What is Morse code?

Morse code is an encoding system that represents every letter, number and sign with combinations of short signals (dots) and long signals (dashes). It was developed in the 1830s by Samuel Morse and Alfred Vail for the electric telegraph, and for over a century it was the universal language of long-distance communication: telegraph lines, maritime radio and aviation.

A Morse code translator automates that conversion in both directions: type "hello" and you get .... . .-.. .-.. ---, or paste a sequence of dots and dashes and recover the original message. This tool does it instantly as you type, without uploading anything to a server.

Although digital communications have long replaced it, Morse is still alive among amateur radio operators, in scouting, escape rooms and as a teaching resource. And its most famous signal, SOS ( ... --- ... ), remains the international symbol of distress.

How to translate text to Morse step by step

1

Choose the translation direction: "Text → Morse" to encode your message or "Morse → Text" to decipher a sequence of dots and dashes.

2

Type or paste your message into the box. The translation appears instantly; if any character has no equivalent, the tool tells you below the result.

3

Press "Copy" to grab the result or "Play" to hear the Morse at the speed you prefer.

The full Morse alphabet

This is the complete international Morse alphabet the translator uses: all 26 letters, the 10 digits and the most common punctuation marks. Click any cell to copy its code.

Accented letters deserve a note: the basic international alphabet covers A–Z only, but the extension for other languages assigns codes to several special characters — the Spanish ñ is --.--, á is .--.- and é is ..-... This translator recognises them automatically; accents without a code of their own fold back to the base letter, exactly as real telegraph operators did.

Listen to the Morse: dots and dashes

Morse is not just read — it is heard. The whole system is built on one unit of time, the dot (dit). A dash lasts 3 dots, the silence between signals inside a letter lasts 1 dot, the silence between letters lasts 3 dots and the silence between words lasts 7. From that rhythm comes the WPM (words per minute) speed measure, calculated with the standard word "PARIS".

The "Play" button on this tool reproduces your message with a 600 Hz tone, the classic timbre of radiotelegraphy. Start at slow speed (12 WPM) if you are learning: experienced operators decode more than 25 WPM by ear, recognising each letter by its "melody" instead of counting dots and dashes.

Morse and binary: two ways to encode

Morse was, in a way, the precursor of digital encoding: it reduces all language to two symbols, just as binary reduces everything to zeros and ones. The difference is that Morse gives shorter codes to the most frequent letters (E is a single dot), while modern binary uses fixed lengths per byte.

If this family of encodings interests you, also try our text to binary translator: it converts any message to UTF-8 binary code and back, with full support for accents and emojis.

Frequently asked questions

Is this Morse code translator free?
Yes, it is completely free with no sign-up. Translation happens entirely in your browser — nothing is sent to any server, so you can translate as many messages as you like.
How do accented letters work in Morse code?
The international extension assigns codes to some accented letters: ñ is --.--, á is .--.- and é is ..-.. — this translator recognises them automatically. Accents without their own code fall back to the base letter, just like real telegraphy did.
Does Morse code have uppercase and lowercase?
No. Morse code has no letter case: "SOS" and "sos" translate exactly the same. That is why decoded text is always shown in lowercase.
How are letters and words separated in Morse?
Each letter is separated with a space and each word with a forward slash ( / ). When decoding, this tool also accepts three or more spaces as a word separator.
Can I listen to the Morse code?
Yes. Press the "Play" button and the tool reproduces the dots and dashes with a 600 Hz tone, just like real radiotelegraphy. Choose between slow (12 WPM), normal (18 WPM) and fast (25 WPM).
What does SOS mean in Morse?
SOS ( ... --- ... ) is the international distress signal adopted in 1906. It does not stand for any phrase: it was chosen because its pattern of three dots, three dashes and three dots is unmistakable even through heavy interference.
