Text to Morse

Just type letters, numbers and punctuation into the top box and the Morse code will appear in the bottom box, with a "#" inserted if the character cannot be translated.

Morse to Text

You can type American Morse code into the top box using "." for a dot and "-" or "_" for a dash. The long-dash for an "L" is Unicode U+2E3A ("⸺") and the even longer dash for a zero is Unicode U+2E3B ("⸻"). Use a single space within a letter (such as a "C" which is ".. ."). Letters are separated by three spaces and words by "/" or "|". The plain text translation will appear in the bottom box. If a letter cannot be translated a "#" will appear in the output.

Sound, Light & Vibration

The "play", "pause", "stop" and "loop" buttons control the playback. You can choose between hearing the sound, seeing a flashing light, or having your phone vibrate using the "Sound", "Light" and "Vibrate" checkboxes. The vibrate option may only appear on a phone. There are also advanced options to control the pitch and speed. The "Farnsworth speed" is useful when learning Morse code as it can be set lower than the other speed in order to stretch out the spaces between characters and words whilst keeping the Morse characters fast.


To produce the sounds, in the latest versions of Chrome, Firefox, Safari and Edge the translator uses the Web Audio API and require Javascript to be enabled. Internet Explorer does not support the Web Audio API and so Flash must be installed and enabled (Flash often has security issues though so is best avoided). The download button will download the audio as a wav file. In Safari you must hold the Option key when clicking the download button and give the file a name ending in ".wav".
