Morse Code Translator

Morse code turned the alphabet into a series of dots and dashes that could travel down a telegraph wire, and later through radio and light. Invented in the 1830s–40s, it is still used in aviation, amateur radio, and as a fallback signalling method — and it remains a fun code to learn.

How it works

Each letter, digit, and common punctuation mark maps to a unique sequence of short signals (dots, ·) and long signals (dashes, −). E is a single dot, T a single dash — the most common letters get the shortest codes, which made transmission efficient. This tool uses the international Morse standard.

Encoding and decoding

Switch between two modes: type text to get Morse, or paste Morse to get text back. When decoding, separate letters with a single space and words with a forward slash (/), which is the conventional way to mark word boundaries in written Morse.

The famous SOS

The best-known Morse signal is SOS: · · · − − − · · ·. It was chosen as an international distress call precisely because the pattern is simple, symmetrical, and impossible to confuse with anything else.
