Morse Code Encoder/Decoder: Convert Your Messages Instantly
Transform any text into Morse code or decode Morse messages into readable text with our free online tool. Whether you're a ham radio operator, history enthusiast, or just curious, this Morse encoder lets you communicate like in the telegraph era.
Morse code is an encoding system that represents each letter and number with a unique combination of dots (•) and dashes (−). Invented by Samuel Morse in 1837, it's still used today in aviation, maritime navigation, and by amateur radio operators worldwide.

❓ Frequently Asked Questions (FAQ)
Which Morse standard is used?
We use the International Morse Code (ITU-R M.1677-1), the universal standard used by amateur radio operators, maritime services, and aviation. This standard is recognized worldwide and ensures maximum compatibility.
How are letters and words separated?
In Morse code:
- Between letters: a single space
- Between words: a slash (/) or three spaces
Example: "HELLO WORLD" → .... . .-.. .-.. --- / .-- --- .-. .-.. -..
Are special characters supported?
Supported characters include:
- Letters A-Z (lowercase is converted to uppercase)
- Digits 0-9
- Common punctuation: . , ? / @ ! ( ) & : ; = + - _ " ' $
Unrecognized characters (accents, emojis, etc.) are simply ignored.
Is my data secure?
Yes, 100%! All processing happens locally in your browser using JavaScript. Your text and Morse code never leave your device and are never transmitted to our servers. The tool works offline once the page is loaded.
What is the SOS signal in Morse?
SOS is the most famous international distress signal. In Morse code, it's written: ... --- ... (three dots, three dashes, three dots).
Contrary to popular belief, SOS doesn't stand for "Save Our Souls" or "Save Our Ship". These letters were chosen for their simple, recognizable pattern that's easy to remember and transmit in emergencies.
