Morse Code Translator

Turn text into Morse, or decode written signals

This translator works in both directions: enter a message to see dot-and-dash notation, or enter separated Morse groups to read the text. International Morse represents characters with short and long signals. In writing, those are commonly shown as dots and dashes; the ITU publishes the International Morse code recommendation. This page also lets you choose replacement symbols and separators when both sender and reader use the same settings.

Morse is an encoding convention. It changes how characters are represented; it does not encrypt or protect a message. The Play control makes tones from text entered in encoding mode. It does not listen to a recording, upload audio, or transcribe beeps into text.

Convert a message and check the spacing

1. Choose a direction

   Start with text-to-Morse, or use Swap to change to Morse-to-text. Swap carries the current result into the input so you can check a conversion in reverse.

2. Enter text or separated code

   For example, enter SOS to encode it as ... --- .... For decoding, separate letters with the character separator and words with the word separator. With defaults, a slash marks a word break.

3. Read or play the output

   The result updates as you type. In encoding mode, Play creates an audible tone from the standard dot-and-dash representation. Copy the displayed result when you need to paste it elsewhere.

Custom symbols

Short code, long code, character separator, and word separator can each be changed. Keep the short and long symbols distinct, and make sure separators do not create ambiguous tokens. The recipient must use the same choices to decode reliably. Reset restores dot, dash, a space between characters, and slash between words.
