Tap to stop
Shows the full Morse code chart: 26 letters, 10 digits and punctuation, with Cyrillic, Wabun and Korean tables one tap away. Tap any sign to hear it at your chosen speed. Learn by sound rather than by counting dots: E (.), T (-), A (.-) and N (-.) are the best first letters.
How to use
- Type or paste text to get Morse code, or type dots and dashes to get text. The direction is detected automatically – tap the arrow to swap.
- Tap the result to copy it. Letters are separated by spaces and words by a slash ( / ).
- Press Play to hear it, Light to see it flash full screen, or WAV to download the sound.
- Set the speed in words per minute, the tone and Farnsworth spacing (normal-speed letters with longer gaps, ideal for learning).
- Radio feel: add static and fading under Sound settings. They are used for playback and in the WAV file, together with the speed, spacing and tone you chose.
- Keyer: open it and hold Space or the big key to send. Short presses are dots, long ones dashes; pauses end a letter or a word, and the text appears as you key. Follow my speed adapts to your pace.
- Timing follows the PARIS standard: a dot is 1 unit, a dash 3, the gap inside a letter 1, between letters 3 and between words 7.
- Cyrillic letters use the Russian Morse alphabet and Japanese kana use Wabun code. Pick the alphabet before decoding, since the same code can mean different letters.
- Decoding accepts ., ·, •, - , –, — and _ as dots and dashes, and /, | or several spaces between words.
- Light mode flashes the whole screen in time with the sound – handy for signaling.
- In the light view, Flashlight also blinks the phone’s camera light where the browser allows it (mostly Chrome on Android).
How Morse code timing works
Morse code is built from one time unit. A dot (dit) lasts 1 unit and a dash (dah) 3 units; the gap between the parts of a letter is 1 unit, between letters 3 units and between words 7 units. Speed is measured with the standard word PARIS, which is exactly 50 units long, so at 20 words per minute one unit lasts 60 milliseconds (1200 ÷ WPM).
Farnsworth spacing sends each letter at full speed but stretches the gaps. Learners hear the real rhythm of every letter, for example at 18 WPM, while getting more thinking time between letters, as if the overall speed were 10 WPM.
Reading and writing Morse here
The most common letters have the shortest codes: E is a single dot, T a single dash, A is .- and N is -. . In the output, letters are separated by spaces and words by a slash. When decoding, dots can be typed as . or · and dashes as -, – or _, and / or several spaces mark a new word. Because the same code means different letters in Latin, Cyrillic, Wabun and Korean Morse, pick the alphabet before decoding.
Frequently asked questions
How do I translate Morse code to English?
Type or paste dots and dashes into the box, with spaces between letters and a slash between words. The tool detects Morse automatically and shows the text.
What is SOS in Morse code?
SOS is ... --- ... (three dots, three dashes, three dots). It is sent as one continuous signal without the usual gaps between letters.
What speed should I start with?
Many learners start with letters at 18 to 20 WPM and Farnsworth spacing at about 5 to 10 WPM, then shorten the gaps as recognition improves.
Do I need Morse code for an amateur radio license?
In most countries no longer. The international requirement was removed in 2003, and the United States dropped its Morse test in 2007, but many operators still use CW.
Can I download the sound?
Yes. WAV saves the audio with your chosen speed, tone and spacing, including the optional radio static and fading.
