What Is Base64 Used For?

Base64 turns arbitrary text or binary data into a safe set of letters, numbers, and symbols that can travel through systems that only handle plain text — email attachments, embedding images in CSS or HTML, API tokens, and config files all use it. It is not encryption: anyone can decode Base64 back to the original text instantly, so it should never be used to hide sensitive information.
