Fun Fact
Base64 encoding increases file size by approximately 33% compared to the original binary file. While it adds overhead, it enables binary data like GIF images to be safely transmitted over text-only systems such as email protocols and JSON APIs.
Historical Context
The GIF format was introduced in 1987 and became widely popular for lightweight web animations. Base64 encoding emerged as part of MIME standards to allow binary attachments within text-based internet protocols. Together, they enabled early web developers to embed animated content directly into markup long before modern asset pipelines existed.
