What Is Morse Code?
Morse code is a character encoding system that represents letters, numbers, and punctuation as sequences of short and long signals called dots and dashes. Developed in the 1830s for use with the electric telegraph, it became one of the earliest forms of long-distance communication. This tool supports the International Morse Code standard, covering A-Z, 0-9, and common punctuation marks.
History of Morse Code
Morse code was developed by Samuel Morse and Alfred Vail in the 1830s alongside the invention of the electric telegraph. The original American Morse Code was later refined into the International Morse Code standard, adopted in 1865, which is still in use today. It played a vital role in maritime communication, wartime messaging, and early aviation. The famous SOS distress signal (... --- ...) was adopted in 1906 and remains universally recognized.
Use Cases
- Amateur (ham) radio communication worldwide.
- Emergency signaling — the SOS signal (... --- ...) is universally recognized.
- Aviation and maritime communication in certain contexts.
- Educational purposes: learning about communication history and encoding systems.
- Accessibility tools for people who communicate through simple binary inputs.
- Puzzle games, escape rooms, and geocaching challenges.
Notation Reference
In Morse code, a dot (.) represents a short signal and a dash (-) represents a long signal (three times the length of a dot). Within a letter, dots and dashes follow one another without separation. Letters within a word are separated by a space (equal to three dot lengths). Words are separated by a forward slash / (equal to seven dot lengths). For example, "SOS" is written as: ... --- ...

FAQ
What is the difference in length between a dot and a dash?
A dot is the base unit of length, and a dash is three times as long. The gap within a letter is one dot, between letters three dots, and between words seven dots. In this tool's text notation, a dot is written as "." and a dash as "-".
Is the message I type sent to a server?
No. All text-to-Morse and Morse-to-text conversion runs entirely in your browser, and nothing you type is ever sent to or stored on a server. You can convert private messages with confidence.
Which characters and symbols are supported?
Based on the International Morse Code standard, the tool supports A-Z, 0-9, and common punctuation marks. Characters not in the table and emoji cannot be converted, and uppercase and lowercase letters map to the same code.
How do I write separators when entering Morse code?
Write the dots and dashes of a single letter together, separate letters with a single space, and separate words with a forward slash (/). For example, "SOS" is `... --- ...`, and a word break looks like `.... .. / -`.
How do I enter the emergency SOS signal?
Type SOS as `... --- ...` (three dots, three dashes, three dots). It was adopted as the universal distress signal in 1906. Note that this tool is for learning and reference only and is not a means of actual emergency communication.
