Morse Code Translator
Convert text to Morse code or decode Morse back to text — full International Morse alphabet, digits, and punctuation, with adjustable separators. Runs entirely in your browser, no server, no sign-up.
What this tool does
Translate plain text into International Morse code, or decode Morse code back into text — instantly and right in your browser. Nothing is sent to a server: it runs locally, works offline, and needs no sign-up. Pick a Direction, paste your input, and optionally tweak the separators.
Direction
| Direction | What it does |
|---|---|
| encode (default) | Turns text into Morse — SOS becomes ... --- .... |
| decode | Turns Morse back into text — ... --- ... becomes SOS. |
Encoding is case-insensitive (Hello and HELLO give the same Morse). Any
character that isn't in the Morse alphabet is replaced by the code for ?, so the
output is still decodable.
Separators
Morse code on its own is just dots and dashes — the spacing is what tells letters and words apart. You can set both:
- Letter separator — placed between the symbols for each letter. The default
is a single space (
.... ..=HI). - Word separator — placed between words. The default is
/(space-slash-space), the convention used in most printed Morse.
Leave a field blank to use its default. When decoding, the tool also accepts an
underscore (_) anywhere a dash (-) would appear.
Supported characters
- Letters: A–Z (case-insensitive).
- Digits: 0–9.
- Punctuation:
. , ? ' ! / ( ) & : ; = + - _ " $ @
Examples
| Input | Direction | Output |
|---|---|---|
SOS | encode | ... --- ... |
Hello World | encode | .... . .-.. .-.. --- / .-- --- .-. .-.. -.. |
... --- ... | decode | SOS |
.... .. / -.-- --- ..- | decode | HI YOU |
2026 | encode | ..--- ----- ..--- -.... |
FAQ
Is it free and private?
Yes — your input never leaves your device, and the translator keeps working offline once the page has loaded. There is no sign-up and nothing is logged.
Which Morse standard does it use?
The International Morse code (ITU-R M.1677-1) alphabet — the same letters,
digits, and punctuation used worldwide for amateur radio and signalling, plus a
few everyday extras like @ and $.
What happens to characters that have no Morse code?
When encoding, any character outside the supported set is replaced by the code
for ? (..--..) so the message still translates cleanly.
How do I decode Morse with unusual spacing?
Set the Letter separator and Word separator to
match the spacing in your input. For example, if words are split with a pipe
(|) and letters by a single space, set the word separator to
| and leave the letter separator blank.
Can I convert numbers and punctuation?
Yes — digits 0–9 and common punctuation (. , ? ! / : ; = + - " $ @
and more) all have Morse codes and round-trip both ways.
