About Base64 Decode

What Is Base64?

Base64 is a way of representing binary data (or any text, including non-ASCII characters) as a string of printable ASCII characters. It's commonly used to embed data in places that only support text, such as email attachments, data URLs in CSS/HTML, JSON payloads, and authentication headers - it does not encrypt or compress data, it just re-encodes it.
