About this tool

The Morse Code Translator converts plain text into Morse code — the dot-and-dash telegraphic alphabet dating back to the 1830s — and decodes Morse code back into readable text. Letters within a word are separated by a single space, and words are separated by a forward slash, following the standard convention used in Morse code references and puzzles.

The full International Morse Code alphabet is supported: all 26 letters, digits 0-9, and common punctuation (period, comma, question mark, and more). Unsupported characters are skipped with a clear notice rather than silently corrupting the output, so you always know exactly what was and wasn't translated.

An optional "Play audio" toggle renders the Morse code as actual beep tones using the Web Audio API — a short beep for each dot, a longer beep for each dash, with appropriately timed silences between letters and words — so you can listen to and practice real Morse timing rather than just reading dots and dashes on screen.

Common uses: amateur radio (ham radio) practice, puzzle and escape-room hobbyists, historical curiosity, and CTF/puzzle challenges that hide a message in Morse code. Everything runs entirely in your browser — no text or audio ever leaves your tab.

FAQ

How are letters and words separated in the output?

Letters within a word are separated by a single space. Words are separated by a forward slash ( / ) surrounded by spaces, which is the standard convention used in most Morse code references and decoders.

What happens with characters that have no Morse equivalent?

They are skipped, and a notice lists exactly which characters were unsupported, so the rest of the message still translates correctly and you know precisely what was left out.

Does the audio playback use real Morse timing?

Yes — dots are short beeps, dashes are three times as long, and the silences between letters and words follow the standard proportional timing convention, so the audio sounds like authentic Morse code rather than an arbitrary beep pattern.

Are numbers and punctuation supported, not just letters?

Yes. Digits 0-9 and common punctuation (period, comma, question mark, apostrophe, and several others) all have defined Morse sequences and are fully supported in both directions.

Is Morse code still used today?

Its practical telegraphic use has largely disappeared, but it remains part of amateur (ham) radio licensing and operation, is used in some aviation and maritime identification signals, and persists culturally in puzzles, distress signaling (SOS), and hobbyist communities.
