What is Base64?

The Basics

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses 64 different characters (hence the name) to encode any binary data into a text format that's safe for transmission over text-based protocols.

Base64 Character Set:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=

How It Works

Base64 encoding takes 3 bytes (24 bits) of binary data and converts them into 4 characters (6 bits each). This ensures the encoded data can be safely transmitted through systems that only support text.

Input: 3 bytes
Output: 4 characters
Overhead: ~33%
