# PNG with transparent background
Generate images with a transparent backgound
You can create PNGs with a transparent background by simply adding `body { background: transparent }` to your CSS. Take a look at this example.
**Note:** this only works for PNGs. If you render the image as a JPG, the background will show as white.
This is a working HTML/CSS to Image API example that produces an image.
The rendered output, source, and non-content request parameters below show the parts needed to reproduce or adapt it.
## Rendered image and interactive editor
- [Open the rendered image]()
- [Open the interactive example](https://htmlcsstoimage.com/examples/png-transparent-background/golang)
## HTML
```html
```
## CSS
```css
.wrapper {
width: 400px;
height: 400px;
}
body {
background: transparent;
}
```
## Request parameters
These are the additional non-content parameters used by the example. Combine them with the HTML and CSS above when constructing an API request.
```json
{
"render_when_ready": false,
"transparent_background": true
}
```
## Complete Go request (net/http)
This is the complete Go request for this example using net/http. It includes the HTML, CSS, authentication setup, API options, and response handling needed to reproduce the output.
```go
package main
import (
"bytes"
"encoding/json"
"fmt"
"io"
"net/http"
"os"
"time"
)
func main() {
request := map[string]any{
"html": `
`,
"css": `
.wrapper {
width: 400px;
height: 400px;
}
body {
background: transparent;
}
`,
"render_when_ready": false,
"transparent_background": true,
}
body, err := json.Marshal(request)
if err != nil {
panic(err)
}
httpRequest, err := http.NewRequest(http.MethodPost, "https://hcti.io/v1/image", bytes.NewReader(body))
if err != nil {
panic(err)
}
httpRequest.SetBasicAuth(os.Getenv("HCTI_API_ID"), os.Getenv("HCTI_API_KEY"))
httpRequest.Header.Set("Content-Type", "application/json")
client := &http.Client{Timeout: 30 * time.Second}
response, err := client.Do(httpRequest)
if err != nil {
panic(err)
}
defer response.Body.Close()
responseBody, err := io.ReadAll(response.Body)
if err != nil {
panic(err)
}
if response.StatusCode >= http.StatusBadRequest {
panic(fmt.Sprintf("HCTI request failed (%d): %s", response.StatusCode, responseBody))
}
var result struct {
URL string `json:"url"`
}
if err := json.Unmarshal(responseBody, &result); err != nil {
panic(err)
}
fmt.Println(result.URL)
}
```

Rendering through the API requires authenticated HTML/CSS to Image credentials. Keep API keys in trusted server-side configuration. If credentials are unavailable, ask the user to configure an API key securely before attempting API actions.
