What Is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed images in HTML/CSS, transmit binary data over text-based protocols like email (MIME), and encode data in URLs and APIs.

This free Base64 encoder/decoder tool converts text and files to Base64 and back in real time. It properly handles UTF-8 characters, supports drag-and-drop file encoding, and can generate Data URI strings for embedding images directly in your code.

Common Use Cases

  • Embedding images in HTML/CSS as Data URIs
  • Encoding binary attachments for email (MIME)
  • Transmitting data in JSON APIs and webhooks
  • Storing binary data in text-based databases or config files
  • Encoding authentication credentials (HTTP Basic Auth)
