How Base64 Decoding Works

Base64 decoding reverses the encoding process. It takes the Base64 string (which uses 64 characters: A-Z, a-z, 0-9, +, /) and converts it back into the original binary data or text.

Common Uses

  • Debugging: Inspecting encoded data in logs or APIs.
  • Data Recovery: Extracting information from data URIs.
  • Security Analysis: Decoding obfuscated strings in malware or scripts.

Example

Base64: SGVsbG8gV29ybGQ=

Text: "Hello World"
