Quick answer: Type in the Text box to get Morse code, or type dots and dashes in the Morse code box to get text. Put a space between letters and a slash (/) between words.
How to use the Morse code translator
- Text to Morse code: type or paste in the left box. Letters, numbers and common punctuation are converted instantly.
- Morse code to text: type in the right box using
.for dot and-for dash. Separate letters with one space and words with/. Codes that don’t exist show as#. - Hear it: press Play sound. 15 words per minute is a comfortable listening speed; beginners often start at 5 to 10.
- Copy: use the copy buttons to paste the result into a message or document.

Morse code timing rules
International Morse code is built on one unit of time, the length of a dot:
- A dot is 1 unit, and a dash is 3 units.
- The gap between dots and dashes inside a letter is 1 unit.
- The gap between letters is 3 units, and between words 7 units.
At 15 words per minute one unit is 80 milliseconds. Speed is measured with the word “PARIS”, which is exactly 50 units long including the space after it. The sound player follows these rules exactly.
A short history of Morse code
Samuel Morse and Alfred Vail developed the code for the electric telegraph in the 1830s and 1840s. The version used today, International Morse code, was standardized in 1865 and is now maintained by the International Telecommunication Union. Ships used it for distress calls until 1999. Amateur radio operators still use it daily, because a simple Morse signal gets through when voice can’t. SOS (... --- ...) was chosen because it is easy to send and recognize, not because it stands for any words.

Why is there no sound?
Check that your device isn’t muted. On iPhone, the silent switch can block web audio. The light still flashes without sound.
Can I convert Morse code to binary?
Not directly. For computer code, use our binary translator.
