How to Embed PNG Images Directly into HTML Without External Files?

Embedding PNG Images into HTML Pages

The task of embedding a PNG image into an HTML page without linking to the image file raises the question: how to incorporate the image data directly into the HTML?

Embedding with Base64 Encoding

Base64 encoding provides a solution to embedding images into HTML. There are various online Base64 encoders available, but it's recommended to use a robust one like the one found at http://www.greywyvern.com/code/php/binary2base64.

This tool presents two primary embedding options: using CSS or the tag.

CSS Embedding

In CSS, embedding can be achieved as follows:

<code class="css">div.image {
  width:100px;
  height:100px;
  background-image:url(data:image/png;base64,iVBORwA<MoreBase64StringHere>);
}</code>

Tag Embedding

Alternatively, the tag can be used:

<code class="html"><img alt="My Image" src="data:image/png;base64,iVBORwA<MoreBase64StringHere>" /></code>

By utilizing Base64 encoding, you can embed PNG images directly into HTML pages, enabling the display of images without the need for external image files.
