Base64 Encoding Explained: How It Works and Why It Matters

Base64 encoding converts binary data into 64 printable characters, using A-Z, a-z, 0-9, +, and / to represent 6 binary bits each. It ensures error-free content transmission between gateways and increases data volume by about one-third. Common applications include small image optimization in front-end development, file reading, and Canvas image generation. While useful for reducing HTTP requests, Base64 is not suitable for large files due to increased data size.
