Base64 Encoding is a method used to convert binary data into a text format. This is done by encoding the data into a set of 64 different characters, which include letters, numbers, and symbols. This makes it easier to transmit data over media that are designed to handle text, such as email or web pages. The main advantage of Base64 Encoding is that it ensures data remains intact without modification during transport. It is commonly used in various applications, including embedding images in HTML or sending files in JSON format, where binary data needs to be represented as text.
