Morse Code Translator

The Morse code translator is a free tool that runs entirely in your browser, with no data ever sent to a server. Translate text into Morse, or the other way around.

How Morse works

Each letter is coded as a run of short signals, the dots, and long ones, the dashes. The most frequent letters in English carry the shortest codes: E is a single dot, T a single dash. That is what made telegraph transmission fast.

Accents and punctuation

International Morse does not code accented letters. Characters such as é, è or à are therefore converted to their unaccented equivalent. Common punctuation, on the other hand, does have dedicated codes.

What this tool does not do

This tool handles written Morse, as dots and dashes. It neither produces nor recognises sound, and does not treat radio abbreviations such as SOS as a single block.

Frequently asked questions

How do you write SOS in Morse?

Three dots, three dashes, three dots: ... --- ... It is the international distress signal, chosen for its simplicity and instant recognition, not for its initials.

Is capitalisation preserved?

No: Morse makes no difference between upper and lower case. Decoded text therefore comes out in capitals.

Is my data sent to a server?

No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need an account or an install?

No: the tool works directly on this page, with no sign-up and no installation.
