FAQ
Morse code is a communication system that represents letters and numbers as sequences of short signals (dots) and long signals (dashes). Invented by Samuel Morse in 1837, it was the international standard for telegraph and radio communication. Today it is best known for the SOS distress signal (... --- ...).
SOS is represented as "... --- ..." — three dots, three dashes, three dots. It is the international distress signal used in radio communication. Note that SOS is sent as a continuous sequence without word breaks.
WPM stands for Words Per Minute, a measure of transmission speed based on sending the standard word "PARIS". Beginners typically operate at 5–10 WPM, while experienced operators can reach 25–30+ WPM.
While commercial use has largely ended, Morse code remains popular among amateur radio operators (hams) worldwide. It is also used in some military, aviation, and maritime contexts. Knowing SOS can still be useful in emergencies.
This tool supports the ITU International Morse Code standard: all 26 letters (A–Z), digits (0–9), and common punctuation marks (. , ? ! / @ & : ' " - + ( )). Japanese kana Morse code is a separate standard and is not supported.
