Morse Code Translator

Morse Code Translator — Convert Text to Morse Online, Free

Type any text and watch it transform into dots and dashes instantly. Play it back as audio with adjustable speed, watch it flash visually, tap it on your keyboard, and test your knowledge with the built-in quiz — all in one place, no account needed.

The Morse Code Translator handles the full International Morse Code standard: all 26 letters, digits 0–9, and common punctuation. Translation works both ways — enter Morse to decode it back to plain text in real time.

How to Use the Morse Code Translator

Converting text to Morse code takes seconds:

1. Type your message in the plain text panel — the Morse output appears instantly in the right panel as you type, using standard dots (·) and dashes (−) separated by spaces, with slashes (/) between words.
2. Play the audio by clicking Play Audio — the tool beeps each symbol at your chosen speed (WPM) and frequency (Hz), giving you an accurate representation of how the message would sound on the air.
3. Switch modes using the Text → Morse / Morse → Text toggle to decode: paste dots and dashes in the Morse panel and the decoded text appears in the left panel.
4. Copy the output with the copy button or press Shift+Enter anywhere on the page to copy the Morse output to your clipboard.

Morse Code Examples

Decoding example:

Input:  .- -... -.-.
Output: ABC

Edge case — unknown character: Any character without a Morse equivalent (e.g., accented letters) outputs ? so you can see exactly where the gap is without silent failures.

What Is Morse Code?

Morse code is a communication system that encodes each letter, digit, and punctuation mark as a unique sequence of short signals (dots) and long signals (dashes). Samuel Morse and Alfred Vail developed it in the 1830s alongside the electric telegraph — the first technology capable of transmitting messages faster than a physical carrier could travel.

The system that spread worldwide is the International Morse Code (ITU Morse), standardized in 1865 and still the version in use today. It replaced the original American Morse code, which used different gap lengths and is rarely seen outside historical contexts.

Timing in Morse code follows strict ratios: a dot lasts 1 unit, a dash lasts 3 units, the gap between elements in a letter is 1 unit, the gap between letters is 3 units, and the gap between words is 7 units. This is why Morse has a distinct rhythm — and why experienced operators can identify a sender's style ("fist") even without seeing the message.

Flash Mode — Visual Morse Signaling

The flash mode displays your message as light pulses, mimicking the way signal lamps work in naval and military communication. A bright flash represents a signal (dot or dash); darkness represents a gap. Timing follows the standard Morse ratios exactly.

On mobile, this makes the screen function as a visual signal lamp — useful when you need silent signaling or want to practice reading Morse by sight instead of sound. This capability is what distinguishes Morse from digital text in genuine low-bandwidth emergency scenarios.

Tap Mode — Enter Morse by Touch

Instead of typing dots and dashes, tap to produce them: a short tap enters a dot (·), holding for more than 300ms enters a dash (−). After 600ms of silence the current letter is committed to the decoded output.

This is how radio operators and Morse learners traditionally practice: the muscle memory of tapping is a separate skill from reading, and it locks in the rhythm of each character far better than visual copying.

Common Use Cases

• Ham radio training: CW (continuous wave) Morse is still a common mode on amateur radio bands. Use the speed slider (5–40 WPM) and Farnsworth-style pacing to train your ear before getting on the air.
• Puzzle and escape rooms: Create or decode Morse messages for game design, geocaching waypoints, and puzzle hunts.
• Learning by quiz: The built-in quiz plays a random Morse sequence and asks you to identify the letter, tracking your score to show which characters you've mastered.
• SOS signaling: The SOS Quick button plays the emergency signal (... --- ...) immediately. The visual flash mode works as a silent phone-screen signal for situations where sound is not possible.
• Pop culture and curiosity: Decode "meu nome em código morse," match a Stranger Things scene, or convert your name to share with friends.

SOS — What It Really Means in Morse Code

SOS in Morse code is ... --- ... — 3 dots, 3 dashes, 3 dots, sent as a continuous run without the normal letter gaps. It was adopted as the international maritime distress signal in 1908.

SOS is not an acronym. It does not stand for "Save Our Souls," "Save Our Ship," or any other phrase. The sequence was chosen purely because it is the simplest possible pattern to recognize in a noisy signal: three of one, three of the other, three of the first again. No other Morse sequence is as symmetrical or unmistakable.

In 1912, the Titanic used CQD (the older British distress call) and then SOS — the incident that established SOS as the global standard. The Global Maritime Distress and Safety System (GMDSS) replaced mandatory shipboard Morse in 1999, but SOS remains the recognized visual distress signal worldwide.

Frequently Asked Questions

What does SOS mean in Morse code?

SOS is ... --- ... (3 dots, 3 dashes, 3 dots). It is the international emergency signal adopted in 1908, chosen because the pattern is uniquely simple and impossible to mistake in a noisy signal. SOS is not an acronym — no phrase was ever attached to the letters.

Is Morse code still used today?

Yes, in several active contexts: amateur (ham) radio operators worldwide transmit CW Morse — some countries still require Morse proficiency for licensing. Google's Gboard keyboard offers Morse code input for users with motor disabilities, making it a live accessibility technology. Naval and military systems retain Morse as a backup communication mode.

How do I decode Morse code back to text?

Switch to the Morse → Text mode using the direction toggle. Enter dots and dashes separated by a space between each letter, and use / (space-slash-space) between words. The decoder converts the pattern to plain text in real time.

Does the translator support numbers and punctuation?

Yes. All 10 digits (0–9) and common punctuation marks (period, comma, question mark, exclamation, slash, at sign, and more) are supported using the International Morse Code standard assignments.

What is WPM in Morse code?

WPM (Words Per Minute) measures transmission speed using the word "PARIS" as the standard — 50 elements long, which at 1 WPM takes exactly 1 minute. Beginners typically learn at 5–10 WPM; conversational ham radio speed is 15–20 WPM; competition-level operators reach 30–40 WPM.

What is the Farnsworth method for learning Morse?

The Farnsworth technique sends each individual character at full speed (e.g., 20 WPM) but inserts extra-long gaps between characters and words, bringing the effective message speed down (e.g., 10 WPM). This forces your brain to recognize each character as a sound pattern rather than counting individual dots — the key skill for moving beyond beginner speed.
