## Four ways to generate images

### [From HTML/CSS →](/getting-started/using-the-api/)

Send HTML and CSS to render an image or PDF. Use your own layouts, fonts, and JavaScript.

```http
POST https://hcti.io/v1/image


{
  "html": "<h1>Hello world</h1>",
  "css": "h1 { color: #00b980; }"
}
```

### [From a URL →](/getting-started/url-to-image/)

Screenshot a public webpage, capture the full page, or crop to a specific element.

```http
POST https://hcti.io/v1/image


{
  "url": "https://example.com",
  "full_screen": true
}
```

### [From a template →](/getting-started/templates/)

Design a template in the visual editor or with HTML/CSS, then generate images with different text, images, and data.

```http
POST https://hcti.io/v1/image/TEMPLATE_ID


{
  "template_values": {
    "title": "Hello world"
  }
}
```

### [Automatic Open Graph images →](/getting-started/og-images/)

Connect your website or CMS and generate a social card for each page from its screenshot or metadata.

```html
<head>
  <meta
    property="og:image"
    content="https://hcti.io/v1/og/DOMAIN_ID/"
  >
</head>
```
