Base64 Encoder/Decoder

Encode text to Base64 or convert images to data URIs.

About Base64

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for embedding data in HTML, CSS, and emails.

Use Cases

  • Embedding images in HTML/CSS
  • Sending binary data via text protocols
  • Storing complex data in URLs
  • Email attachments (MIME)

Note

Base64 encoding increases data size by approximately 33%. Use it for small images or when embedding is necessary.
