What is Base64 and URL encoding?
Base64 converts arbitrary text or binary data into a string of printable ASCII characters. It's commonly used to embed data (like images or tokens) inside JSON, HTML, or email, where raw binary or special characters wouldn't survive transport unchanged.
URL encoding (percent-encoding) replaces characters that aren't safe in a URL - such as spaces, `&`, or `?` - with a `%XX` escape sequence, so the string can be safely used as a query parameter or part of a URL path.
