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:

div.image {
  width:100px;
  height:100px;
  background-image:url(data:image/png;base64,iVBORwA);
}

Tag Embedding

Alternatively, the tag can be used:

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.
