Morse Code Translator
Morse code turns letters, numbers and punctuation into short and long signals, the dot and the dash. It was built for the telegraph in the 1830s and 40s, and it is still used today by pilots, sailors, amateur radio operators and anyone who needs a message to get through when voice will not.

How the Morse Code works
Each letter maps to a unique run of dots (short) and dashes (long). A single space separates letters, and a forward slash separates words, which keeps a decoded message readable.
The most common letters get the shortest codes: E is a single dot and T is a single dash. That frequency-based design let skilled operators send everyday English remarkably fast.

History and origins
Samuel Morse and Alfred Vail developed the code in the United States, first sending a public message over a telegraph line in 1844. The original American Morse was later refined into International Morse Code, standardised in 1865, which is the version used almost everywhere now and the one this translator uses.
Long after voice radio arrived, Morse survived because it is simple, cheap and robust. A faint signal that would be unintelligible as speech can still be copied as clean dots and dashes, which is why distress and identification signals leaned on it for over a century.
Frequently asked questions
How do I write SOS in Morse code?
SOS is three dots, three dashes, three dots: ... --- ... . It was chosen because the pattern is short, symmetrical and unmistakable, not because the letters stand for anything.
Can this translator play Morse code as sound?
Yes. Encode any text and press play to hear it beeped out at a speed you can adjust, which is the fastest way to start training your ear.
What separates letters and words in Morse code?
A gap of one space separates letters and a forward slash separates words in this tool. When sending by sound or light, the gap between words is about seven dot-lengths.
Is Morse code still used today?
Yes. Amateur radio operators use it daily, aviation beacons identify themselves in Morse, and it remains a reliable fallback when bandwidth or signal strength is poor.
