🔤 Base64 Encoder/Decoder

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent data.

Common Use Cases

• Email Attachments — MIME encoding for binary files
• Data URLs — Embedding images in HTML/CSS
• API Authentication — Basic Auth headers
• JWT Tokens — Payload encoding

Note: Base64 is NOT encryption. It is encoding for transport, not security.
