Morse code is a telecommunication encoding system that represents letters and numerals as sequences of dots and dashes (or short and long signals). It was developed by Samuel Morse and Alfred Vail in the 1830s.

About Morse Code

What Is Morse Code?

Morse code is a method of encoding text characters as standardized sequences of two different signal durations — called dots (·) and dashes (—). Developed in the 1830s by Samuel Morse and Alfred Vail for the electric telegraph, it became the first practical form of long-distance communication. A dot represents a short signal and a dash represents a long signal (three times the duration of a dot).

Today, Morse code is used by amateur radio operators, aviation, maritime navigation, and in emergency communication systems. It is also used as an assistive communication tool for people with certain disabilities.

How to Convert Text to Morse Code

Select Text to Morse mode using the toggle above the input box.
Type or paste your text into the input area. Letters (A–Z) and numbers (0–9) are fully supported.
Click Convert or press Enter.
The Morse code appears in the output box. Use the copy or download buttons to save your result.

Each letter is separated by a single space. Words are separated by three spaces in the output.

How to Decode Morse Code to Text

Select Morse to Text mode using the toggle.
Enter your Morse code using dots (.) and dashes (-).
Separate each letter with a single space.
Separate each word with three spaces.

Example: .... . .-.. .-.. --- decodes to HELLO.

History of Morse Code

Samuel Morse and Alfred Vail developed the original Morse code in the 1830s. The first public demonstration occurred on May 24, 1844, when Morse transmitted "What hath God wrought?" from Washington D.C. to Baltimore.

The International Morse Code — standardized in 1865 — replaced the original American Morse Code and added characters for non-English letters. The ITU (International Telecommunication Union) maintains the current standard. Despite advances in digital communication, Morse code remains legally recognized and is still used in aviation, amateur radio, and emergencies worldwide.

Common Morse Code Examples

Common words and their Morse code equivalents
Word	Morse Code
SOS	`... --- ...`
HELLO	`.... . .-.. .-.. ---`
WORLD	`.-- --- .-. .-.. -..`
YES	`-.-- . ...`
NO	`-. ---`
LOVE	`.-.. --- ...- .`
OK	`--- -.-`

Morse Code Timing Rules

International Morse code follows strict timing conventions based on a single unit (the duration of one dot):

A dot = 1 unit
A dash = 3 units
Gap between symbols in a letter = 1 unit
Gap between letters = 3 units
Gap between words = 7 units

Standard operating speed is measured in WPM (words per minute), with beginners starting at 5–10 WPM and experts reaching 20–30+ WPM.
