How to use the text to binary converter

  1. Type text and click Text → Code.
  2. Choose binary, hex, decimal or octal output.
  3. Paste codes and click Code → Text to decode them.

Text is encoded as UTF-8, so every language and emoji works: Latin letters take one byte, Cyrillic two and emoji four. Binary output uses 8-bit groups. Useful for computer-science homework, puzzles and debugging encodings.
