Morse code was invented by Samuel Morse and Alfred Vail in the 1830s for telecommunication over telegraph lines. Today, Morse code remains a fundamental skill in amateur radio (ham radio), aviation, marine emergency signaling (SOS: `... --- ...`), and military communications. Our browser-native Morse Code Converter translates English letters, numbers, and punctuation into standard International Morse Code strings instantly. You can also paste raw Morse code dots (.) and dashes (-) to decode them into plain text. The tool includes a Web Audio API tone generator that synthesizes real-time Morse code audio sounds (beeps). Adjust audio playback frequency (Hz) and playback speed (WPM) to practice listening and decoding Morse code signals.
