Decide which way you are converting. Text → Morse turns readable words into dots and dashes; Morse → Text does the reverse. Letters, digits, and common punctuation are all supported, following the International Morse standard.

Every letter of English has a Morse equivalent — a short pattern of dots and dashes fixed by the international standard ITU-R M.1677 — but looking each one up in the Morse code alphabet and assembling a message by hand is slow, and one swapped signal quietly changes the word. This free Morse code translator does the conversion for you: type or paste English and read clean Morse instantly, or paste dots and dashes to decode them back into readable text. Playback with adjustable speed, copy tools, and a full A–Z chart are built in — and there is nothing to sign up for.
Upload a recording of Morse code — WAV, MP3, OGG or M4A — and this decoder finds the tone, times the dits and dahs, and turns them back into text, right in your browser.
Honest note: this works best on clean, steady, machine-generated tones — like a WAV exported from the translator above. Noisy recordings, music in the background, or uneven hand-keyed Morse may decode imperfectly. Your file is processed entirely on your device and is never uploaded anywhere.
Watch the translator turn HELLO into real Morse code — dots, dashes and sound — in 42 seconds.
Morse timing works in fixed proportions. A dot is the base unit; a dash stretches to three units; the elements inside one character sit one unit apart; characters are divided by three units of quiet and words by seven. Those ratios, not the raw speed, are what separate one letter from the next — and they are exactly what the translator applies when it plays your message aloud. Our Morse code timing guide walks through each gap in turn.

Morse code is a way of writing language as rhythm: short signals (dots) and long signals (dashes) stand in for letters, digits, and a handful of symbols. Samuel Morse and Alfred Vail built it for the electric telegraph in the 1830s; the ITU later fixed the international version, and more than 180 years on it still serves in aviation, shipping, amateur radio, and emergency signaling. Our full guide to what is morse code traces that history and shows where the code turns up today.
Learn More About Morse CodeThe short element — one unit of signal, spoken as “dit” at the end of a character.
The long element — three units of signal, spoken as “dah.”
Silence is information too: the length of a gap tells a listener where elements, letters, and words divide.
Played as tones, the same patterns become rhythm, which is why operators learn the code by ear.
Turns plain English into International Morse, character by character.
Reads a string of dots and dashes and returns the words inside it.
Applies the standard gaps so letters and words stay separate.
There is a reason the code rewards study beyond nostalgia. Learning it sharpens listening, memory, and pattern-spotting, and it gives you a way to signal with nothing but a torch, a buzzer, or a knock on a wall. Start anywhere: E, the commonest letter in English, is a single dot.
Four short steps take you from a blank box to a finished translation. Pick a direction, add your text or your dots and dashes, check the result with the playback controls, then copy it or save the audio — the whole round trip usually takes under a minute.
Decide which way you are converting. Text → Morse turns readable words into dots and dashes; Morse → Text does the reverse. Letters, digits, and common punctuation are all supported, following the International Morse standard.
Type your message, or paste one you found, into the input box. The translation builds as you type, and if a character has no Morse equivalent it is named for you, so nothing vanishes silently from the result.
Press play to hear the signal as tones, slow it down or change its pitch, or switch on the light and vibration modes to feel the pattern instead. Hearing a character as one rhythm is what makes it stick.
Copy the finished translation with one click, flip the direction to check it converts back cleanly, or save the sound as a WAV file to practise away from the page.
Five everyday words, translated. Drop any of them into the tool, flip the direction, and watch the same patterns come back as text — a quick way to confirm the translator reads spacing the way you expect.
Keep this table open while you work. It lists every letter, digit, and supported punctuation mark in International Morse — handy for checking one stubborn character, spelling your name in code, or confirming a pattern before you send it.

People often search for a “Morse font,” but Morse is not a typeface — it is a code, and every character owns one fixed sequence of dots and dashes. This section explains how a character, its pattern, and the translated result fit together; the dedicated alphabet page carries the complete list.
One letter, digit, or punctuation mark from the standard set.
The dot-and-dash sequence the ITU assigns to that character.
What the tool above produces when it converts in either direction.
Everything here is built around one job — turning text into Morse and back without friction. Instant conversion both ways sits alongside playback you can slow down, a light that flashes the signal, settings for speed and pitch, and a WAV export for practice away from the screen.
A live character count in the input box, so long messages never catch you by surprise.

Load a ready-made phrase when you want to test the tool before trusting it with your own words.
Hear your message as a proper Morse signal, sent with correct timing at any speed you choose.
Watch the same signal as flashes of light — useful for visual practice and silent signaling drills.
