Fun Fact
Base64 encoding increases the size of an image by roughly 33%, yet it remains extremely popular because it allows binary data to live safely inside plain text formats that would otherwise reject raw image bytes.
Historical Context
The BMP format is one of the oldest image formats in computing, originating with early versions of Microsoft Windows. Base64, on the other hand, emerged from email systems that needed a way to transmit binary attachments over text-only protocols. Combining these two technologies enables classic image files to be used seamlessly in modern web and software environments.
