How does Morse code work?

International Morse Code maps each letter, digit, and common punctuation mark to a sequence of dots and dashes. This translator uses a lookup table: each character you type emits the corresponding pattern, separated by single spaces between letters and three spaces between words. Letters with no Morse mapping show as a question mark. Type Morse in the reverse direction and the process inverts.

This tool uses International Morse Code. As you type in the text box, each character is looked up in a table and the corresponding Morse pattern is emitted, separated by single spaces between letters and three spaces between words. Type Morse in the lower box and it reverses the process.

Supported: letters A–Z (case-insensitive), digits 0–9, and punctuation: . , ? ' ! / ( ) & : ; = + - _ " $ @

Privacy: nothing you type is sent anywhere. The translator runs entirely in your browser via a small JavaScript file.
