Morse Code Converter
A tool that converts between characters and Morse code, and can play the code as sound
Features
Automatically distinguishes between characters and code
Converts code-only input to characters, otherwise converts to code
Switch between Western and Japanese formats
Supports both alphabets, numbers, symbols and Japanese kana
Playback with dot and dash sounds
Speed adjustment from 5 to 40 WPM and highlighting of the playing character
Quickly check the code reference table
Open and compare Western and Japanese code tables on the spot
How to Use
Select the code type and notation
Choose between Western or Japanese format, and whether to write the code as ". and -" or "· and −"
Enter a character or Morse code
Paste a character or code in the input field. For code, separate characters with spaces and words with /
Check the result and play the sound
Confirm the result that appears as you type, and use "Play sound" to adjust the playback speed while listening
Copy and use the result
Use the "Copy" button to take the result and paste it into social media or messages
Use Cases
Decoding code seen on social media
Paste Morse code you see in movies, anime, games, or social media to check what it says
Create messages in code
Convert words like "thank you" into code and add a playful touch to social media posts or message cards
Creating puzzle and escape game problems
Use conversion results and code reference tables to create and verify cipher problems
Practice listening to radio and disaster prevention broadcasts
Start with slow speed and gradually increase, listening to the same code multiple times to practice distinguishing between dots and dashes
Basic Knowledge
What is Morse code
Morse code is a communication method that represents characters using combinations of short sounds (dots) and long sounds (dashes). For example, the letter A in the alphabet is represented as "·−" and E as "·".
- Western Morse code：Western Morse code is an internationally standardized code representing 26 letters of the alphabet, numbers, and symbols, as defined by the international standard ITU-R M.1677-1.
- Japanese Morse code：Japanese Morse code is a uniquely Japanese code representing 48 kana sounds of the Iroha and voiced sounds, semi-voiced sounds, and long vowels. Although using the same "·−", it represents the letter A in Western code but the sound "i" in Japanese code.
Why SOS becomes "···−−−···"
SOS was chosen as an international distress signal because of its easy-to-remember and hard-to-mistake pattern of 3 dots, 3 dashes, and 3 dots, and is not an abbreviation for "Save Our Ship" or similar. In actual distress signals, characters are sent continuously without gaps as a single code.
Rules for separating characters and words
The length of Morse code is determined using one dot as a unit, and the length ratio remains the same regardless of the speed of transmission.
- Code length：A dash is three times the length of a dot, and within a single character, there is a silent gap of one dot length between dots and dashes.
- Between characters and words：There is a silent gap of 3 dot lengths between characters and 7 dot lengths between words. When writing in characters, it is common to separate characters with spaces and words with "/".
- Speed unit WPM：WPM refers to the number of words transmitted per minute. Using "PARIS" as the standard for one word, the length of one dot is 1200÷WPM milliseconds, which is 80 milliseconds at 15 WPM.
