What Is Base64 Encoding?
Base64 is a way of converting data into a text-safe format using a limited set of ASCII characters. It is commonly used
when data needs to be transferred through systems that are designed to handle text only.
In web development, Base64 is often used for API data, tokens, email attachments, and embedded resources such as images or files.
It does not encrypt data, but it helps represent data in a format that is easier to transmit and store in text-based environments.
Common Uses of Base64
Encoding text for APIs and web requests
Embedding small images in HTML or CSS
Email attachment handling
Representing binary data in text format
Testing encoded input and output during development
