About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters. It's widely used in web development, APIs, email attachments, and data storage.

Common Uses of Base64

Embedding images in HTML/CSS as data URIs
Encoding binary data in JSON APIs
Basic authentication headers (username:password)
Email attachments (MIME encoding)
JWT (JSON Web Token) payload encoding

Base64 vs Encryption

Base64 is NOT encryption — it's just encoding. Anyone can decode a Base64 string. For secure data, always use proper encryption like AES.
