How to Use Morse Code Translator
The Morse Code Translator makes it effortless to convert between plain text and Morse code without memorizing any charts.
- Select a mode — Choose "Text → Morse" to encode your message, or "Morse → Text" to decode.
- Enter your input — Type any English text, digits, or punctuation into the input box. For Morse input, use dots (
.) and dashes (-), separating letters with spaces and words with/. - Read the result — The Morse Code Translator converts your input instantly as you type.
- Copy the output — Click the Copy button to copy the result to your clipboard.
If the Morse Code Translator encounters a character it cannot map, it will flag it with a friendly warning rather than silently ignoring it.
Formula & Theory — Morse Code Translator
The Morse Code Translator is based on International Morse Code, standardised by the ITU. Each letter and digit is assigned a unique sequence of dots and dashes:
A = .- B = -... C = -.-. D = -..
E = . F = ..-. G = --. H = ....
I = .. J = .--- K = -.- L = .-..
M = -- N = -. O = --- P = .--.
Q = --.- R = .-. S = ... T = -
U = ..- V = ...- W = .-- X = -..-
Y = -.-- Z = --..
0 = ----- 1 = .---- 2 = ..--- 3 = ...--
4 = ....- 5 = ..... 6 = -.... 7 = --...
8 = ---.. 9 = ----.
| Symbol | Meaning |
|---|---|
. |
Dot (short signal) |
- |
Dash (long signal) |
|
Separator between letters |
/ |
Separator between words |
The Morse Code Translator applies these rules bidirectionally — text to Morse and Morse to text — with full UTF-8 input support.
Timing Conventions
In traditional radio telegraphy a dot lasts one unit, a dash three units, the gap between symbols within a letter is one unit, the gap between letters is three units, and the gap between words is seven units. The Morse Code Translator represents these gaps as spaces and slashes in text form.
Use Cases for Morse Code Translator
The Morse Code Translator is useful across a wide range of applications:
- Amateur radio (ham radio) — Encode outgoing messages or decode received CW (continuous wave) signals using the Morse Code Translator before transmitting.
- Education — Students learning Morse code can practice encoding and decoding with instant feedback from the Morse Code Translator.
- Escape rooms and puzzles — Game designers and players use the Morse Code Translator to create or crack Morse-based ciphers and clues.
- Emergency signaling — The universal SOS signal (
... --- ...) and other distress codes can be verified with the Morse Code Translator. - Historical research — Researchers studying telegraphic communications can decode historical Morse transcripts using the Morse Code Translator.
