Morse Code Translator Online - Free Text to Morse Converter
Morse code, invented by Samuel F. B. Morse in 1837, is a method of encoding text using short dots (·) and long dashes (—) with pauses. It was the backbone of early telegraphy and remains in use today by amateur radio operators, pilots, sailors, survivalists, and in movies/escape rooms. The universal distress signal SOS (··· ——— ···) is the most famous Morse code sequence.
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes.

Use finger taps, flashlight switches, or whistle blasts:
Short (·) → Quick tap "dit"
Long (—) → 3× longer "dah"
1-second pause between letters, 3-second between words
Remember these for emergencies:
E = · (one dit)
T = — (one dah)
A = ·— (dit-dah)
I = ·· (dit-dit)
M = —— (dah-dah)
S = ··· (dit-dit-dit)
O = ——— (dah-dah-dah)
→ SOS distress signal = ··· ——— ···
Practical: dit-dit-dit dah-dah-dah dit-dit-dit (send continuously, understood worldwide!)
Practice 10 times and you'll know the international distress signal!
