Morse Code Translator & Decoder

What is Morse code?

Dots represent short signals and dashes represent long ones. A is written as .-, while N is -.. This is an encoding system, not encryption: it changes the form of a message without making the words secret. Under the ITU timing rules, a dash lasts three dot units, letters are separated by three units and words by seven.

Enter ordinary text in the first tab to produce a sequence for each supported letter, digit or punctuation mark. Uppercase and lowercase input give the same result. The character list beneath the output makes an unsupported symbol visible instead of silently treating it as a valid signal. Playback follows the dot-dash rhythm; copying and sharing use the same displayed result. Conversion happens in your browser.

Decode by keeping the separators

To translate Morse code back to text, put one space between letter groups and a slash between words. For example, ... --- ... becomes SOS, while .... .. becomes HI. A missing space can turn two intended letters into a different pattern, so check the separators first when the output contains [?] or an unexpected character.

The alphabet used here follows the international A-Z set, digits and common punctuation. Its history began with Samuel Morse and Alfred Vail's telegraph work; the code later changed before reaching the international form used as today's reference.
