What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses 64 printable characters (A-Z, a-z, 0-9, +, /) to encode data, making it safe for transmission over text-based protocols like email or HTTP.
Common Uses of Base64
- Embedding images in HTML/CSS (data URIs)
- Encoding email attachments (MIME)
- Storing complex data in JSON or XML
- Basic HTTP authentication headers
- Encoding binary data for API transmission
