Morse Code Translator
Translate plain text (A-Z, 0-9, punctuations, Hangul) to Morse code or decode Morse back to plain text.
※ Korean text is decomposed into consonant and vowel units; compound jamo such as ㅖ, ㅘ, and ㄳ are translated as basic jamo combinations. Korean decoding mode also decodes numbers (0-9).
※ Supported punctuations: period (.), comma (,), question mark (?), exclamation mark (!), at sign (@)
Usage Tips
Learn Morse code more easily with sound and light
Morse code can be hard to memorize by sight alone, but checking short and long signals with sound or light makes it easier to get used to the patterns. Korean text is converted by splitting consonants and vowels, so start with short words and check each jamo signal step by step.
What is Morse Code Translator?
The Morse Code Translator converts text to Morse and decodes Morse back to text. It supports A-Z, numbers, and common punctuation, and it handles Korean by decomposing Hangul into consonants and vowels without romanization.
How to Use
- 1Type text and run Text → Morse.
- 2Paste Morse code and run Morse → Text.
- 3Switch notation between . - / and · — /, then copy the output.
- 4Use Play to hear the signal and tune WPM, tone frequency, volume, and flash as needed.
Morse code depends on signal length and spacing
Last reviewed: July 11, 2026Morse timing formula
dot = 1 unit, dash = 3 units, letter gap = 3 units, word gap = 7 units; dot duration(ms) = 1200 ÷ WPM
Accurate audio or flash output needs both the dot-dash mapping and the timing gaps that separate letters and words.
Playing SOS at 20 WPM
- • Input SOS
- • Morse output ... --- ...
- • Speed 20 WPM
- 1. Dot duration = 1200 ÷ 20 = 60ms
- 2. Encode S as ... and O as --- with separation between letters
SOS appears as ... --- ..., and each dot uses a 60ms base duration at 20 WPM.
How to read the result
- ASCII style is easy to copy, while dot-dash symbols make relative signal length more visible.
- Korean text is decomposed into Hangul jamo rather than romanized before Korean Morse conversion.
Conditions that change the result
- Some punctuation or unsupported characters may not have a direct mapping in the selected language table.
- Flashing output can be uncomfortable for sensitive users, so check the environment before enabling it.
Common input mistakes
- Removing letter spaces or word separators makes it difficult for a decoder to recover boundaries.
- Increasing WPM speeds the whole playback, so verify that the result remains audible or visible to the audience.
Reference Knowledge
- ●Morse code represents letters and numbers with short and long signals.
- ●A dot is one unit long, while a dash is usually three units long.
- ●Spaces between signals, letters, and words help separate the message clearly.
- ●Korean Morse code decomposes Hangul syllables into consonants and vowels instead of romanizing pronunciation.
- ●SOS is one of the most recognized Morse code sequences: ... --- ...
FAQ
Q.How do I use the Morse code translator?
Enter text to convert letters, numbers, and common punctuation into Morse code. You can also paste Morse code to decode it back into text.
Q.Does it support Korean text?
Yes. Korean text is not romanized. Hangul syllables are decomposed into consonants and vowels, then converted using the Korean Morse code system.
Q.Why does Korean Morse output consonants and vowels?
Korean Morse code works at the jamo level, so Hangul syllables are decomposed before conversion.
Q.Can I play Morse code as sound?
Yes. The audio player can beep dots and dashes, with adjustable speed, tone frequency, and volume.
Q.Can I flash Morse code on screen?
Yes. The flash option lights up a signal lamp in sync with the Morse timing. Keep it turned off if you are sensitive to flashing lights.
Q.Can I copy the result?
Yes. You can copy the Morse code or decoded text and use it in messages, lessons, games, or escape room clues.
