Morse code has been carrying messages for nearly two centuries, from telegraph wires to emergency signals. It remains a fascinating and surprisingly practical code to learn. Our free Morse code translator converts text to Morse and decodes Morse back to text instantly — and it can even play your message as audio tones.
What Is Morse Code?
Morse code is a method of encoding text characters as sequences of two signals: short signals called dots (·) and long signals called dashes (−). Developed in the 1830s for the electrical telegraph, it allowed messages to be sent over long distances using simple on/off pulses. Each letter, number, and punctuation mark has its own unique dot-and-dash pattern.
The most famous Morse sequence is SOS — ··· −−− ··· — the international distress signal, chosen because it is simple and unmistakable.
How to Translate Morse Code Online
- Choose a direction — Text to Morse, or Morse to Text.
- Type or paste your message.
- See the translation instantly.
- Play the audio to hear your message as authentic 600 Hz Morse tones.
When encoding, words are separated by a / so the decoder can reconstruct them accurately.
The Morse Code Alphabet
Here are a few common letters to get you started:
- A:
·− - B:
−··· - C:
−·−· - E:
·(the shortest, since E is the most common letter) - O:
−−− - S:
··· - T:
−(the next shortest)
Morse was cleverly designed so that the most frequently used letters have the shortest codes, making messages faster to send.
Common Uses for a Morse Translator
Learning Morse code — Convert words and listen to the audio to train your ear to the rhythm of dots and dashes.
Puzzles and games — Encode and decode secret messages for escape rooms, treasure hunts, and scavenger games.
Education — Demonstrate how information can be encoded in a simple two-symbol system.
Hobby radio — Amateur radio operators still use Morse (CW) to communicate.
Tips for Learning Morse Code
- Learn by sound, not sight. Morse is meant to be heard — use the audio playback to learn the rhythm of each letter.
- Start with common letters. E, T, A, O, and N appear constantly and have short codes.
- Practice your name and short words first before moving on to full sentences.
Frequently Asked Questions
Is the Morse code translator free? Yes — it is free, requires no sign-up, and runs entirely in your browser.
Can it play Morse code as sound? Yes. The tool plays your encoded message as 600 Hz audio tones, so you can hear the dots and dashes.
How do I write a space between words in Morse?
When encoding, words are separated by a forward slash (/), which the decoder uses to rebuild the original spacing.
What is the Morse code for SOS?
SOS is ··· −−− ··· — three dots, three dashes, three dots — the internationally recognised distress signal.
