Base64 Encoder & Decoder

Encode text to Base64 and decode Base64.

How it works

  • Text is first encoded as UTF-8 bytes, then those bytes are converted to Base64.
  • Base64 decoding reconstructs bytes and then decodes them as strict UTF-8 text.

Example

  • “UnicodeWorks” becomes a Base64 string that can be decoded back to the original UTF-8 text.

Assumptions and limitations

  • Base64 is an encoding, not encryption; anyone can decode it.
  • Arbitrary binary files are outside this text-focused tool.

FAQ

Does Base64 hide or secure text?

No. Base64 is reversible representation for bytes, not encryption and not a security control.
