Morse Code Converter

Translate text to Morse code and back

This Morse code converter turns plain text into dots and dashes, and decodes Morse code back into letters and numbers. The result updates as you type. It is useful for learning the Morse alphabet, making puzzles and games, checking a message from a class or hobby project, or just having fun with codes.

How to use it

1. Pick a mode: Text → Morse or Morse → Text. Switching modes clears the input box.
2. Type or paste your text or Morse code into the input box.
3. Read the result in the Morse Code or Decoded Text panel and click Copy to copy it.
4. Click Show Morse Code Reference to open a chart of every letter and digit.

How it works

The tool uses the international Morse code table for the letters A to Z and the digits 0 to 9. Text is changed to upper case first, so "sos" and "SOS" give the same result. In the output, letters are separated by a single space and words by a slash with spaces around it.

For example, HELLO WORLD becomes:

.... . .-.. .-.. --- / .-- --- .-. .-.. -..

When decoding, the tool splits words on / and letters on single spaces, then looks up each code. Any code it does not know is shown as ?. Conversion runs in your browser, and nothing is saved.

Tips

• Punctuation, accented letters and other symbols are skipped when encoding. Only A–Z and 0–9 are converted.
• When decoding, use exactly one space between letters. Double spaces or a slash without spaces can produce ? in the result.
• Put each sentence on one line with spaces between words. A line break is not treated as a word gap.

Frequently asked questions

How do I write a space between words in Morse code?

Type a slash with a space on each side: / . The tool uses this both when it creates Morse code and when it decodes it.

Why do I see a question mark in the decoded text?

A ? means that group of dots and dashes is not a letter or digit in the table, or the spacing is off. Check for extra spaces or typos.

Does it support punctuation like commas or question marks?

No. Only the 26 letters and 10 digits are supported. Other characters are left out of the Morse output.
