Morse信号変換

This Morse code translator converts text to Morse and Morse back to text, using the international (ITU) standard, with a one-tap swap to switch direction.

Morse code represents each letter and digit as a sequence of dots and dashes. It was the backbone of early telegraph and radio communication and is still used in aviation, amateur radio and as an accessible signaling method.

The most famous sequence, SOS, is three dots, three dashes, three dots. Morse has no upper and lower case, so encoding gives the same result however you type, and decoded text is shown in lower case.

In the output, letters are separated by a single space and words by a slash. When decoding, the tool is forgiving and also accepts a larger gap between words, so pasted Morse from different sources still works.

It supports all letters, digits and the common punctuation of the international standard. Characters that have no Morse representation are simply skipped rather than producing an error.

It is handy for learning Morse, solving puzzles or decoding a message, and runs entirely in your browser.
