Morse Code Chart
Free Morse Code Translator
Two-way conversion, audio playback and the full chart
The Morse code translator turns your text into dots and dashes and decodes Morse code back into readable text. In auto mode it detects whether you typed text or Morse; letters are separated by spaces and words by a slash. Letters, digits, punctuation and common accented characters are supported. The Play button sounds the code with Web Audio at a 700 Hz tone, and you can set the speed in words per minute (WPM). The chart at the bottom lists every letter and digit. Everything runs in your browser.

Morse Rules
Timing
- Dot: 1 unit · Dash: 3 units
- Gap within a letter: 1 unit · Between letters: 3 units
- Between words: 7 units (written as /)
- Unit length = 1.2 ÷ WPM seconds
Well-known codes
- SOS: ··· −−− ···
- E is the shortest letter (·), T a single dash (−)
- Digits use 5 symbols: 1 = ·−−−−, 0 = −−−−−
- Developed by Samuel Morse and Alfred Vail in 1837
Frequently Asked Questions
How do I read Morse code?
Each letter is a sequence of dots (short) and dashes (long); letters are separated by spaces and words by a longer gap or a slash. For example ··· −−− ··· = SOS.
Which characters are supported?
A–Z, 0–9, common punctuation and accented letters such as É, Ñ, Ä, Ö, Ü and Ç. Unknown symbols are skipped.
How should I type Morse code?
Use . or · for dots, - or − for dashes, a space between letters and / between words.
How does audio playback work?
The Play button sounds the code as a 700 Hz sine tone; the WPM value sets the speed (15 WPM is a good start).
What does SOS stand for?
Nothing: the easily recognised ··· −−− ··· pattern was adopted as the international distress signal in 1906.
