For save to file

$imgBase64 = str_replace('data:image/jpeg;base64,', '', $image);
$imgBase64 = str_replace(' ', '+', $imgBase64);
file_put_contents('file.jpg', base64_decode($imgBase64));

Hi, thanks for sharing the code. is it possible to increase the screen shot size so text inside the image is readable and clear?

A version that provides more dynamic attributes injection flexibility.
https://gist.github.com/yookoala/6ccba4adfd0b3ba59fb2a1d9e4393099

Example usage:

// change width height
// Output: <img src="..." class="thumbnail" style="width: 100px; height: 100px" />
echo getGooglePageSpeedScreenshot($_GET['url'], ['class' => 'thumbnail', 'style' => ['width: 100px;', 'height: 100px;']]);

// entirely depend on CSS class
// Output: <img src="..." class="thumbnail custom-size" />
echo getGooglePageSpeedScreenshot($_GET['url'], ['class' => ['thumbnail', 'custom-size']]);
