Morse code translator

Type text to hear it, see it and print it in Morse code, or paste dots and dashes to read them.

Tap Morse yourself

Hold the key with the mouse, a finger or the Space bar. A press shorter than 160 ms is a dot, a longer one a dash. A pause of 240 ms ends a letter and 560 ms ends a word (15 WPM, from the speed setting).

What is Morse code?

Morse code writes letters, numbers and punctuation as short and long signals: dots and dashes. Because it needs only two states, it can be sent as sound, light, taps or radio pulses.

It was developed in the 1830s and 1840s for the electric telegraph and is named after Samuel Morse. The version used today is International Morse code.

How Morse code is timed

A dash lasts as long as three dots. Between the dots and dashes of one letter there is a gap of one dot, between letters a gap of three dots, and between words a gap of seven dots.

Written down, dots are . and dashes are -, with a space between letters and a slash between words. The translator above also reads · and – when you paste them.

Example: HELLO

Each letter of HELLO has its own pattern. Put them in order with a space between them:

  1. H
  2. E
  3. L
  4. L
  5. O

Result: .... . .-.. .-.. ---

To read it back, split the code at the spaces and look every pattern up in the chart.
