What Is Base64 Encoding?

Base64 is a method of converting binary or text data into an ASCII string format. It allows data to be transmitted safely through systems that handle text-based content, such as HTML, JSON, or email protocols.

Developers often use Base64 when embedding images in CSS or HTML, transmitting API payloads, or protecting raw binary data during transfer.

Why Use a Base64 Encoder or Decoder?
