Convert text to Morse code, or decode dots and dashes back to letters. Letters are separated by spaces and words by a slash. Free, private, and runs entirely in your browser.
Every letter, digit and common punctuation mark has a pattern of short signals (dots) and long signals (dashes). The translator looks up each character, and in decoding mode splits your input by spaces and slashes and looks up each group.
| Letter | Code | Letter | Code |
|---|---|---|---|
| A | .- | N | -. |
| B | -... | O | --- |
| C | -.-. | P | .--. |
| D | -.. | Q | --.- |
| E | . | R | .-. |
| F | ..-. | S | ... |
| G | --. | T | - |
| H | .... | U | ..- |
| I | .. | V | ...- |
| J | .--- | W | .-- |
| K | -.- | X | -..- |
| L | .-.. | Y | -.-- |
| M | -- | Z | --.. |
Digits: 0 = -----, 1 = .----, 2 = ..---, 3 = ...--, 4 = ....-, 5 = ....., 6 = -...., 7 = --..., 8 = ---.., 9 = ----..
How do I write a space in Morse? Use a space between letters and a slash between words. On the air the gap lengths do this job.
What is SOS in Morse? It is three dots, three dashes and three dots, written ... --- ... as one signal with no gaps between the letters.
SOS Figuro becomes ... --- ... / ..-. .. --. ..- .-. --- . Decoding goes the other way: ... --- ... returns SOS.
Does Morse code have lowercase letters? No. Morse does not distinguish case, so the translator reads both the same.
Which characters are supported? Letters, digits and common punctuation such as . , ? ! / ( ) & : ; = + - _ " $ @.
Morse code was developed in the 1830s and 1840s by Samuel Morse and Alfred Vail for the electric telegraph, and the first long-distance message, What hath God wrought, was sent on May 24, 1844. The version used today is International Morse code, which was standardized internationally in the 1860s and is still used in amateur radio, aviation beacons and as an accessibility input method.
Use this translator to learn Morse, to prepare puzzles or escape-room clues, or to send a message with a flashlight or tap. Type the text, copy the dots and dashes, and use the chart above to practice decoding by hand.
Is Morse still used today? Yes. Amateur radio operators, some navigation beacons and accessibility devices still use it.
Can I hear the code? This tool shows the written code. Read the dots as short sounds and the dashes as long sounds.
