What is Base64 Image Encoding?

Base64 encoding converts binary image data into ASCII text characters. This allows images to be embedded directly in HTML, CSS, or JSON without requiring separate file requests. The encoded string is approximately 33% larger than the original binary data but enables inline image embedding.

Common Use Cases

Embedding images directly in HTML or CSS (Data URIs)
Storing images in databases as text
Sending images via APIs or JSON payloads
Including images in email templates
Reducing HTTP requests for small icons and graphics
Storing images in localStorage or sessionStorage

Data URL Format

A Data URL consists of four parts: the scheme (data:), the MIME type (image/png), the encoding type (;base64,), and the encoded data. For example:

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

Privacy & Security

All image processing happens entirely in your browser using the FileReader API. No data is uploaded to any server, ensuring your images remain private and secure.
