how to convert html to image

I am making an API in laravel lumen. I want to convert blade file into image in laravel. First I am converting blade file into html and then html to image. blade to html is converting, but how to convert html to image?

I have to return path of converted image in response.

my controller is:

public function savecard()
{
$result = json_decode(json_encode($result), true);
        $destinationPath = storage_path('uploads/card_html/');
        $new_path = str_replace('\', '/', $destinationPath);

        $html = view($selected_template,compact('result'));
        $html = $html->render();
        File::put($new_path.$html_save, view($selected_template,compact('result'))
                ->with(['CardSave' => $html, 'message' => 'Success'])
                ->render()
                );
}

in above code $result is coming from query and it will show on blade file. But after that, how to convert html to image.
