What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for embedding binary data in text-based formats like JSON, XML, or HTML.

Common Uses

• Data URLs for embedding images in HTML/CSS
• Email attachments (MIME encoding)
• JWT tokens and API authentication
• Storing binary data in JSON/XML

Security Note

Base64 is NOT encryption. It's an encoding scheme that can be easily decoded. Never use Base64 to "hide" sensitive data.
