Morse Code Translator

This translator turns text into Morse code and Morse code back into text, and it can play the code as sound. Type in either panel and the other updates at once. "SOS" becomes ... --- ..., with a space between letters and a slash between words.

Morse code spells each character with short signals, called dots or dits, and long signals, called dashes or dahs. The tool covers the 26 letters, the digits 0 to 9 and 18 punctuation marks, from the period to the @ sign. Accents are removed before encoding, so é is sent as E. Anything with no Morse code, such as an emoji, is skipped. When you decode, any code the tool does not know shows as #.

Press Play Morse to hear the message as a 600 Hz tone. The speed runs from 5 to 30 words per minute, with 15 as the default. The timing follows the standard ratios. A dash lasts as long as three dots. The gap inside a letter is one dot, the gap between letters is three dots and the gap between words is seven. At 20 words per minute, one dot lasts 60 milliseconds.

To learn by ear, start slow and raise the speed as the rhythm of each letter sinks in. The reference chart below the player lists every supported character. To spell words aloud instead, use the NATO Phonetic Alphabet converter. For 1s and 0s rather than dots and dashes, try Text to Binary.
