Morse Code Translator

Morse code is a method of encoding text as sequences of short signals (dots) and long signals (dashes). Each letter, digit and some punctuation marks map to a unique pattern — for example S is three dots (…) and O is three dashes (———). It was designed for telegraphy and is still used in radio communication today.

Type or paste your text or Morse into the input box above. MorseAtlas detects the direction automatically: plain text becomes Morse, and dots-and-dashes become readable text. You can also force a direction with the mode buttons.

A single space separates letters, and a slash surrounded by spaces ( / ) separates words. For example, "SOS" is written "... --- ..." while "I LOVE YOU" is ".. / .-.. --- ...- . / -.-- --- ..-". MorseAtlas accepts several input styles, including slashes without spaces and underscores as dashes.

Yes. Press Play to hear the signal as a clean tone. You can adjust the speed (WPM), pitch in hertz and volume in the settings under the translator. The same timing powers WAV download and the screen-flash option.

No. All translation and audio processing happens locally in your browser. Nothing you type or record is sent anywhere — you can even use the translator offline once the page has loaded.

20 WPM is the common default and a good starting point. Slower speeds like 10–15 WPM are easier when you are learning to copy by ear; faster speeds sound more like real radio traffic. Speed follows the standard PARIS timing: one dot equals 1200 divided by WPM milliseconds.
