Morse Code Translator & Decoder

Convert text into standard International Morse Code and vice versa. Invented by Samuel Morse around 1836, this system encodes text characters as standardized sequences of two different signal durations, called dots (short) and dashes (long). It was critical for early telecommunication via telegraph and radio, and remains relevant today in aviation, amateur radio (HAM), and emergency signaling (SOS).

Morse Code

Encodes text using dots and dashes for telecommunication

Encoding Rules:

  • Dots (·) and dashes (−) represent letters
  • Spaces separate letters, slash separates words
  • Supports A-Z and 0-9
  • Example: "SOS" → "... --- ...", "HELLO WORLD" → ".... . .-.. .-.. --- / .-- --- .-. .-.. -.."

Frequently Asked Questions FAQ
What is the SOS signal in Morse?
SOS is the most famous Morse signal: ... --- ... (Three dots, three dashes, three dots). It is a continuous distress signal, chosen for its simplicity and distinctiveness.
How are spaces handled?
In written Morse, letters within a word are separated by a space, and words are separated by a slash (/) or a wider space. Our tool uses standard conventions, but you can interpret slashes as word breaks.
Is Morse Code still used?
Yes! While no longer used for official maritime communication, it is extremely popular among amateur radio operators and is often used as an assistive technology for people with varying abilities to communicate.
