What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in a readable ASCII string format. It's commonly used to transmit data that needs to remain intact without modification during transport, such as embedding image data directly in an HTML or CSS file, or sending binary attachments in emails.
