How to use

Choose Encode or Decode, paste text into the input area, and run the conversion. Copy the output, swap it into the input, or clear the tool.

Converts Unicode text to Base64 and decodes Base64 back to Unicode locally. It supports more than ASCII by encoding text as UTF-8 bytes first.

Invalid Base64 input is rejected with a clear error.
