A tiny icon embedded directly into a CSS file as Base64 text skips an entire separate HTTP request a browser would otherwise have to make just to fetch a small image file, and an email's HTML body that can't reliably load external images at all needs that same image data embedded directly inline instead. This tool converts an image into a Base64 data URL or decodes one back into an actual image file, moving in either direction between the two.
