Base64 Encoding & Decoding Tips

How It Works

  • Base64 encoding converts text or binary data into a string of ASCII characters.
  • It's commonly used for data transfer, storage, and embedding binary data in text files.
  • Decoding reverses the process, converting Base64 back to the original text or data.

Common Use Cases

  • Encoding images or files for web and email transfer
  • Storing binary data in databases as text
  • Embedding data in HTML, CSS, or JSON
  • Debugging and testing data transmission

Best Practices

  • Always verify the decoded output for correctness
  • Be cautious with large files, as Base64 increases data size by ~33%
  • Use secure transfer methods for sensitive data
