Morse Code Encoder/Decoder
ASCII letters, numbers, and punctuation use standard Morse. Chinese, Japanese, Korean, and other Unicode characters are wrapped in reversible Unicode Morse blocks so decoding restores the original text.
Separate letters with spaces and words with /. A-Z, 0-9, and common punctuation use standard Morse. Chinese, Japanese, Korean, and other Unicode characters are encoded as reversible blocks in the form of ........ + Unicode hex digits + --------.
Example: SOS becomes ... --- ..., and the character 你 becomes ........ ....- . ----. ..--- -.. --------, which decodes back to the original character.
- Enter text in the "Plain Text" field (supports English, Chinese, Japanese, and Korean).
- Click "Encode" to convert text into Morse code.
- Or paste Morse code into the "Morse Code" field and click "Decode" to restore text.
- Click "Swap" to quickly exchange both fields.
Tip:Standard letters are separated by spaces, words by /. CJK characters are stored in reversible Unicode blocks and are fully restored when decoded.
When is this useful?
- Learning Morse code dot-dash rules and memory techniques
- Decoding historical telegrams or vintage ciphers
- Practicing for amateur radio (HAM) exams
- Creating fun encrypted messages or puzzles
Who invented Morse code?
Morse code was developed by Samuel Morse and Alfred Vail in the 19th century and was widely used for telegraph communications.
What is the Morse code for SOS?
SOS in Morse code is ···−−−··· (three dots, three dashes, three dots) — the international distress signal.
Is Morse code still used today?
Commercial telegraphy is gone, but Morse code is still used in amateur radio (HAM), and some maritime and military contexts.
Does this tool support non-Latin characters?
Yes, Chinese, Japanese, and Korean characters are encoded as reversible Unicode Morse blocks and can be fully restored when decoded.
