Morse Code Translator

What Is the Morse Code Translator?

It converts text to International Morse code - dots and dashes - and Morse code back to text. It can also play the code as sound at a speed you choose, so you can hear what a message sounds like or practise listening.

How Morse Code Is Written

Each letter and digit has its own pattern of short signals (dots, .) and long signals (dashes, -). This tool separates letters with a space and words with a slash, the most common way to write Morse in text.

How to Use It

1. Type text to see the Morse code, or paste Morse code to decode it.
2. Choose a playback speed and tone, then click Play Sound.
3. Copy the code.

Example

SOS at 9pm becomes ... --- ... / .- - / ----. .--. --. SOS is three dots, three dashes and three dots; the digit 9 is four dashes and a dot. Morse has no lowercase, so decoding gives SOS AT 9PM.

Timing and Speed

Playback follows the standard timing: a dash is three times as long as a dot, the gap between letters is three dots long and the gap between words is seven. Speed is measured in words per minute using the standard word "PARIS"; 15 words per minute is a comfortable speed for most learners.

Limitations

The tool uses International (ITU) Morse code for the letters A-Z, digits and common punctuation. Accented letters, non-Latin scripts and prosigns are not included; characters without a code are skipped and listed below the buttons. Sound needs a browser that supports the Web Audio API. To spell words out loud on the phone, the NATO Phonetic Alphabet Converter is easier to follow.
