How to display Base64 images in HTML?
To display images encoded with Base64, you need to get the base64 encoded string and use the img element. This prevents the page from loading slowly and saves the web browser from additional HTTP requests.
Base64 images are embedded directly into HTML using Data URLs, which eliminate the need for separate image files. This technique is useful for small images, icons, or when you want to reduce HTTP requests.
Syntax
Following is the syntax for displaying a Base64 image in HTML
<img src="data:image/[format];base64,[base64-string]" alt="description" />
Where
-
[format]is the image format (jpeg, png, gif, webp, etc.) -
[base64-string]is the actual Base64 encoded image data
Data URL Structure
The Data URL for a Base64 image has two main parts
-
MIME type declaration
data:image/jpeg;base64,specifies the image format - Base64 encoded string The actual image data converted to Base64 format
Basic Example
Following example shows how to display a Base64 image in HTML
<!DOCTYPE html>
<html>
<head>
<title>Base64 Image Display</title>
</head>
<body style="font-family: Arial, sans-serif; padding: 20px;">
