Why is r64 conversion usefull for an email application?

R64 conversion, commonly referred to as Base64 encoding, is useful for email applications because it allows binary data, such as images or files, to be transmitted over protocols that only support text. This ensures that the data remains intact and is not altered during transmission, as email systems may not handle raw binary data properly. Additionally, Base64 encoding increases the compatibility of attachments across different email clients and platforms, making it easier for users to send and receive multimedia content seamlessly.
