International Morse code chart
Press a character to hear it.
This uses International Morse code (ITU): the letters A to Z, the digits and common punctuation. Letters are separated by a space and words by a slash. Accented letters and characters with no Morse code are left out of the translation, and the note under the box lists them. Timing follows the standard PARIS word: at 20 words per minute a dot lasts 60 milliseconds. Sound is generated in your browser and nothing is sent anywhere.
How to use it
- Type text in the left box to see it in Morse code, or type dots and dashes in the right box to read them as text.
- Separate letters with a space and words with a slash when writing Morse.
- Press Play Morse to hear it and watch the light flash, and adjust the speed and tone.
- Use the chart below to look up or hear any character.
Questions
How do I write Morse code here?
Use a full stop for a dot and a hyphen for a dash. Put a space between letters and a slash between words, for example .... .. / - .... . .-. .
What does WPM mean?
Words per minute, measured with the standard word PARIS, which is 50 dot lengths long. At 20 WPM a dot lasts 60 milliseconds, a dash three times as long.
What is SOS in Morse code?
Three dots, three dashes, three dots: ... --- ... It is sent as one continuous signal without the usual gaps between letters, and was chosen because it is easy to recognise.
Why are some characters missing?
International Morse has no codes for most symbols, emoji or accented letters. They are skipped and listed under the text box so you know what was left out.
About this tool
About the Morse code translator
Morse code writes each letter as a short pattern of dots and dashes. It was built for the telegraph and is still used by radio amateurs, pilots checking navigation beacons and anyone who needs a signal that works with a torch or a tapping finger.
Type text in one box and the Morse appears in the other; type dots and dashes and the text appears instead. Letters are separated by spaces and words by a slash, the usual written convention.
- Hear it: play the code as a tone, with the speed adjustable from 5 to 40 words per minute and the pitch from 300 to 1000 hertz.
- See it: a light flashes in time with the sound, or on its own if you switch the sound off.
- Learn it: the chart lists every letter, digit and punctuation mark, and each one plays when you press it.
The translator follows International Morse code, with timing based on the standard word PARIS. Characters that have no Morse code, such as emoji or most accented letters, are left out and listed so nothing is lost silently. Everything happens in your browser.
