Convert text to Morse code and decode Morse to text. Learn and practice Morse code with audio playback.
This converter translates in both directions: it turns ordinary text into International Morse Code and decodes Morse back into readable text. It covers the full alphabet, the digits 0 through 9, and common punctuation, with word boundaries represented by the standard slash and letters separated by spaces. Conversion runs live as you type, entirely in your browser. For learners, the audio playback renders your Morse as a 600 Hz tone (the customary practice pitch) with the correct three-to-one dash-to-dot timing at slow, normal, or fast speed, and the reference chart above doubles as a study aid while you practice copying by ear.
Morse code was developed in the 1830s by Samuel F. B. Morse and Alfred Vail to carry messages over the new electric telegraph, with the famous first public message sent in 1844. Its genius is efficiency: the shortest symbols go to the most frequent English letters, so E is a single dot while rare letters like Q and Z earn longer patterns. Although the telegraph era is long past, Morse still serves in amateur radio, navigation beacon identification, and the internationally recognized SOS distress signal (... --- ...), and it can be signaled with nothing more than a tone, a flashlight, or taps on a pipe.
If you enjoy encoding formats, the Text to Binary converter shows how computers represent the same characters, and the Case Converter handles everyday text transformations.
Morse code was developed in the 1830s by Samuel F. B. Morse and Alfred Vail for sending messages over the electric telegraph; the first public message traveled in 1844. While the telegraph is gone, the code lives on in amateur radio, navigation beacon identifiers, and as the internationally recognized SOS distress signal, and hobbyists still learn it for both fun and emergencies.
Each letter is written as dots and dashes with spaces between the symbols, and a full word boundary is written as a slash. For example, SOS is written as three separate letter groups: ... --- ... . This converter inserts the letter spaces automatically when encoding and expects dots and dashes separated by spaces when decoding.
A dash lasts exactly three times as long as a dot, which is what gives Morse its rhythm. The audio playback in this tool reproduces that ratio with a 600 Hz tone, the standard practice frequency, and offers slow, normal, and fast speeds so you can train your ear progressively as you learn.
Yes. It supports the letters A through Z, the digits 0 through 9, and common punctuation including periods, commas, question marks, slashes, parentheses, colons, and the at sign. Any character without a Morse equivalent, such as an accented letter, passes through to the output unchanged.
Beyond its historical charm, Morse code remains practical: amateur radio operators use it for long-distance contacts where voice fails, the simplicity of a single tone makes it usable with minimal equipment or even light blinks in survival situations, and learning it is a rewarding exercise in rhythm and listening. The reference chart and audio playback on this page make self-study straightforward.
