Morse code was invented by Samuel Morse in the 1830s to transmit messages over telegraph wires. Each letter and digit is encoded as a sequence of short signals (dots) and long signals (dashes). It remains in use in aviation, amateur radio, and accessibility contexts where other communication methods are unavailable.
Frequently asked questions
How do I enter Morse code to decode?
Type or paste Morse code in the right box using dots (.) and dashes (-) with spaces between letters and a forward slash (/) between words. Then click Morse → Text.
What is SOS in Morse code?
SOS is · · · − − − · · · (three dots, three dashes, three dots). It was chosen as a distress signal because it is easy to transmit and recognize, not because the letters S-O-S stand for anything specific.
