What Is Base64?
Base64 is an encoding scheme that represents binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). It is widely used to safely embed data in text-based formats such as JSON, URLs, email (MIME), and HTML data: URIs, where raw binary bytes would otherwise cause corruption or parsing errors.
Common Uses
- Embedding small images directly in CSS or HTML.
- Encoding API keys or tokens for transport in headers.
- Decoding JWT payloads or email attachments for inspection.
