What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. It is designed to carry data stored in binary formats across channels that only reliably support text content.

Common Use Cases

  • Data URIs: Embedding small images or fonts directly into CSS or HTML files (e.g., data:image/png;base64,...).
  • Email Attachments: Sending binary files via SMTP.
  • Basic Auth: Encoding username:password credentials in HTTP headers.
