# Add webpage-to-PDF conversion without managing Chromium

Send a public URL with browser and PDF settings. The API handles Chromium, capture timing, rendering, file storage, and delivery.

## Key capabilities

- One URL to PDF request
- Browser and timing controls
- Hosted Chromium rendering

## How the URL to PDF API works

Send a public webpage URL to `POST https://hcti.io/v1/image` with `pdf_options`. HTML/CSS to Image (HCTI) loads it in Chromium before generating the PDF. Browser controls cover JavaScript-rendered content, capture timing, color scheme, timezone, and print media. The response includes the generated PDF URL.

The page must be reachable by HCTI. Pages that require a specific source network can use a saved proxy, but a site may still return a login, rate-limit, or browser-challenge page instead of its normal content.

If the content is not available as a public webpage, use the HTML-to-PDF API and send its HTML and CSS instead.

## Control the PDF layout

Set the PDF page width, height, scale, print backgrounds, and each margin in the same API request.

```json
{
  "pdf_options": {
    "page_width": "8.5in",
    "page_height": "11in",
    "margins": ["0.4in", "0.4in", "0.4in", "0.4in"],
    "print_background": true
  }
}
```

PDF output is available on supported plans. Check [pricing](https://htmlcsstoimage.com/pricing.md) for current availability.

## 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_url_image` tool accepts a webpage URL with `pdf_options` and returns the generated PDF URL. Include browser timing and print controls for JavaScript-rendered pages.
