🔍Morse Code🔒 100% local

Converts between plain text and International Morse code, deciding the direction from what is in the box: input made only of dots, dashes, spaces and slashes is decoded, and anything else is encoded. Letters are separated by a single space and words by a slash. The table covers A to Z, the ten digits and about twenty punctuation marks, and a character outside it comes back as the Unicode replacement character.

How to use it

1. Type text such as SOS, or paste Morse such as ... --- ...
2. Press Process, then read the result in the output box.
3. Press Copy Output. Round-tripping your own output is the quickest way to check a message you were given.

Worked example

When to use it

• Encoding a message for a puzzle, a card or a treasure-hunt clue.
• Checking a Morse string you received against the standard letter table.
• Producing a short encoded string for a design mock-up.

What it does not do

• The direction is guessed from the characters present, so a run of only dots and dashes is always decoded. Two hyphens meant as text come back as the letter M rather than being encoded.
• Unknown characters are substituted silently, which is easy to miss inside a longer string.
• Word breaks are recognised only as two or more spaces or a spaced slash, so ordinary single-spaced Morse decodes as one long word.
• There is no audio and no timing here; the separate morse-code-synthesizer tool adds a duration estimate and a unit count.
• Prosigns such as SK and AR, accented letters and emoji are not supported, and an unrecognised code group decodes to the replacement character instead of being reported.
