Base64 Encoding Explained: How Binary Data Becomes Text

Base64 Encoding Explained

Base64 is a binary-to-text encoding scheme that represents binary data in 64 ASCII characters (A-Z, a-z, 0-9, +, /).

Why Use Base64? HTTP headers, email systems, and URLs were originally designed for text. Base64 ensures binary files (like image icons or secret keys) can pass through text-only transmission channels without corruption.
