What is Base64 Image?

Where can be used Base64 encoded image?

It can be used in Data URI scheme.
With this technique you can prevent multiple HTTP requests, reducing the loading time of a web page.
By using Data URI scheme you can force the e-mail client to display your images sent via e-mail. This is very helpful in newsletters.

Examples for usage of Base64 encoded image with Data Uri

Html example - Image tag

   
 <html><body>
    <img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABA......" />
</body></html>
                

CSS example - Background image

   
 <style type="text/css" > 
 div.my-image { width:150px;
                height:150px; 	
                background-image: url("data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABA......");
              }
 </style>
                

PHP example - convert image to Base64 string

  
function image_to_base64($path_to_image)
{ 
    $type = pathinfo($path_to_image, PATHINFO_EXTENSION);
    $image = file_get_contents($path_to_image);
    $base64 = 'data:image/' . $type . ';base64,' . base64_encode($image);
}
                

C# example - method for convert image to Base64 string
