What is Morse code?

Morse code encodes letters and numbers as sequences of short and long signals (dots "." and dashes "−"). Letters within a word are separated by a single space; words are separated by / or three spaces. This tool supports A–Z, 0–9, and common punctuation marks.

How to use

To encode: type plain text and click Text → Morse.
To decode: paste Morse code (e.g. ... --- ...) and click Morse → Text.
Word breaks use / when encoding; use the same separator when decoding.