Set the words-per-minute rate, tone pitch, volume, and repeat behaviour to suit your ears.
Export the sound of your message as a WAV file for lessons, puzzles, or offline drills.
The fastest way to learn the code is to use it. Type a word you care about — your name, your street, your dog — then study how each letter's pattern sounds, and let the translator check your guesses as you start writing Morse unaided.
Think of each character as a tiny piece of music. Played aloud, a dot is a blip and a dash is a held note; shown in light mode, the same contrast becomes short and long flashes you can read across a dark room.
On phones and tablets you can also tap the signal out yourself or feel it through vibration, where the device supports it. None of this needs an account — the practice tools are simply part of the page.
Conversions happen in your browser the moment you type; nothing waits on a server.
Slow the playback down, set a pitch you like, and loop a phrase until its rhythm feels familiar.
Sound, light, vibration, and tapping give your brain four different doors into the same patterns.
Charts train the eye, but fluent operators recognize characters the way you recognize a voice — instantly, by sound. Our guided path teaches you to learn morse code by ear: characters arrive at honest speed with breathing room between them, in short daily sessions with drills that build one rhythm at a time.
Nearly every bad translation traces back to one of three habits: dropping an element, stretching or squeezing the timing, or losing the gaps that separate characters and words. All three are fixable once you know to look for them.
One forgotten dot garbles the character and the word around it. When a decode reads strangely, re-check the raw signal before blaming the chart.
Key too eagerly and a dot stretches into a dash. Practising slowly, at a speed you can hold steady, builds timing your hands can trust.
Let the gaps collapse and two letters fuse into a third. Keep the inside of a character tight, the space between characters clear, and the word gap unmistakably longer.
The code grew up with the electric telegraph in the 1830s, in the workshop of Samuel Morse and his collaborator Alfred Vail. Their early system crossed the Atlantic world within a generation, and in 1865 an international conference in Paris settled the version — International Morse — that radio still uses.
Morse and Vail build a working telegraph and a code to run on it, assigning the shortest patterns to the letters English uses most.
The first public line opens between Washington, D.C. and Baltimore, carrying the biblical line “What hath God wrought?”
Delegates in Paris adopt a common international alphabet, the direct ancestor of the ITU standard this translator follows.
That 1844 demonstration was only the start of the story. How a single wire's code spread worldwide — and why it outlived the telegraph itself — is told in our guide to what is morse code.
Reading Morse means working in two passes: split the signal into characters using the gaps, then match each pattern to its letter. Writing it is the mirror image — take the text one character at a time and lay down its pattern, keeping your timing even so the reader's two passes stay easy.
Written Morse has a tidy convention for those gaps: one space between the letters of a word, and a slash where a word ends. So .... .. / - .... . .-. . is “HI THERE” — two words, seven letters, no ambiguity. Listening works the same way at speed: a brief pause closes a letter, a longer one closes a word, and experienced ears hear the words whole rather than spelling them out letter by letter.
Sound-first learning means treating every character as a rhythm to recognize, not a puzzle to count. Play a letter in the translator, say its rhythm back, and add new characters only when the old ones answer instantly — that is how operators have trained for a century.
A loop that works: listen, tap, listen, tap. Tapping the pattern on a desk fixes the contrast between a crisp dot and a full dash in your hands as well as your ears. And Morse asks for no special equipment — tone, light, knocks, and radio static have all carried it faithfully.
Five or six high-frequency letters cover a surprising share of real words; begin there, not at A.
Hear the whole character as one sound before you ever count its elements.
Drumming the pattern on a table locks the timing into muscle memory.
Raise the pace only when accuracy holds — speed built on guessing collapses.
On air, Morse is pure rhythm — a stream of short and long tones in which the silences carry as much meaning as the sounds. The playback above lets you live inside that rhythm at whatever speed your ear can handle today.
The more you listen, the less you translate: characters stop being dot-dash puzzles and start arriving as single, recognizable sounds. Ragged timing is the usual reason a signal feels hard to copy, so work through the Morse Code Sounds page for ear training and the Morse Code Timing guide for the spacing rules behind clean sending.
By the end of this page you will hold the whole foundation: what dots and dashes are, which letters matter most, how the three kinds of gap work, and how a character sounds as a single rhythm. The linked guides then take each skill deeper.
The only two elements in the system — one short, one long, always in a three-to-one ratio.
E, T, A, O, I, N, S, and H do most of the work in English, and Morse gives them the shortest patterns.
Element, letter, and word spacing follow the one-three-seven unit pattern.
Fluent copying means hearing a character whole, the way you hear a word instead of its letters.
