About This Tool
A free, browser-based Morse code translator with audio playback.
What It Does
morsecodetranslatortool.com is a free online Morse code translator. It converts English text into Morse code and decodes Morse code back into English. All translation happens entirely in your browser — no text is sent to a server, no account is required, and the tool works offline once the page has loaded.
Features
- Bidirectional translation — text to Morse or Morse to text, swap with one click.
- Audio playback with adjustable speed from 5 to 40 words per minute (WPM), using the standard PARIS timing definition.
- Farnsworth timing — an evidence-based learning method that keeps individual character speed high while widening inter-character spacing, enabling fluent pattern recognition from the start.
- Adjustable sidetone pitch from 400 to 1000 Hz, matching the range used by modern CW receivers.
- International Morse (ITU-R M.1677-1) and American (Railroad) Morse as used by 19th-century U.S. telegraph companies.
- Screen flash output for visual Morse practice.
- Copy-to-clipboard for outputs.
- Mobile-friendly, responsive layout that works on phones, tablets, and desktops.
Standards Implemented
International Morse code follows the official ITU-R M.1677-1 recommendation, including letters A–Z, digits 0–9, and the standard punctuation set. American (Railroad) Morse follows the conventions documented in 19th-century telegraph training manuals, with spaced characters and the distinct C, J, L, O, Q, R, X, Y, Z codings that differ from international Morse.
Why This Tool Exists
Most online Morse code translators do one thing: convert a string of text into dots and dashes. That's useful for a school assignment but falls short for anyone actually learning Morse — for which you need correct audio timing, adjustable speeds, Farnsworth pacing, and a rendering of the prosigns and punctuation used on the air by amateur radio operators. This tool aims to fill that gap: a single-purpose Morse translator that's accurate enough for learners, respectful of the existing ham radio conventions, and free of account walls or paid tiers.
Accuracy and Corrections
Every entry in the translation tables has been cross-checked against published references. If you spot an error — especially in American Morse, where online sources often diverge — please send a correction with a citation to contact@morsecodetranslatortool.com.

Not for Emergency Use
While the tool accurately renders the SOS distress signal and related emergency conventions, it is an educational resource. In a real emergency, contact local emergency services by direct means.
