Morse Code Converter
Encode text to Morse code or decode Morse back to text. Free, instant, and works with the international Morse code standard.
Our Morse code converter lets you encode plain text into Morse code (dots and dashes) and decode Morse code back into readable text. The tool follows the International Morse Code standard established by the International Telecommunication Union, covering all 26 Latin letters, digits 0 through 9, and common punctuation marks.
Morse code is one of the earliest forms of digital communication, developed in the 1830s by Samuel Morse and Alfred Vail for use with the electric telegraph. Each letter and number is represented by a unique sequence of short signals (dots) and long signals (dashes). For example, the famous SOS distress signal is encoded as three dots, three dashes, three dots. Despite being nearly 200 years old, Morse code remains relevant today in amateur radio, aviation, naval communication, accessibility technology, and emergency signaling.
The encode mode converts your plain text into standard Morse code notation using dots (.) and dashes (-). Letters are separated by spaces, and words are separated by a forward slash (/) or wider spacing. The decode mode reverses the process, taking Morse code input and converting it back to readable English text. This bidirectional capability makes the tool useful both for creating Morse code messages and for reading received Morse transmissions.
Students and hobbyists use the converter to learn and practice Morse code without needing physical equipment. Ham radio enthusiasts reference it when preparing for licensing exams or brushing up on less common characters. Escape room designers and puzzle creators encode clues in Morse code for their games. Geocachers encounter Morse-encoded coordinates and hints that need decoding. History enthusiasts explore the communication methods that connected continents before voice radio and the internet.
The converter also serves educational purposes in computer science and information theory, demonstrating how variable-length encoding works. Morse code is an elegant example of prefix-free coding that predates modern compression algorithms by over a century.

Morse Code FAQ
Morse code is a method of encoding text using sequences of dots (short signals) and dashes (long signals). Each letter and number has a unique pattern. It was invented in the 1830s for telegraph communication and is still used today.
Use a dot (.) for short signals and a dash (-) for long signals. Separate letters with a space and words with a forward slash (/). For example, 'SOS' is '... --- ...' and 'HI' is '.... ..'.
SOS in Morse code is ... --- ... (three dots, three dashes, three dots). It is the international distress signal chosen because the pattern is easy to recognize and transmit.
Yes. The converter supports all 26 Latin letters (A-Z), digits 0-9, and common punctuation marks including periods, commas, question marks, exclamation marks, and more.
Yes. Morse code is used in amateur (ham) radio, aviation navigation aids, naval communication, accessibility devices, and emergency signaling. It is required knowledge for some amateur radio licenses.
This tool works with written Morse code (dots and dashes as text characters). For audio Morse, you would first need to transcribe the sounds to dots and dashes, then paste that transcription into the decoder.

The converter uses the International Morse Code standard as defined by the International Telecommunication Union (ITU). This is the most widely used version globally.
