What is Base64 Encoding and Decoding
Base64 is a common method for converting binary data into plain text using a limited set of characters. It’s widely used to safely transmit data in places where raw bytes may break formatting—like JSON payloads, URLs, HTML, or email systems. Encoding converts readable text (or bytes) into Base64 text; decoding reverses it.
