Morse Code TranslatorAbout Morse Code Translator
Morse Code Translator is a free set of tools for turning text into Morse code and back. You can hear it, see it as light, feel it as vibration, save it as a sound file and decode it from a microphone or an audio file.

How we check the codes
- Letters, figures, punctuation and service signals come from Recommendation ITU-R M.1677-1, the international Morse code standard.
- A few signs that people use but that are not in the ITU list (! & ; _ $) are marked as "not ITU" on the alphabet page.
- Timing follows the ITU spacing rules: a dash is three dots, the gap inside a letter is one dot, between letters three dots, and between words seven dots.
- Prosigns and learning tips follow the ARRL, the national association for amateur radio in the US.
How we test
All code tables and the decoder live in one file that is checked by automated tests before every release. The tests turn every ITU sign into Morse and back, check that the word PARIS lasts exactly 50 dot lengths, and play test messages at different speeds and tones with added noise into the audio decoder to make sure it reads them back correctly.
What we do not do
We do not track what you type, and the microphone audio never leaves your device. See our privacy policy.
