Type or paste text and press Run. Each character is lower-cased and looked up in an International Morse table. Letters become their dot-and-dash pattern; the patterns are joined with a single space. Anything that is not a letter A to Z — the space between words, digits, punctuation — is replaced with a slash. A word gap therefore shows up as / with a space on each side.
Input SOS produces:
... --- ...Input HI THERE produces:
.... .. / - .... . .-. .The / marks where the space between "HI" and "THERE" was.
Standard International Morse uses timing units: a dot is 1 unit, a dash is 3 units, the gap between parts of the same letter is 1 unit, the gap between letters is 3 units, and the gap between words is 7 units. When Morse is written rather than keyed, the convention this tool follows is a single space between letters and a slash between words.

The digit column is for reference; this tool encodes letters only and renders digits as a slash.
Encoding short messages for amateur radio practice, building a puzzle or escape-room clue, adding a Morse Easter egg to a game or website, teaching the alphabet, or checking a call sign's pattern before you key it.
No. Input is lower-cased before lookup, so SOS and sos give the same result.
Not on this page — it is text-to-Morse only.
As a slash. Every non-letter, including the space between words, becomes /.
