Text to Morse Code Converter

A text to Morse code converter is an encoder that replaces every character with its fixed International Morse Code pattern. The letter E becomes ·, the letter T becomes −, and the word SOS becomes ··· −−− ···.

The converter follows Recommendation ITU-R M.1677-1, which defines 26 letters, 10 numbers and 18 punctuation marks. The most common English letters get the shortest codes, so ordinary text encodes compactly.

Text becomes Morse code in 5 steps: split, normalise, look up, separate and time. The converter splits your message into words and characters, converts lowercase to uppercase, finds each character in the Morse table, joins the codes with letter and word separators, and calculates the timing.

Characters without a Morse code, such as emoji or the # sign, are skipped and listed in a warning under the output, so the rest of the message still converts.

Our converter writes Morse code in 4 output formats: dot-dash, typographic, spoken and binary. Dot-dash text (. and -) pastes anywhere, typographic symbols (· and −) read best on screen, spoken syllables help you memorise rhythm, and binary timing (1 and 0) feeds electronics projects.

You also choose the separators. A space between letters and a slash (/) between words is the most common style, and our Morse code to text decoder reads all of these formats back.

A Morse message takes its total timing units multiplied by 1.2 ÷ WPM seconds. The word PARIS is 50 units long, so at 20 WPM one unit lasts 60 milliseconds and PARIS takes 3 seconds.

Letters with many dashes take longer: E lasts 1 unit, while 0 (−−−−−) lasts 19 units. The converter adds up every dot, dash and gap to show the exact send time for your message.
