Quick tip for beginners: Start with the word SOS — type it into the input box, press Play at 15 WPM, and listen to the pattern: · · · — — — · · · (three short, three long, three short). Once that pattern is in your ear, you know the most important Morse code sequence in existence. Press Repeat and listen until it is automatic.
How the timing works: A dot lasts 1 time unit. A dash lasts 3 units. The gap between signals within one character is 1 unit. The gap between characters is 3 units. The gap between words is 7 units. These ratios are precisely maintained in every audio file this translator generates.

Morse code is nearly 200 years old — and it is still in active use worldwide. Far from being a historical curiosity, it continues to serve critical functions in amateur radio, aviation, accessibility technology, emergency communications, and education. Here is where you will encounter it in the modern world.
Google added Morse code input to Android’s Gboard keyboard in 2018 for users with motor disabilities. A person who can control only a single switch — via head movement, sip-and-puff, or eye blink — can type full text using just two inputs: dot and dash. Morse code is one of the most efficient low-barrier text input methods ever designed.
Morse code is a merit badge subject for Boy Scouts and Girl Guides worldwide. Its binary structure — exactly two signal types encode the entire alphabet — makes it an intuitive entry point to encoding theory, signal processing, and the fundamentals of digital communication.
| Q-Code | As a Statement | As a Question |
|---|---|---|
| QSO | I can communicate with [station] | Can you communicate with [station]? |
| QTH | My location is… | What is your location? |
| QRM | I am experiencing interference | Are you experiencing interference? |
| QRN | I am troubled by static | Are you troubled by static? |
| QRZ | You are being called by… | Who is calling me? |
| QSL | I acknowledge receipt | Can you acknowledge receipt? |
| QRT | I am stopping transmission | Shall I stop transmitting? |
| QRQ | Send faster | Shall I send faster? |
| QRS | Send more slowly | Shall I send more slowly? |
| QRO | Increase transmitter power | Shall I increase transmitter power? |
| QRP | Decrease transmitter power (also: low-power operation) | Shall I decrease transmitter power? |
Q-codes are used internationally and are valid regardless of language. A German operator and a Japanese operator can exchange Q-codes in Morse without sharing a common spoken language.
History
Morse code was developed between 1836 and 1844 by the American inventor Samuel Finley Breese Morse and his assistant Alfred Lewis Vail. Their initial challenge was simple but profound: how do you transmit written language over an electric wire? The system they built assigned each letter and numeral a unique pattern of short and long electrical pulses — dots and dashes — that could be tapped out by an operator and decoded by another at any distance the wire could reach.
The original system Vail designed was not identical to the International Morse Code we use today. The original American Morse code had internal spaces, two different dash lengths, and was optimized specifically for English. In 1865, the International Telegraph Conference in Paris standardized a cleaner version — one dash length, no internal spaces, consistent timing ratios — that became the global standard. This International Morse Code is what this translator implements.
Morse code’s most famous moment came on April 15, 1912, when the RMS Titanic sank in the North Atlantic. The ship’s wireless operators sent the distress signal CQD and then the newly adopted SOS — · · · — — — · · · — which was received by the RMS Carpathia and prompted the rescue of 705 survivors. SOS was chosen not as an abbreviation for anything, but purely because its dot-dash pattern was unmistakable and impossible to confuse with any other signal.
Through the first half of the 20th century, Morse code was the backbone of global communications. Military operations in both World Wars depended on it. Merchant shipping, aviation, journalism, and diplomacy all ran on telegraph lines and radio transmissions in Morse code. Every naval vessel, every military unit, and every news agency had trained operators. During World War II, the ability to send and receive Morse at 20–25 WPM was a standard military skill with direct operational significance.
Digital communications gradually replaced Morse in commercial and naval use throughout the late 20th century. The GMDSS (Global Maritime Distress and Safety System) made Morse code no longer mandatory for maritime use in 1999. But rather than disappearing, Morse code migrated into amateur radio, where it thrives today as an operating mode valued for its ability to pierce weak signal conditions that defeat voice modes — a single carrier wave at any power level can make a contact that digital voice cannot.
The ITU (International Telecommunication Union) maintains the International Morse Code standard under Recommendation M.1677-1 to this day. The 1856 Russian Cyrillic standard and the 1942 Japanese Wabun code remain in use by their respective amateur radio communities. Morse code has now outlived the telegraph, the teletype, analog radio, and digital transition — and continues to evolve with new applications in accessibility technology, education, and gaming.

A dot (dit) is a short signal lasting 1 time unit. A dash (dah) is a long signal lasting 3 time units. The gap between signals within a single letter is 1 unit. The gap between letters is 3 units. The gap between words is 7 units. These timing ratios are defined by ITU-R Recommendation M.1677-1 and are the same worldwide.
A # appears when the input contains a character not included in the International Morse Code standard — such as an emoji, an accented letter (é, ñ, ü), or an unsupported symbol. Remove the flagged character and the rest of the translation will be unaffected.
Use a single space between letters and a / (space-slash-space) between words. Do not use double spaces. See the full input format guide above.
Farnsworth timing keeps characters at full speed but extends the gaps between letters and words. It is strongly recommended for beginners because it prevents a counting habit and trains direct audio-to-letter recognition. Set Farnsworth WPM lower than your character WPM to activate it.
CW (Continuous Wave) tone is the clean sine-wave beep used by modern amateur radio operators. Telegraph sounder is the original clicky mechanical sound of 19th-century telegraph equipment. Both are historically accurate; CW tone is used for Morse code practice and radio operation.
Prosigns are special procedural signals used in radio CW operation — sent as a single blended character. Common prosigns include AR (end of message), SK (end of contact), BT (break/separator), and the well-known SOS distress signal.
“PARIS” is the international benchmark word for measuring Morse code speed. At exactly 20 WPM, the word PARIS plus its trailing word-space takes 3 seconds to transmit. All WPM measurements on this tool use the PARIS standard per ITU specification.
Audio-to-text Morse decoding (uploading a sound file or using a microphone) is an advanced feature. The translator on this page generates and plays Morse audio. For audio input decoding, this requires a signal processing decoder — a feature in our roadmap.
The translator itself runs entirely in your browser and does not send data to servers. However, audio playback requires the Web Audio API, which is available in all modern browsers when online. An offline version is available by saving the page from your browser.
The ITU standard includes 18 punctuation marks: period (.), comma (,), question mark (?), apostrophe (‘), exclamation mark (!), forward slash (/), parentheses (( )), ampersand (&), colon (:), semicolon (;), equals sign (=), plus sign (+), hyphen (-), underscore (_), quotation mark (“), at sign (@), and dollar sign ($).
International Morse Code (ITU-R M.1677-1) is the worldwide standard and is used identically in every country for Latin-script languages. Some languages have their own Morse extensions: Russian uses a 33-letter Cyrillic standard (1856), Japanese uses Wabun code for katakana (1942), and Arabic has its own Morse mapping. This translator implements International Morse Code; dedicated tools for Russian and Japanese Morse are also available on this platform.
SOS — ... --- ... — three dots, three dashes, three dots. It is the international distress signal, recognized worldwide, and its pattern is the most memorable in Morse code. Type SOS into the translator and press Play at 15 WPM. Listen until the pattern is automatic. You will then know the most important Morse sequence in existence.
