About Morse Code Encoder / Decoder
Our free online Morse Code Encoder/Decoder is a powerful tool that converts text to International Morse code and decodes Morse code back to readable text. Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks.
Developed in the 1830s by Samuel Morse and Alfred Vail, Morse code was the primary method for long-distance communication via telegraph wires. Each character is represented by a unique sequence of dots (short signals) and dashes (long signals), separated by spaces.

Frequently Asked Questions
What is Morse code?
Morse code is a method of encoding text characters as sequences of two different signal durations, called dots (dit) and dashes (dah). It was developed by Samuel Morse and Alfred Vail in the 1830s for use with the telegraph.
What is the SOS signal in Morse code?
SOS in Morse code is "... --- ..." (three dots, three dashes, three dots). It is the international distress signal and is one of the most well-known Morse code sequences. It does not stand for any particular words.
Is Morse code still used today?
While Morse code is no longer used for commercial telecommunications, it is still used by amateur radio operators, in aviation navigation (NDB and VOR beacons), and as an assistive communication method for people with disabilities.
How fast is Morse code played?
Morse code speed is measured in words per minute (WPM). This tool offers three speed settings: Slow (about 5 WPM), Medium (about 10 WPM), and Fast (about 20 WPM), suitable for beginners to experienced operators.
Is this Morse code tool free?
Yes, it is completely free to use with no registration, sign-up, or limits. You can use it as many times as you need for personal, educational, or commercial projects.
Can I use this tool offline?
Yes, once the page is loaded, all Morse code conversion and audio playback happens entirely in your browser using JavaScript and the Web Audio API. No server communication is needed after the initial page load.
