What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored and transferred over media designed to deal with text.

Common Use Cases:

How It Works:

Base64 encoding converts every 3 bytes of binary data into 4 ASCII characters. The character set used consists of A-Z, a-z, 0-9, +, and /, with = used as a padding character. This encoding increases data size by approximately 33%.

Example:

Original Text: "Hello, World!"

Base64 Encoded: "SGVsbG8sIFdvcmxkIQ=="
