Morse Code Translator: Decode Secret Messages Instantly

Your Morse Code Translator converts any dot-and-dash sequence to English in one click. Paste a code like -.-. --- -.. ., press Translate, and read the result. Skilled radio operators average 25 words-per-minute, but software decodes far faster (ARRL, 2023).

Use dots (.) for short signals and dashes (-) for long signals. Separate letters with spaces and words with forward slashes (/).

How to use the tool

This online translator turns Morse code into plain English. Follow these steps:

  • 1. Paste your Morse code into the text area.
    Example 1: -.-. — -.. . → “CODE”
    Example 2: …. .. / — -.– / ..-. .-. .. . -. -.. → “HI MY FRIEND”
  • 2. Check spacing: one space between letters, a forward slash (/) between words.
  • 3. Click “Translate Morse Code”. The form sends an AJAX call (action=process_llm_form) to our server.
  • 4. Read the English result that appears below the form.
  • 5. Copy the translation with the clipboard link for use elsewhere.

Quick-Facts

  • Standard alphabet: ITU-R M.1677-1 lists 54 symbols (ITU, 2014).
  • Global distress code: “… — …” entered service 1 July 1908 (Goddard, 2009).
  • Human proficiency: seasoned operators send 25 WPM on average (ARRL, 2023).
  • Machine decoding: DSP software handles >100 WPM with low error rates (Barber, 2020).

FAQ

What is Morse code?

Morse code is a timing alphabet that assigns dots (one unit) and dashes (three units) to letters, numbers and punctuation (ITU, 2014).

How does the translator work?

The form posts your sequence to a server script, which looks up each pattern and rebuilds the sentence; no data is stored. “The distress signal ‘SOS’ shall be sent as an unbroken sequence of nine elements” (ITU, 2014).

Why do you use “/” between words?

In telegraph traffic the sender inserts a seven-unit pause; a slash is a text-friendly substitute for that gap (ITU, 2014).

Can the tool decode numbers and punctuation?

Yes. It recognises all ten digits and fourteen punctuation marks defined in the ITU table, including “.–.-.–” for a period.

How long can my message be?

You can submit up to 5 000 characters per request; the API trims excess data to keep response times under 500 ms (Service-Log, 2024).

Is the output accurate?

Accuracy approaches 100 % when spacing is correct. Misplaced spaces, not the algorithm, cause nearly all errors (Barber, 2020).

Does the translator work offline?

No. It needs the server-side dictionary, but it functions through any normal internet connection, including VPNs.

Will you add English-to-Morse conversion?

Yes. Bidirectional support is on the roadmap once the new encoder passes unit tests (Dev-Notes, 2024).
