Morse Code Converter
Free Morse code converter and translator online. Convert text to Morse code and decode Morse back to text directly in your browser. Supports letters, numbers and punctuation. No sign-up required.
About this tool
This Morse Code Converter allows you to transform any text into Morse code signals (dots and dashes) and decode Morse code sequences back into plain text. All processing happens directly in your browser, with no data sent to external servers. Also known as a Morse code translator or Morse alphabet converter, this tool is useful for students, amateur radio operators, scouts, hobbyists, and professionals who work with internationally standardized Morse code.
Conversion works both ways: type a word and get the corresponding dot-and-dash sequence, or paste a Morse code message and read the decoded text. You can also listen to the result as audio with the correct timing of dots and dashes, making it ideal for anyone learning to recognize Morse code by ear. The tool supports letters from A to Z, digits from 0 to 9, and the main punctuation marks defined by the international standard.
Key Features
What Is Morse Code
Morse code is a communication system that represents letters, numbers, and punctuation using sequences of short and long signals, commonly known as dots and dashes. Each character has a unique combination of these signals, allowing messages to be transmitted through sound, light, radio, or even tapping on a surface.
Its main characteristic is simplicity. Unlike many other encoding systems, Morse code requires only two states: on and off, short and long. This makes it extremely reliable in adverse conditions. A Morse code message can still be understood through background noise, weak radio signals, or low visibility — situations where spoken communication may fail.
How Morse Code Works
Each element of Morse code has a precise duration. A dash lasts three times longer than a dot. The gap between dots and dashes within the same letter equals one dot. The gap between letters equals three dots, and the gap between words equals seven dots. This timing ratio allows experienced operators to read Morse code at surprisingly high speeds, recognizing the rhythm even before identifying individual characters.
In written form, as used in this tool, letters are separated by a single space and words are separated by a slash (/). The FAQ below includes practical examples showing how this convention works when converting real phrases.

Where Morse Code Is Used Today
- Amateur radioAmateur radio is the primary modern use of Morse code today. Operators around the world communicate on shortwave frequencies using CW (Continuous Wave) mode, which is essentially Morse code. For many enthusiasts, it is both a tradition and a technical skill. There is also a practical advantage: CW signals can travel through interference and across very long distances using extremely low power, something voice communication often cannot achieve.
- AviationRadio beacons and navigation stations still transmit their identifiers in Morse code, repeating the station letter sequence every few seconds. Pilots are trained to recognize these patterns and confirm that they are tuned to the correct frequency.
- Military communicationsMilitary organizations continue to maintain Morse code as a backup communication method in situations where digital radio systems may fail or be intercepted. The ability to transmit messages using improvised equipment is considered a strategic advantage.
- AccessibilityPeople with severe motor impairments use Morse code adaptations to communicate. With a single button press or even an eyelid movement, it is possible to write complete words, and many modern accessibility applications are based on this principle.
- Scouting and educationMany scout groups teach Morse code as part of their communication and signaling activities, helping preserve a practical and historically important skill.
- Emergency situationsThe SOS signal (three dots, three dashes, three dots) is universally recognized. People in remote areas have used flashlights, mirrors, and fires to send Morse code distress signals, and rescue teams are trained to identify these sequences.

Frequently Asked Questions
American Morse, also known as the original Morse code, was the version created by Samuel Morse for railroad telegraph systems in the United States. It used internal pauses in some letters, which made radio transmission more difficult. International Morse, standardized in 1865, removed those pauses and simplified several characters, eventually becoming the worldwide standard. This tool uses the international standard.
The easiest way is to use a tool like this one: type your text and copy the generated Morse code. To actually transmit the signal, some apps can convert text into sounds or flashlight pulses, reproducing the correct dot-and-dash rhythm.
The international Morse code standard does not include accented characters. This tool automatically removes accents before conversion, so 'café' becomes 'CAFE'. Characters outside the Latin alphabet, digits, and supported punctuation marks are replaced with '?'.
For basic recognition at speeds between 5 and 10 words per minute, most people need four to eight weeks of regular practice, usually around 15 to 30 minutes per day. Reaching fluent conversational speeds above 20 words per minute can take anywhere from six months to a year.
In audio transmission, words are separated by a pause equal to seven dots. In written form, letters are separated by a single space and words are separated by a slash (/). For example, 'HI YOU' becomes .... .. / -.-- --- ..-
A common misconception is that SOS stands for 'Save Our Souls' or 'Save Our Ship'. In reality, the letters were chosen not for their meaning, but for the simplicity of the sequence: three dots, three dashes, and three dots, with no pauses between letters. This pattern is easy to transmit, difficult to confuse with other messages, and recognizable even under poor conditions. The signal was adopted as the international maritime distress standard in 1908, replacing the older CQD signal used by the Marconi Company. In 1912, the sinking of the Titanic helped popularize SOS worldwide, although the ship's operators transmitted both CQD and SOS that night.
The tool supports all Latin alphabet letters from A to Z, digits from 0 to 9, and the most common punctuation marks defined by the international standard, including periods, commas, question marks, exclamation marks, parentheses, the at sign, and others. Characters outside this set are replaced with a question mark in the output.
