About Morse Code Converter Online
This tool converts between text and Morse code in both directions. Type text and get its Morse code sequence of dots (·) and dashes (−); paste Morse code and get the decoded text.
Morse code was developed in the 1830s for telegraph communication. Each letter, digit, and punctuation mark has a unique pattern. Despite being nearly 200 years old, it remains useful for amateur radio, emergency communications (the famous SOS = · · · − − − · · ·), accessibility, and learning the foundational concepts of digital communication.
The tool supports international Morse code including punctuation, and lets you play the result as audio at adjustable speed — useful for practising Morse code reception.
How to use this tool
How to translate between text and Morse code
Enter the input
Drop your text or Morse into the "Input" field. The tool encodes letters A–Z and digits 0–9; uppercase/lowercase are treated identically.
Pick a direction
"Direction" toggles `encode` (text → Morse) and `decode` (Morse → text). Morse tokens are separated by single spaces; whole words by ` / ` (space-slash-space) in this format.
Press Run
Result is a single `output` field — the converted string. Unknown characters in encode mode become empty strings (silently dropped); unknown tokens in decode mode also drop silently.
Where Morse still matters
Modern uses: ham radio (where CW is still common), accessibility (single-switch input), and aviation NAVAID identifiers. The Morse here is International, not the older American Morse used pre-1900.
