Morse Code

The Morse Code tool translates text into dots and dashes and back, using the International Morse alphabet. Each letter and digit has a fixed sequence, and the tool handles the spacing between letters and words so the result is readable. It is a fun exercise, a historical curiosity, and still a backup signaling method in radio and aviation. Use it to encode a short message, to practice decoding, or to add a themed touch to a project. The tool works locally in your browser. Morse code represents each character as a sequence of short and long signals, with a defined gap between the signals inside a character, a longer gap between characters, and a longer gap still between words. That timing structure is the part people underestimate, because the dots and dashes are easy to write down while the spacing is what makes the result decodable at the other end. The alphabet was designed so that the most common letters in English took the shortest sequences, which is why E is a single dot and T is a single dash, and that efficiency is a neat illustration of encoding for frequency. It remains in use in aviation and maritime contexts as a backup signalling method, and it is a popular exercise for learning about encoding, radio, and the history of communication. Practically, a message should stay short, and starting with a single word or a callsign lets you confirm you can both encode and decode before moving on to a full sentence. The tool handles the letter and word spacing so the output is unambiguous, and it runs locally in the browser.
