A short scientific explanation of what the tool does, when to use it, and what kind of output to expect.

Base64 converts text or binary-safe content into an ASCII representation that is easier to move through APIs, configuration files, URLs, and transport layers. Decoding restores the original text when the input is valid Base64.
