# Add image generation without managing Chromium

Use HTML, CSS, JavaScript, and web fonts you already know. The API runs the browser and returns a hosted image URL your application can use immediately.

## Key capabilities

- Chromium rendering
- Viewport and format controls
- Image ID and hosted URL

## Generate an image from HTML and CSS

Send the HTML and CSS that define the image to `POST https://hcti.io/v1/image`. HTML/CSS to Image (HCTI) renders the content in headless Chromium and returns an image ID with a hosted URL.

```json
{
  "html": "<main class=\"card\"><h1>Weekly report</h1></main>",
  "css": ".card { padding: 48px; background: white; }"
}
```

Use browser-supported layout tools, web fonts, SVG, and JavaScript without maintaining your own screenshot browser. Set dimensions, device scale, output format, transparency, and other image options in the same request.

## MCP Integration

Connect an MCP-compatible client to `https://mcp.hcti.io` with OAuth. The tools use the connected organization's HTML/CSS to Image account, permissions, and plan limits.

- The `create_image` tool renders HTML and CSS as an image and returns the hosted image URL. Use it to create visual summaries, social cards, reports, and other application-generated graphics.

### Existing frontend components

Reuse browser-supported layout techniques, web fonts, SVGs, and JavaScript-rendered content.

## Get started

REST API requests require an HTML/CSS to Image account and should be authenticated from trusted application code. Check the API docs and pricing for current setup instructions, limits, and feature availability.
