Morse Code Translator
Convert standard plain text into international Morse code (dots and dashes) and decode it back in real-time.
Morse Quick Guides
Letters are separated by a single space (e.g. H = ...., I = .. is .... ..). Words are split by a triple space ( ) or a forward slash (/).
A dash is exactly three times the length of a dot. Spacing between dots or dashes in a single letter equals one dot length.
