Quick answer

Morse is a free, private online tool that lets you translate text to Morse code or decode Morse back to text. It runs entirely in your browser, so nothing you enter is uploaded to a server.

How to use the Morse

  1. Choose the mode you need with the Encode / Decode toggle at the top of the tool.
  2. Type or paste your text into the Input box — the result appears instantly as you type.
  3. Use Swap (⇅) to move the output back into the input and flip the mode, which is handy for round-trips.
  4. Click Copy to copy the result, or Clear to start over.

Privacy: this tool runs entirely in your browser. Your input is never sent to, received by, or stored on any server — there are no uploads and no tracking of what you enter.

About Morse

What is Morse code?

Morse code encodes characters as sequences of dots (.) and dashes (-). Developed for the telegraph in the 1800s, it's still used in aviation, amateur radio and emergencies because it can be sent by sound, light or tapping.

How to format it

In this tool, letters within a word are separated by a single space and words are separated by /. For example .... .. is "HI" and ... --- ... is the famous SOS.

Supported characters

All 26 letters, digits 0–9, and common punctuation (period, comma, question mark, slash and more) are supported in both directions.

Frequently asked questions

How are words separated?
With a forward slash /. Letters inside a word are separated by single spaces.
Is Morse case-sensitive?
No. Morse code has no concept of upper- or lower-case; text is treated case-insensitively when encoding.
What is SOS in Morse?
... --- ... — three dots, three dashes, three dots. It's an internationally recognised distress signal.

Understanding Morse in depth

What Morse code is

Morse code represents letters, digits and punctuation as sequences of dots and dashes (short and long signals). Developed in the 1830s and 40s for the electric telegraph, it allowed text to be sent over a single wire - or later by radio, light or sound - and it remains in use in aviation, amateur radio and emergency signalling.

How the translation works

Each character maps to a unique pattern: E is a single dot, T a single dash, S is three dots, O is three dashes - which is why SOS (... --- ...) is so simple and recognisable. This tool converts text to Morse and back. In the output, letters within a word are separated by spaces and words are separated by a slash (/).

Why dots and dashes

The cleverness of Morse is that common letters get short codes and rare letters get longer ones, making messages efficient to send by hand - an early form of data compression. Because it reduces communication to a simple on/off signal, it can be transmitted by almost any medium: a telegraph key, a flashing light, a tapped sound, or a radio tone.

Where it is still used

Morse endures because it is robust and minimal. Aviation navigation beacons identify themselves in Morse; amateur radio operators use it to make contacts in poor conditions where voice fails; and SOS remains an internationally recognised distress signal. It can even be tapped or blinked by someone unable to speak, making it a genuine survival skill.

How to use it

Type text to convert it to Morse, or paste Morse (using spaces between letters and / between words) to translate it back. It supports letters, digits and common punctuation. Everything runs in your browser.
