Morse Code Generator — Convert Text to Morse Code

The generator is the text-to-Morse half of the translator. It runs in the same two-panel tool, so you do not have to switch modes or press a convert button.

1. Type or paste your text. Letters, numbers and common punctuation are supported. The result appears in the right panel as you type.
2. Check the spacing. The generator puts one space between character codes and a slash between words. A word gap is longer than a letter gap in the audio, so the receiver can hear where one word ends and the next begins.
3. Listen, copy or download. Press Play to hear the rhythm, Copy Morse to put the code on the clipboard, or WAV to save the audio as a 44.1 kHz, 16-bit mono file.

If you would rather start from a code and turn it into text, use theMorse code decoder. It follows the same spacing rules in reverse.

The Latin set covers A–Z, 0–9 and the punctuation that International Morse code defines, including the period, comma, question mark, slash, parentheses, ampersand, colon, semicolon, equals sign, plus sign, hyphen, underscore, quotation mark, dollar sign and at sign. Latin Extended adds accented letters such as É, Ł and Ó.

The character set selector also exposes Cyrillic, Greek, Hebrew, Arabic, Persian, Japanese (Wabun), Korean and Thai. Encoding searches all of these sets, so you can generate a Cyrillic or Greek message without changing a setting. The selector matters most when you decode, where more than one letter can share the same code.

A character that has no code in any set becomes a # in the output. Emoji, currency signs such as € and symbols outside the tables are the usual causes. Replace them with a supported spelling, or set the API's invalid option to an empty string if you are building your own encoder.

Written Morse needs a separator because the code itself has no fixed length. The usual convention is one space between letters and a slash between words: SOS becomes ... --- ..., andHELLO WORLD becomes .... . .-.. .-.. --- / .-- --- .-. .-.. -...

In the audio, the same boundaries are three units between letters and seven units between words. A dot is one unit and a dash is three. At 20 WPM one unit is 60 milliseconds, so the silence is short but audible. If you paste the output into another tool, keep the spaces and the slash; removing them changes the message.

The generator also accepts three-space word gaps, newlines and the middle-dot/long-dash forms common in printed charts. It normalises them to the standard ., - and / output.

Words per minute, or WPM, controls how fast the code is sent. The slider runs from 5 to 40 WPM and uses the PARIS standard: one unit is 1.2 / WPM seconds. At 20 WPM a dot lasts 60 ms and SOS takes 1.62 seconds. At 12 WPM the same SOS takes 2.7 seconds; at 30 WPM it takes 1.08 seconds.

The tone slider sets the audio frequency from 400 to 1000 Hz, with 600 Hz as the default. The volume slider is independent. The WAV button renders the current message with the same speed, tone and volume, so the file you download sounds like the preview you just heard.

The generator is designed for short messages, callsigns, puzzle clues and practice words. For a long text, the browser still renders the audio locally, but the WAV file can take a moment to build.

Try one of the example chips under the tool to load a message, then change the speed and listen for the difference between the three-unit letter gaps and the seven-unit word gaps.
