What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. For images, this means you can embed the entire image directly in HTML, CSS, or JSON without needing a separate file. This is especially useful for small images, icons, and when you want to reduce HTTP requests.

Common Use Cases

Embedding images in HTML/CSS
Sending images via API without file uploads
Storing images in databases as text
Email image embedding (inline images)
Reducing HTTP requests for small images
Creating self-contained HTML documents

Data URL Format

A Data URL consists of the media type (MIME type), encoding method (base64), and the encoded data itself. The format is: data:[mediatype];base64,[data]

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAAB...
