You can download wkhtmltoimage from this link. There is a version for all operating systems so that shouldn't be a problem. Then you can use it like so:

$path="wkhtmltoimg/wkhtmltoimage.exe"; //path to your executable
$url="http://google.com";
$output_path="test.png";
shell_exec("$path $url $output_path");

One thing you want to note is that if PHP is in safe mode, shell_exec will not work and you won't be able to do your conversion.

You can use PHP PhantomJS to save a screen capture of a HTML page to the local disk:

<?php

use JonnyW\PhantomJs\Client;

$client = Client::getInstance();

$width  = 800;
$height = 600;
$top    = 0;
$left   = 0;

$request = $client->getMessageFactory()->createCaptureRequest('http://example.com', 'GET');
$request->setOutputFile('/path/to/save/capture/file.jpg');
$request->setViewportSize($width, $height);
$request->setCaptureDimensions($width, $height, $top, $left);

$response = $client->getMessageFactory()->createResponse();

// Send the request
$client->send($request, $response);
