Free Morse Code Translator
Translate text to Morse code and Morse code back to text instantly. Listen to your Morse code with adjustable speed (WPM) and tone (Hz), or watch it as visual light flashes. Supports the full International Morse Code alphabet including letters A-Z, numbers 0-9, and common punctuation. Translation, tone generation, and the flashing lamp are all produced locally by the page, and nothing you type is sent anywhere.
What is Morse Code?
Morse code is a character encoding system that represents letters, numbers, and punctuation as sequences of short signals (dots, or "dits") and long signals (dashes, or "dahs"). It was developed in the 1830s and 1840s by Samuel Morse and Alfred Vail for use with the electric telegraph, and it became the foundation of long-distance communication for over a century. The International Morse Code standard, established in 1865, is still used today by amateur radio operators, aviation, maritime navigation, and accessibility devices. Its simplicity makes it possible to transmit messages using sound, light, or even physical taps.
This free online Morse code translator converts plain text to Morse code and Morse code back to plain text in real time as you type. Beyond simple text conversion, it includes audio playback with adjustable speed (words per minute) and tone frequency (Hz), plus a visual light flash mode that displays each signal as a blinking lamp. The tool is useful for learning Morse code, encoding messages for fun, practicing for amateur radio exams, or building escape room puzzles. The whole translator lives in this single page, with no server round trips involved.
How to Use This Tool
- Type or paste text into the left panel to see it converted to Morse code instantly in the right panel. Alternatively, type Morse code (using dots and dashes separated by spaces, with / between words) in the right panel to decode it.
- Adjust the playback speed using the WPM (words per minute) slider and the audio tone using the Hz (frequency) slider in the controls bar.
- Click the Play button to hear your Morse code as audio beeps. Click the Flash button to enable the visual light mode, which shows a lamp that turns on for each dot and dash.
- Use "Copy Text" or "Copy Morse" to send either version to your clipboard. The reference chart below shows the complete International Morse Code alphabet.
Key Features
- Real-Time Translation - Converts text to Morse code and Morse code to text as you type, with no need to click a convert button. Changes appear instantly in the opposite panel.
- Audio Playback - Listen to your Morse code using the Web Audio API with customizable speed (5 to 40 WPM) and tone frequency (300 to 1000 Hz). Timing follows the PARIS standard for accurate dit and dah durations.
- Visual Light Flash - A lamp graphic flashes on and off in sync with the audio playback, displaying the current character and whether each signal is a dit or dah. This is great for visual learners.
- Complete Character Support - Supports all 26 letters (A through Z), all 10 digits (0 through 9), and common punctuation marks including period, comma, question mark, exclamation mark, slash, and more.
- Built-In Reference Chart - A complete Morse code reference table is displayed below the converter, organized by letters, numbers, and punctuation for quick lookup.
Frequently Asked Questions
What does WPM mean in Morse code?
WPM stands for words per minute and measures the speed of Morse code transmission. The standard reference word is "PARIS," which contains 50 dot-lengths. At 15 WPM, each dot lasts 80 milliseconds, and a dash lasts three times as long (240 milliseconds). Beginners typically start at 5 to 10 WPM, while experienced operators can send and receive at 25 WPM or faster.
How do I write Morse code manually?
Use a dot (.) for short signals and a dash (-) for long signals. Separate the dots and dashes within a single letter with no space. Use a single space between different letters and a forward slash (/) between words. For example, "HELLO" in Morse code is: .... . .-.. .-.. ---
Is Morse code still used today?
Yes. Morse code is still actively used by amateur (ham) radio operators worldwide, in aviation for navigational aids (NDB and VOR beacons transmit their identifiers in Morse), and in some military and emergency communication scenarios. It is also used as an assistive technology, allowing people with limited mobility to communicate by blinking, tapping, or using a single switch.
What is the most famous Morse code signal?
The most well-known Morse code signal is SOS (... --- ...), the international distress signal. It was chosen not because the letters stand for anything, but because the pattern of three dots, three dashes, and three dots is easy to recognize and hard to confuse with other sequences. It was first adopted in 1906 and remains universally understood.
