Free online Morse code translator. Type English text and get International Morse code (ITU-R M.1677-1) instantly — letters, digits, and common punctuation, dot/dash with `/` between words. Paste raw `.-` `-...` and decode back to text. Built-in audio playback uses the Web Audio API to generate authentic dit/dah tones at adjustable WPM (5–30, default 20). Copy the output, replay the tone sequence, or print the cheat sheet for practice. 100% client-side: nothing leaves your browser, works on iPhone Safari and Android Chrome with no install.

Real-world use cases
Run a Scout troop signaling badge night with real dit-dah audio
A scoutmaster preps 12 kids for the signaling merit badge. Type each kid's name, drop WPM to 5, and hit Play so they hear the gaps between letters instead of guessing from a printed chart. Print the cheat sheet, then quiz them by ear. At 5 WPM "SOS" is `... --- ...` with long silences, which is exactly what a beginner needs to lock the rhythm before speeding up.
Decode a `.- -...` string a friend texted you
Someone messages you `.... . .-.. .-.. ---` with no spaces you trust. Paste it into the decode box. The tool treats single spaces as letter gaps and `/` or 3+ spaces as word gaps, so it resolves to HELLO in one step. No need to count dots by hand against a 26-row table at 1am.
Embed a hidden Morse Easter egg in an escape-room puzzle
A game designer hides a 4-letter door code in a flickering LED prop. Encode the code to Morse, then use Play at 8 WPM to record the exact dit-dah timing as the blink pattern. Players who know `-.-.` is C crack it; everyone else hears noise. The audio export keeps the LED and the sound file perfectly in sync.
Practice for a HAM CW exam segment on your phone during a commute
A radio license candidate has 20 minutes on the train. Type a random callsign like W1AW, set WPM to 18 (near the on-air range), and copy by ear with eyes closed. Because it is 100% client-side it works in a tunnel with no signal, and the silent-mode tip in the FAQ saves you from the "why is there no sound" panic on iPhone.
Common pitfalls
Pasting Morse with single spaces between words — the tool reads a single space as a letter gap, so `... ---` decodes as two letters, not one word. Use `/` between words, e.g. `... --- ...` stays SOS but `.... .. / -.-- --- ..-` needs the slash to split HI from YOU.
Expecting punctuation that ITU never defined. Curly quotes, em dashes, and emoji have no Morse code and get dropped silently. Stick to letters, digits, and the basics like period `.-.-.-` and comma `--..--`.
Cranking WPM to 30 before you can copy 10 by ear. Speed hides errors — at 30 WPM the gap between `E` (`.`) and `I` (`..`) blurs. Drop to 8-12 WPM, master the rhythm, then climb.
Privacy
Everything runs in your browser via the Web Audio API and plain JavaScript — your text and decoded output never touch a server. When you use the share link, the encoded message rides in the URL so the recipient sees the same result, so avoid putting anything private (passwords, secrets) into a link you share. Plain practice text and callsigns are fine.
