What is Image to Base64 Conversion?
Image to Base64 conversion is the process of transforming binary image data into a text-based Base64 string. This encoded string can then be embedded directly inside HTML, CSS, JSON responses, or API requests.
Instead of referencing an external image file, developers sometimes embed the Base64 string directly in the webpage. This is known as a Data URL.
Example of Base64 Image
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..." />
In this example, the browser reads the Base64 encoded string and renders the image without needing to download a separate image file.
