# Adding a watermark

Aan image can be inserted to a custom stylesheet as a watermark with the following CSS code:

```css
@page {
  background-image: url("https://www.meta-inf.hu/download/attachments/36405251/header_background_main.jpg");
  background-position: center center;
  background-repeat: no-repeat;
  margin-top: 4cm;
}
body{
  background-color: transparent;
}
```

{% hint style="warning" %}
**Important:**

* We do not download the images in CSS for processing, so you have to use absolute URL to be reachable during conversion.
* The converter has no authorization information, so the resource must be accessible anonymously.
* The body has a white background, so it must be removed.
  {% endhint %}
