About Us
Just Morse is a small, independent Morse code translator and practice space. We built it so anyone can encode, decode, listen, and learn — without giving up their messages.
Our story
Morse code is one of the oldest digital languages still in use. It is spare, rhythmic, and surprisingly expressive — two signal lengths and a handful of silences, invented in the 1830s for the electrical telegraph and still spoken by amateur radio operators, mariners, aviators, and anyone who likes sending a secret in plain sight.
Most online translators treat that language as a cloud problem: you type, a remote server converts, and you hope nothing sensitive was in the box. That is a strange bargain for a code designed to travel without a middleman.
Just Morse takes the other path. The translator, audio engine, and signal lamp run entirely in your browser. Encode English to Morse, decode dots and dashes back to text, hear the tones, watch the lamp — none of that leaves your device. There is no account, and there is no message inbox on our side, because we never receive the message.
A translator alone is useful for a minute. Learning Morse takes longer. So we added a full reference chart, pages for letters, numbers, and common phrases, and a lesson path that teaches you to read dits and dahs rather than memorize printed pictures of them. Progress stays in your browser, next to your theme preference — useful on this computer, invisible to us.
We are a small independent project, not a platform. The aim is simple: a calm, accurate tool that treats Morse with respect and treats your text the same way.
What we built
Three parts of the same idea: look a signal up, hear it, then keep practicing until it is yours.
Two-way conversion as you type. Play authentic telegraph tones, adjust speed (WPM), pitch, and volume, and flash the same rhythm on a signal lamp. Copy the result or grab a shareable link — still without uploading the text.
Open the translatorStart with E and T, then work through the alphabet, numbers, punctuation, and real copy — words, callsigns, and Q-codes. Each drill plays Morse first. You type what you heard. Progress never leaves this browser.
Browse lessonsA complete Morse chart sits on the homepage. Dedicated pages cover every letter and digit, plus phrases people actually look up — SOS, hello, I love you — so you can see, hear, and share a signal in one place.
View the Morse chartThe code
Pretty dots on a screen are not enough. If the sound is wrong, it is not Morse — it is a ringtone.
The short signal. One unit of time — the heartbeat everything else is measured against.
The long signal. Three times a dit, so your ear can tell them apart even at speed.
One dit between elements, three between letters, seven between words — the silence is part of the code.
International Morse (the ITU standard) is a timing system as much as an alphabet. A dah is three dits long. The gap inside a character equals one dit; the gap between characters equals three; the gap between words equals seven. Just Morse uses those ratios for both the audio you hear and the lamp you watch, so practice transfers to real transmissions instead of fighting them.
Speed is measured in words per minute. Eighteen WPM is a comfortable default for learning; you can slow down to study a new character or push faster as your ear catches up. Pitch defaults to a classic telegraph tone around 600 Hz, and you can change it if another note is easier to live with.
Tones are built with the Web Audio API in your browser. Nothing is streamed from a server, so playback still works after the page has loaded — even on a shaky connection.
The signal lamp flashes with the same timing as the sound, which helps if you are learning to read Morse by sight — or practicing in a quiet room.
Privacy
Whatever you type into the translator — a joke, a callsign, a line of homework, a private note — is processed on this device. We do not operate a backend that receives that text. There is nothing for us to log, because it never arrives.
Lesson progress and your light/dark preference live in local browser storage. Clear the site data and they disappear. Switch computers and they will not follow you. That is a trade-off we accept so practice does not require an account.
The one third-party measurement we use is Google Analytics, which helps us see which pages are useful. It does not receive the contents of the translator or your lesson answers. Details, and how to opt out, are in the Privacy Policy.
Who it's for
You do not need a radio license to use Just Morse. You only need curiosity — or a message that wants a different shape.
Studying for a license or brushing up on-air copy? Hear characters at a speed you choose, then practice until the rhythm sticks.
Morse is a memorable way to explore codes, timing, and the alphabet. The translator and lessons work on a phone, tablet, or classroom computer.
Encode a greeting, an SOS, or a secret in plain sight. Copy the result, play it aloud, or watch it flash from the signal lamp.
No account, no feed, no upload. Just Morse is for people who want a precise utility that stays out of the way.
A few simple promises that shape every page of Just Morse.
Encoding, decoding, and audio all run on your device. Your messages are never uploaded, stored, or sent to a server.
Timing follows ITU Morse standards so the tones and flashes you hear match real-world telegraph practice.
Lessons, a full chart, and popular phrases help you go from curious visitor to confident copy — at your own pace.
No sign-up wall, no paywall, no clutter. Just a calm tool for translating and practicing Morse code.
