What is a Base64 Image Data URI?

A Base64 Data URI embeds binary image data directly inside HTML tags, CSS background-image rules, or JSON APIs as a base64 encoded string, eliminating extra HTTP requests.

Is my image stored on a remote server when converting?

No! All image encoding and decoding are processed 100% locally in your browser memory using HTML5 FileReader API. Your images never leave your device.
