Base64 transforms binary data into ASCII text. Essential for data URIs, APIs, and authentication.

How It Works

Groups 3 bytes into 4 Base64 characters. Ideal for transmitting binary in text formats.

Common Use Cases

• Data URIs - Inline images in CSS/HTML
• API Keys - Basic authentication
• Tokens - JWT payload encoding

Important Notes

• Increases size by ~33%
• Not encryption - just encoding
• Safe for transport, not security

Conclusion
