What is Morse Code?

Morse code is a method of encoding text characters as sequences of two different signal durations — called dots (·) and dashes (−). It was developed in the 1830s by Samuel Morse and Alfred Vail for use with the electric telegraph. Each letter, digit, and punctuation mark has a unique combination of dots and dashes. Despite being over 180 years old, Morse code is still used today in aviation, amateur radio, and emergency signaling.

How to Use the Morse Code Converter

1. Text → Morse: Type or paste any text and click Convert to Morse. The output shows the encoded Morse string, a visual dot-dash pattern, and audio/flash controls.
2. Morse → Text: Switch to Morse → Text mode. Enter Morse code using . for dots and - for dashes. Separate letters with a single space and words with / or a double space.
3. Use Play Audio to hear the Morse code using the Web Audio API beep tones.
4. Use Flash Light to see the Morse code as a visual light signal — useful for learning.
5. Adjust speed in WPM (words per minute) using the slider (5–40 WPM).

Key Features

• Visual flash: Animated light bulb that flashes the Morse signal in real time.
• Visual strip: Dot-dash pattern rendered as graphical shapes below the output.
• Adjustable speed: 5 to 40 WPM slider for audio and flash playback.
• Full reference chart: Complete International Morse Code table for letters, digits, and punctuation — filterable and clickable.
• 100% browser-based: No server calls, no data uploads.

Morse Code Format Guide

• A dot (.) is a short signal.
• A dash (-) is a long signal (3× the length of a dot).
• Letters are separated by a single space.
• Words are separated by a slash (/) or a double space.
• The most famous Morse code sequence is SOS: ... --- ...

Common Uses of Morse Code Today

• Amateur (Ham) Radio: Morse code proficiency was required for amateur radio licensing for decades and is still widely practiced.
• Aviation: VOR navigation beacons and NDB beacons still transmit station identifiers in Morse code.
• Emergency Signaling: SOS can be sent using a flashlight, mirror, sound, or radio in survival situations.
• Assistive Technology: People with motor disabilities can use Morse code input as an accessibility tool.
• Education & Puzzles: Morse code is popular in escape rooms, cryptography courses, and STEM education.
