Morse code
How to use it
- Pick a direction: Text → Morse or Morse → Text. The conversion happens as you type — no button to press.
- Type or paste your text, or Morse code. Clearing the box resets the result instantly (R6).
- Use “Sample” to fill in an example, and Copy or Download to save the result.
- Turn on “Play sound” to hear the Morse as short (dot) and long (dash) beeps — it only plays locally, in your browser.
Example
Text
Hello, world!
Morse code
.... . .-.. .-.. --- --..-- / .-- --- .-. .-.. -.. -.-.--
Letters are separated by a space and words by “ / ”. Morse has no upper/lower case, so decoded text comes back in capitals.
Rules, limits and known issues
- Strict ITU standard only: A–Z, 0–9 and a defined set of punctuation. Characters outside that set (Chinese, Arabic, emoji) are reported as errors, never silently dropped.
- Morse does not carry case, so decoded text is always upper-case.
- On decode, words may be separated by “/”, “|” or a new line — all are accepted.
- Size limit 50,000 characters. Nothing is uploaded, stored, written to the URL or shared: the share button only shares this page address.
- The “Play sound” button uses your browser’s audio and plays once; it is a demonstration, not a professional telegraph key.