Reach for the translator whenever a message needs to become Morse — or a string of dots and dashes needs to become words again. People use it to check patterns, build lessons and puzzles, prepare amateur-radio practice material, and settle arguments about what a signal says. For genuine emergencies, always use official emergency services, not a code.
The original home of the code: wires, keys, and operators copying by ear at speed.
On the amateur bands, Morse — called CW — still threads weak signals through noise that swallows speech.
Torches, lamps, and flags can all carry short-long patterns; navies once ran whole conversations this way.
An LED and a buzzer speak Morse fluently — handy when a prototype has no screen to complain on.
Clubs, scouts, and classrooms use the code to drill listening, memory, and careful sending.
Switches, taps, and blinks turn Morse into an input method, and its history anchors lessons on encoding.
However you use it, treat Morse as a skill and a hobby with a long history — never as a substitute for calling emergency services.
Retired from the telegram office, Morse never actually left. It persists where a simple, robust signal beats a rich one — and it has picked up second lives in design, teaching, and assistive technology along the way.
Beads and bars on a bracelet can spell a name or a private word in dots and dashes.
A row of dots and dashes carries a date or a motto only the wearer can read at a glance.
Teachers use the code to make encoding, timing, and information tangible for students.
One or two switches are enough to write in Morse, which keeps it relevant in access technology.
Amateur operators still choose CW for long-distance contacts on very little power.
Radio beacons have long identified themselves in Morse, and pilots still confirm beacon IDs by ear.
Puzzle hunts, escape rooms, and geocaches lean on Morse because anyone can verify the answer.
Armies signalled in Morse for over a century; its procedures shaped modern radio discipline.
A torch flashing SOS is understood almost everywhere — though responders and official beacons remain the real rescue system.
Designers hide Morse in games and trailers because decoding it feels like cracking a genuine secret.

Nearly two centuries old, the code keeps turning up in places nobody planned — including another planet.
On 24 May 1844 the first American telegraph line carried a line from the Book of Numbers — “What hath God wrought?” — from the Capitol in Washington to a Baltimore railway depot.
The wheels of NASA's Curiosity rover are cut so their tracks stamp “JPL” (.--- .--. .-..) into Martian dust — a rolling signature from the Jet Propulsion Laboratory.
For years the world's commonest text alert, Nokia's “Special” tone, simply spelled SMS (... -- ...) — so millions of people heard Morse code every day without knowing it.
Two codes share the Morse name. American Morse came first, on United States landlines; International Morse — revised under Friedrich Gerke's influence in Germany and adopted in 1865 — simplified it for radio and world telegraphy. Everything on this site, translator included, uses the international system.
The differences are practical, not cosmetic: several letters have different patterns in the two systems, and American Morse even used spaces inside some characters, which a radio carrier could not send reliably.
| Topic | International Morse | American Morse |
|---|---|---|
| Historical context | World telegraphy, then international radio communication | Early United States landline networks |
| Modern role | The living standard — the one this translator uses | Kept by historians and landline enthusiasts |
| Character patterns | Fixed by ITU-R M.1677; no spaces inside characters | Some letters differ; a few contain internal spaces |
| Timing | Strict one-three-seven unit spacing | Looser conventions, with extra in-character gaps |
Other languages folded the international framework around their own alphabets. Russian operators, for instance, map the same patterns onto Cyrillic letters and add a few extra signs for sounds Latin lacks. It is a useful reminder that Morse was never one frozen alphabet — it is a method that each language adapts.
Read a Morse pattern backwards and something curious often happens: another letter appears. The table below pairs characters with their reversals — a memory aid operators have used for generations, since learning one member of a pair gives you the other at half price.
| Character | Pattern | Character match | Reversed pattern |
|---|---|---|---|
| A | .- | N | -. |
| B | -... | V | ...- |
| D | -.. | U | ..- |
| F | ..-. | L | .-.. |
| G | --. | W | .-- |
| Q | --.- | Y | -.-- |
| K | -.- | K | -.- |
| R | .-. | R | .-. |
| S | ... | S | ... |
| T | - | T | - |
Prosigns are the code's control keys: short procedural signals, sent as if their letters were run together with no gap, that manage the conversation itself — opening it, closing it, asking the other side to wait. You will hear them constantly on the amateur bands.
| Prosign | Pattern | Typical meaning |
|---|---|---|
| AR | .-.-. | End of message — I have finished sending this one. |
| SK | ...-.- | End of contact — signing off for good. |
| BT | -...- | A break between sections of a message, like a paragraph mark. |
| AS | .-... | Wait — stand by while I pause or check something. |
Q-codes are three-letter shorthand born in early radio, when every character cost time. Each one stands for a whole question or statement, and they work in voice as happily as in Morse — which is why pilots and sailors still use several of them.
