About Base64

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding data that needs to be stored or transferred over media designed to handle text.

Common uses:
  • Embedding images in HTML/CSS (data URIs)
  • Encoding authentication credentials
  • Email attachments (MIME)
  • Storing binary data in JSON or XML
  • URL-safe data encoding

Note: Base64 is an encoding scheme, not encryption. It provides no security and encoded data can be easily decoded.
