Morse Code Translator

Morse code is a way of representing letters, numbers and punctuation as sequences of short and long signals, written as dots and dashes. A dot is a short signal and a dash is a long one. It was developed in the 1830s and 1840s for the electric telegraph and later used widely in radio. Each character has its own unique pattern, so SOS is three dots, three dashes, three dots.

SOS is ... --- ..., which is three dots for S, three dashes for O, and three dots for S again. It is the best known Morse signal because it is simple to send and recognise, and it was adopted as the international distress call. Type SOS into this translator with Text to Morse selected and you will see exactly that.

Within a word, the letters are separated by a single space. Between words, the standard separator is a forward slash with a space on each side, written as / so the gap is clear. For example HI THERE becomes .... .. / - .... . .-. . , where the slash marks where one word ends and the next begins. This translator uses that convention both ways.

Yes. The translator covers the letters A to Z, the digits 0 to 9, and common punctuation such as the period, comma, question mark, slash and others from the standard international Morse alphabet. Each has its own dot-and-dash pattern. A character that has no Morse equivalent is simply left out of the result so the output stays clean.

Read each group of dots and dashes as one character, using a Morse chart, then leave a gap between letters and a longer gap (the slash here) between words. With practice, common letters like E (one dot) and T (one dash) become quick to recognise. The easiest way is to paste the Morse into this tool with Morse to Text selected and let it decode the message for you.

Yes, in a few places. Amateur (ham) radio operators still use it because a Morse signal can get through when voice cannot, and aviation navigation beacons identify themselves in Morse. It is also taught as a useful skill and used in puzzles and games. It is no longer the main way messages are sent, but it remains a reliable, low-bandwidth method that many people enjoy learning.
