Morse code is a method of encoding text characters using sequences of dots (short signals) and dashes (long signals). Invented by Samuel Morse in the 1830s, it was originally used for telegraph communication. Each letter and number has a unique pattern — for example, SOS is ··· ——— ···.

How does Morse code timing work?

In standard Morse code, a dash is three times the length of a dot. The gap between parts of the same letter equals one dot length. The gap between letters is three dot lengths, and the gap between words is seven dot lengths. Speed is measured in words per minute (WPM), where one "word" is the standard word PARIS.

Is Morse code still used today?

Yes, Morse code remains in use by amateur radio operators, aviation (for navigation beacons), and the military. The universal distress signal SOS (··· ——— ···) is recognized worldwide. It is also used as an assistive communication method by people with disabilities.

How do I translate text to Morse code online?

Type or paste your text into the input field of this Morse code translator. The tool instantly converts every letter and number into its Morse code equivalent using dots and dashes. You can then copy the result or play it as audio. For other text encoding formats, try the [Text to Binary Converter](/text-to-binary) or [Hex to ASCII Converter](/hex-to-ascii).

What is SOS in Morse code?

SOS in Morse code is ··· ——— ··· (three dots, three dashes, three dots). It was adopted as the international distress signal in 1906 because the pattern is easy to transmit and recognize. Despite popular belief, SOS does not stand for "Save Our Souls" — it was chosen purely for its simplicity.

Can I hear Morse code audio in this translator?

Yes. Click the Play button to hear your Morse code as audio beeps generated by the Web Audio API. You can adjust the playback speed using the WPM (words per minute) slider — lower values are easier to follow for beginners, while experienced operators may prefer 20+ WPM.
