What Is Base64 Image Encoding?
Base64 is a way to encode binary data (like image files) as plain ASCII text. It's commonly used in CSS background-image: url(data:image/png;base64,...), HTML <img src="data:..."> attributes, JSON APIs, email attachments (MIME), and SVG files.
This decoder accepts both raw Base64 strings and full data: URIs. It also handles JPEG, WebP, and GIF Base64 strings - they're all decoded and saved as PNG for maximum compatibility.
