How to translate Morse code
- Type text in the left box to get Morse code, or type or paste Morse code in the right box to decode it. Use
.and-, a space between letters and/between words. - Press Play sound to hear it as beeps, or Flash light to see it as light signals. Adjust the speed in words per minute and the tone.
- Open the chart to look up any letter, number or punctuation mark.
About Morse code
Morse code was developed in the 1830s and 1840s by Samuel Morse and Alfred Vail for the electric telegraph, and the international version used today was standardised in 1865. Each letter is a short sequence of dots (short signals) and dashes (long signals): E, the most common English letter, is a single dot. The most famous signal, SOS (... --- ...), was chosen as a distress call because it is easy to send and recognise.
The timing follows the international standard: a dash is three dots long, the gap between parts of a letter is one dot, between letters three dots and between words seven dots. Speed is measured in words per minute using the word "PARIS" as the reference. Beginners usually learn at 15–20 WPM with extra spacing (the Farnsworth method) so they learn the sound of whole letters rather than counting dots.
Morse is still used by amateur radio operators, in aviation and marine navigation beacons, as an accessibility input method, and in puzzles and escape rooms. Everything here runs in your browser.
What is SOS in Morse code?
... --- ... (three dots, three dashes, three dots), sent as one continuous signal.
How do I separate words in Morse code?
Use a slash with spaces around it ( / ). Three or more spaces also work when decoding.
Can it translate accented letters?
Accents are removed (é becomes E) because international Morse has no separate codes for most accented letters.
