About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents 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.

  • Ensures that data remains intact without modification during transport
  • Widely used for encoding email attachments, form data in web applications, and more
  • Makes it possible to embed binary data in text files like JSON or XML

This tool uses standard JavaScript functions for Base64 encoding and decoding, ensuring compatibility with all modern web applications.
