Frequently Asked Questions
How do I translate text to Morse code?
Select the 'Text → Morse' mode and type your message. The Morse code translation appears instantly as you type — each letter is converted to its dot-and-dash pattern, with spaces between letters and slashes between words.
How do I decode Morse code to text?
Select the 'Morse → Text' mode and type or paste your Morse code. Use dots (.) for short signals and dashes (-) for long signals. Separate letters with spaces and words with a forward slash (/). Example: '.... . .-.. .-.. --- / .-- --- .-. .-.. -..' decodes to 'HELLO WORLD'.
What is SOS in Morse code?
SOS in Morse code is ··· ——— ··· (three dots, three dashes, three dots, or ... --- ... in this tool). It's the international distress signal, chosen because it's simple, unmistakable, and easy to transmit even under stress. You can type 'SOS' in the tool to see and hear it.
What characters does Morse code support?
International Morse code supports all 26 letters (A-Z), numbers 0-9, and common punctuation including period, comma, question mark, exclamation mark, slash, parentheses, colon, semicolon, equals sign, plus, minus, underscore, quotation marks, dollar sign, and at sign.
How does the audio playback work?
The Play button generates real-time audio tones using the Web Audio API. Short beeps represent dots and longer beeps represent dashes, with proper timing gaps between characters and words following international Morse code standards. A green signal light blinks in sync with each tone.
What are the dots and dashes in Morse code?
A dot (·) is a short signal and a dash (—) is a long signal, typically three times the length of a dot. Each letter and number has a unique pattern. For example: A is ·— (dot dash), B is —··· (dash dot dot dot), and E is just · (a single dot, the shortest letter).
How do I write my name in Morse code?
Select 'Text → Morse' mode and type your name. The tool instantly converts each letter to its Morse code equivalent. You can then copy the result or play it as audio. For example, 'SAM' becomes '... .- --'.
Is Morse code still used today?
Yes. Morse code is actively used in amateur (ham) radio, aviation navigation aids (NDBs and VORs), military communication, emergency signaling, and accessibility tools for people with limited mobility. It's also popular in escape rooms, puzzle games, geocaching, and as an educational tool.
Can I learn Morse code with this tool?
Yes. Use the slow speed audio playback to practice hearing each letter. The reference chart shows every character's Morse code pattern. Try typing familiar words and listening to them, then switch to decode mode and practice reading Morse code back to text.
What speed should I use for Morse code playback?
Slow speed is best for beginners learning to recognize individual letters. Medium speed is standard for general use. Fast speed is for experienced operators or quick playback. You can switch speeds anytime without restarting.
Does this tool work offline?
Yes. Once loaded, the Morse code translator works completely offline — all translation and audio generation happens in your browser. No data is sent to any server.
How do I copy the Morse code translation?
Click the Copy button in the output area header. The translated Morse code (or decoded text) is copied to your clipboard instantly. You can paste it anywhere — messages, documents, social media, or other tools.
