Morse Code Translator
Text to Morse, Morse to text — and hear the signal played back like a real operator.
SOS, secret messages, ham radio practice or plain curiosity: Morse code still fascinates, a century and a half after Samuel Morse. Type your text and the dots and dashes appear instantly — or paste Morse code and get the text back, the tool detects the direction on its own. The full international alphabet is supported: letters, digits and punctuation, with accented letters folded to their plain form. Best of all, you can listen to your message: a play button sounds the beeps through your speakers, with a speed adjustable from 5 to 25 words per minute — ideal for training your ear. Free, no sign-up, and it all happens right on the page.
How does it work?
- Type or paste your text — or Morse code; the direction is detected automatically.
- The translation appears live: one space between letters, “/” between words.
- Click “Play” to hear the message as beeps, and adjust the speed in words per minute.
- Copy the result with one click.
Frequently asked questions
What is SOS in Morse code?
SOS is “... --- ...”: three dots (S), three dashes (O), three dots (S). It was adopted in 1906 precisely because it is easy to send and impossible to mistake, even through heavy interference. Contrary to legend, it is not an acronym — “Save Our Souls” was invented after the fact.
How do dots, dashes and spaces work?
Everything is built on one time unit: a dot lasts 1 unit, a dash 3. Within a letter, signals are separated by 1 unit of silence; between letters, by 3; between words, by 7. That is exactly the rhythm this tool's audio playback reproduces, using a 600 Hz tone close to what real radio keyers sound like.
Is Morse code still used today?
It stopped being mandatory at sea in 1999, but it is very much alive among ham radio operators, in aviation — navigation beacons identify themselves in Morse — and as a last-resort channel: it gets through where voice cannot, with a flashlight, a whistle or a single tone.
What is the best way to learn Morse code?
By ear, not by sight: operators recommend the Koch method — listen to characters at your target speed and add new ones gradually. Write short words, play them here at a slow setting (5-10 wpm), then speed up. Recognising each letter's rhythm comes surprisingly fast.
