About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data as ASCII strings. It's commonly used for encoding data in email, URLs, and storing complex data in text format.

Use cases: Email attachments, data URLs, JSON Web Tokens (JWT), API authentication, and storing binary data in databases.

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It uses 64 characters (A-Z, a-z, 0-9, +, /) to encode data, making it safe for transmission over text-based protocols like HTTP and email.

Common Use Cases for Base64

Email attachments (MIME encoding)
Data URLs for embedding images in CSS/HTML
JSON Web Tokens (JWT) encoding
API authentication and authorization
Storing binary data in databases
Web development and data transmission

Base64 vs Other Encodings

Unlike hexadecimal encoding which uses 16 characters, Base64 uses 64 characters making it more efficient for representing binary data. It is also more readable than raw binary data and is widely supported across different systems and programming languages.
