What is Morse code?
Morse code is a method of encoding text information using a series of dots and dashes (or short and long signals). Invented by Samuel Morse in the 1830s for the telegraph, it remains widely used in aviation, amateur radio, and emergency signaling today.
How does Morse code conversion work?
Each letter and number is mapped to a unique pattern of dots (short signals) and dashes (long signals). For example, 'S' is three dots (...), 'O' is three dashes (---), and the famous SOS signal is ...---...
Can I convert Morse code back to text?
Yes, this tool supports bidirectional conversion. You can decode Morse code back to readable text instantly.
Can I use custom symbols for dots and dashes?
Yes, you can customize the dot and dash characters to any symbols you prefer, such as * and -, or ● and —.
Is my data safe and private?
Absolutely. All processing happens locally in your browser. No data is sent to any server, ensuring complete privacy and security.
Does this tool work offline?
Yes, once the page is loaded, it works 100% offline. No internet connection is required for conversion.
What is the difference between International Morse Code and other variants?
International Morse Code is the standard used worldwide today. There are also historical variants like the original American Morse Code (used in early telegraphy) and Japanese Wabun Code, but International Morse is the most common.
How fast can Morse code be transmitted?
Speed is measured in words per minute (WPM). Beginners typically start at 5-10 WPM, while experienced operators can achieve 20-30 WPM or more. The world record exceeds 75 WPM.
Is Morse code still used today?
Yes, Morse code is still used in aviation navigation (NDBs), amateur radio communications, assistive technology for people with disabilities, and as an emergency signaling method (SOS).
What are the basic rules of Morse code timing?
A dash is three times the length of a dot. The space between parts of the same letter is one dot length. The space between letters is three dot lengths, and the space between words is seven dot lengths.
Can I learn Morse code with this tool?
Yes, this tool is excellent for learning. You can practice converting text to Morse and back, and use the audio playback feature to train your ear.
What is the most common Morse code signal?
SOS (...---...) is the most internationally recognized Morse code signal, used as a distress signal. It was chosen because it's easy to remember and transmit.
