A Base64-encoded image can be embedded directly inside HTML or CSS code, eliminating the need for a separate image file or HTTP request.<\/p>\n<h2>When Should You Use a Base64 Image?<\/h2>\n<p>Base64 images are useful in a few specific situations: embedding small icons or logos directly in HTML emails (avoiding blocked image requests), including images in JSON API responses, inlining images in CSS for single-file components, and embedding images in environments that don&#8217;t support external file links.<\/p>\n<h2>How Do I Use a Base64 String in HTML?<\/h2>\n<p>Use it as the value of an <code>src<\/code> attribute with the data URI prefix:<\/p>\n<pre><code>&lt;img src=\"data:image\/png;base64,YOUR_BASE64_STRING_HERE\" alt=\"My image\" \/&gt;<\/code><\/pre>\n<h2>How Do I Use a Base64 String in CSS?<\/h2>\n<p>Use it as a background image URL:<\/p>\n<pre><code>background-image: url(\"data:image\/png;base64,YOUR_BASE64_STRING_HERE\");<\/code><\/pre>\n<h2>Does Base64 Make the File Size Larger?<\/h2>\n<p>Yes \u2014 Base64 encoding increases file size by approximately 33% compared to the original binary file. This is a trade-off worth making for small images and icons, but for large photos it&#8217;s better to host the file separately.<\/p>\n<h2>What Image Formats Are Supported?<\/h2>\n<p>JPG, PNG, WebP, SVG, and GIF.
