Translate between text and Morse code with audio playback.
Our free Morse Code Translator converts text to Morse code and Morse code back to text instantly. Type in either direction, listen to the audio playback of your message, and reference the complete character chart — all in one tool, right in your browser.
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 by Samuel Morse and Alfred Vail for use with the electric telegraph, it became the first widely used form of long-distance electronic communication.
Each letter, number, and punctuation mark has a unique Morse code sequence. For example, the letter A is ".-" (dot-dash), while S is "..." (three dots) and O is "---" (three dashes). The famous SOS distress signal is "... --- ..." — three dots, three dashes, three dots — chosen because it's easy to recognize and transmit even under stress.
While Morse code is no longer used for mainstream communication, it remains relevant in amateur (ham) radio, aviation, military signaling, and as an accessibility tool for people with limited mobility who can communicate using a single switch.
The translator works in both directions simultaneously. Here's how to use each mode:
When entering Morse code manually, use a single space between each letter's code and a forward slash (/) surrounded by spaces to separate words. For example, "HELLO WORLD" in Morse would be: .... . .-.. .-.. --- / .-- --- .-. .-.. -... Getting the spacing right is essential for accurate decoding.
To learn Morse code effectively, start with the most common letters in English: E (.), T (-), A (.-), and N (-.). These four letters appear most frequently in text, so learning them first gives you the most immediate payoff. Practice by translating short, common words before moving on to full sentences.
The audio playback feature is excellent for training your ear to recognize Morse code by sound rather than by sight. Listen to the playback repeatedly while following along with the dots and dashes on screen. Over time, you'll start to recognize common letter patterns by their rhythm alone.
This translator handles both encoding and decoding in real time, so you don't need to switch between separate tools. The bidirectional conversion means you can use it as a learning aid — type a word, see its Morse code, then try to type the Morse code yourself and verify your answer.
The audio playback uses the Web Audio API to generate accurate dot and dash tones at the correct timing ratios (a dash is three times the length of a dot, and the gap between letters is three dot-lengths). This makes it suitable for actual Morse code practice, not just visual reference.
The complete reference chart at the bottom of the tool covers all 26 letters and 10 digits, making it a handy quick-reference guide even if you're not actively translating anything.
