How it works
International Morse code encodes each letter and digit as a sequence of dots (short) and dashes (long). It was standardized in 1865 for telegraphy; the most common letter in English, E, gets the shortest code — a single dot — which keeps messages compact.
Timing matters in real transmission: a dash lasts three dots, the gap between symbols is one dot, between letters three dots, and between words seven. In written form this tool uses spaces between letters and " / " between words, the standard convention.
Worked examples
SOS: "SOS" becomes "... --- ..." — the most recognized distress signal in the world.
Decode: Paste ".... . .-.. .-.. ---" to decode it back to "HELLO".
