Morse Code Translator & Decoder

morsedecoder converts English to International Morse code and decodes Morse back to text in real time. Letters are separated by a single space and words by a slash (/), following the ITU-R M.1677 standard where a dash lasts three times as long as a dot. Everything runs client-side, so your text never leaves the browser.

For example, HELLO WORLD becomes.... . .-.. .-.. --- / .-- --- .-. .-.. -.., and the distress call SOS is ... --- .... Use the example chips to load common phrases, press Play to hear the rhythm, andCopy or Share the result.

• Type or paste English text or Morse into the box. The tool auto-detects the direction — dots, dashes, spaces and slashes read as Morse; anything else reads as text.
• Read the result instantly in the second box, thenCopy, Share a link, Play the sound, or download a WAV.
• Switch input mode with the Text and Audio tabs to decode typed Morse or clear single-tone beeps.

More than text: Morse audio

The Audio tab plays Morse as clean beeps and decodes uploaded files or mic recordings — see theaudio translator. Everything runs in your browser, with nothing uploaded.

Most decoding errors come from spacing. Keep the rhythm clean and the result is exact:

• One space between letters. .... . is HE; running them together as ..... with no gap is read as a single unknown group.
• A slash (/) between words. HI / THERE, not HI THERE — a missing slash merges two words into one.
• Only dots, dashes, spaces and slashes. Letters like O instead of a dash, or commas between symbols, will not decode.

Punctuation is supported when going from text to Morse — period .-.-.-, comma --..--, question mark..--.., slash -..-. and more follow the ITU standard. Unsupported characters (most emoji and non-Latin letters) are flagged with a warning instead of being silently dropped. See the fullMorse code chart for every letter, number and mark.
