About Base64 Encoding
What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text.

Common uses for Base64:
  • Encoding binary data in email messages
  • Storing complex data in XML or JSON
  • Embedding image data directly in CSS or HTML
  • Transferring data in HTTP requests where binary might cause issues
  • Basic obfuscation (not for security purposes)
Note: Base64 encoding increases the data size by approximately 33%, as 3 bytes of data are encoded into 4 characters.
