📖 What is Base64?

Base64 encodes binary data as ASCII text, using 64 characters (A-Z, a-z, 0-9, +, /).

Commonly used for embedding images, sending binary in JSON, and email attachments.

🔧 Common Uses

• Data URIs for images
• Basic HTTP authentication
• Encoding binary in APIs
• Email attachments (MIME)

💡 Tips

→ Base64 increases size by ~33%
→ Not encryption, just encoding
→ URL-safe variant uses -_ instead of +/
