make sure your title is readable against the background
- •Generic imagery: Your capsule should be distinctive and memorable, not generic stock imagery
- •Inconsistent style: The background and title should feel like they belong together
- •Ignoring the thumbnail: Your capsule needs to look good at small sizes too
Tips for Better Prompts
The quality of your generated images depends heavily on your prompt. Here's how to write effective prompts:
- •Start with the main subject, then add details
- •Include specific art styles or artist references if you have them in mind
- •Describe lighting and atmosphere (e.g., "dramatic side lighting", "soft morning light")
- •Mention perspective and composition (e.g., "top-down view", "close-up portrait")
- •Use descriptive adjectives (e.g., "ancient", "gleaming", "overgrown", "ethereal")
- •If the first result isn't perfect, try rewording your prompt with more specific details
- •Experiment with different phrasings - sometimes small changes make big differences
Understanding the Editor Controls
The canvas editor gives you precise control over your capsule design:
Selecting Elements
Click on the title text to select it - you'll see transformation handles appear around it
Click on empty space or the background to deselect the title and edit the background instead
The filter panel on the right shows which element is currently selected
Transforming the Title
Drag the title to move it anywhere on the canvas
Drag the corner handles to resize while maintaining proportions
Use the rotation handle to angle your title
Position your title where it doesn't cover important background details
Applying Filters
Use the filter sliders to adjust the selected element in real-time
Filters can be combined - try multiple filters together for unique effects
If you go too far, you can always adjust the sliders back
Remember: subtle adjustments often look more professional than extreme effects
Credit Costs
The Capsule Generator uses a credit-based system to keep costs predictable:

- •Title generation: 5 credits per title (includes automatic background removal)