“What is your location?” — answered with a place or coordinates.
Interference caused by other stations crowding the frequency.
Static and natural noise making copy difficult.
“Send more slowly, please.”
“I am stopping transmission.”
“Who is calling me?”
“I confirm receipt” — also the cards operators exchange to prove a contact.
A two-way radio contact; the basic unit of amateur conversation.
Four controls shape how the signal reaches you. Set them once for comfort — a pitch your ears like, a speed you can honestly copy — and the same settings will quietly improve every practice session that follows.
Sets the words-per-minute rate of playback. Learn slow and steady; raise it as accuracy improves.
Moves the tone up or down in pitch. Most operators settle somewhere in the middle range for long listening.
Playback loudness — keep it modest, especially through headphones on long sessions.
Loops the current message so you can copy it again without touching the controls.
Speed in Morse is quoted in WPM — words per minute. It is not a cosmetic setting: because timing is part of the code, turning the speed up shrinks every dot, dash, and gap together, and the rhythm of each character survives intact.
The yardstick is the word “PARIS,” which occupies exactly fifty time units including its trailing word gap. Twenty WPM therefore means a pace at which PARIS would be sent twenty times in a minute, and the translator's speed control follows that same convention.
Beginners often start near five WPM, slowly enough to count elements. Around twelve to fifteen, counting gives way to recognizing whole characters; twenty is an easy conversational pace on the bands; contest operators work past forty, where signals fuse into pure rhythm. Farnsworth timing bridges the gap — characters keep their brisk, true shape while the spaces between them stretch, so your ear learns honest rhythms at a gentle overall speed.
That is the setting strategy this translator rewards: keep character speed realistic, lean on the gaps while you learn, and close them as recognition firms up. Chasing a high WPM number before the characters are automatic only trains faster guessing.
The primary sources behind this page — the ITU's own recommendation defining the code, plus background on SOS and standardized timing — repay an evening if the subject has caught you.
Read the ITU recommendationThe Titanic's Marconi operators sent both the older CQD and the new SOS on the night of 14–15 April 1912. SOS won its place not as an acronym — it stands for nothing — but because ... --- ... is unmistakable through static and panic alike.
Read the SOS guideWhen a translation looks wrong, the fault is almost always in the input rather than the tool. Work through these four checks in order — character support, spacing, then your audio settings — before assuming the code itself is misbehaving.
The input held nothing the tool recognizes. Check for stray symbols, emoji, or letters from alphabets outside the standard set.
Look at the gaps first. One missing space merges two characters into a different pattern, and one extra space splits a character in two.
Move the pitch toward the middle of its range, set a comfortable volume, and try headphones in a noisy room.
Lower the WPM until you can copy without guessing, then step it back up gradually over several sessions.
You now have the complete toolkit: a translator that converts both ways, the timing rules underneath it, and guides for the alphabet, the sounds, and the learning path. Put a real message through the tool — your name is a fine start — and check it by ear.
From there, keep going with the alphabet, timing, sounds, and learning guide pages as your skills grow.
Short answers to the questions this translator hears most — what it does, what it costs, what it accepts, and how the timing underneath it works.
It is a tool that turns written English into International Morse code — the dot-and-dash system standardized as ITU-R M.1677 — and turns Morse back into plain text. Type in one direction and the other appears instantly, so you never have to look up patterns letter by letter or assemble a message by hand.
Yes — every part of it is free, with no account and no usage cap. You can encode and decode as much text as you like, play the audio, change speed and pitch, copy results, and save WAV files. Conversion happens in your browser, so the words you type stay on your own device.
It covers the complete International Morse repertoire: letters A through Z, the digits 0 to 9, and everyday punctuation like full stops, commas, question marks, and apostrophes. Anything outside the standard is reported on screen rather than quietly skipped, which keeps the output trustworthy. The alphabet page lists every supported character.
Swap the translator into Morse → Text mode, then paste your sequence using a full stop for each dot and a hyphen for each dash. Leave one space between letters and a slash between words, and the English reading appears as you type, ready to copy, play aloud, or translate back again.
A dot lasts a single time unit and a dash lasts three, with one unit of silence between the elements inside a character. Characters are separated by three units and words by seven. Those proportions, set down in the ITU standard, are what let a listener — or this translator's audio — tell one letter from the next.
SOS is written ... --- ... — three dots, three dashes, three dots. Chosen in 1908 as the international distress signal because the pattern is almost impossible to confuse with anything else, it is a prosign rather than an abbreviation. Paste it into the translator above and press play to hear the rhythm.
