Morse Code Decoder & Encoder
beginnerEncodes letters as sequences of dots and dashes
What is Morse Code?
Morse code is a method of encoding text characters as sequences of two signal durations, called dots (·) and dashes (−). Developed by Samuel Morse and Alfred Vail in the 1830s-40s, it was the first widely-used data encoding for long-distance communication over telegraph wires.
How Morse Code Works
Each letter, digit, and punctuation mark has a unique sequence of dots and dashes. A dot is a short signal; a dash is three times longer. Letters are separated by a short pause, words by a longer pause (represented here as /).
Morse Code in Pop Culture
Morse code appears in countless movies, TV shows, and video games. The "SOS" distress signal (... --- ...) is perhaps the most recognized sequence. Movies like "Contact," "The Imitation Game," and many war films feature Morse. It's used in escape rooms and geocaching.
How to Break Morse Code
Morse code is an encoding, not encryption — anyone with a Morse chart can decode it instantly. It provides no security. Our decoder handles this automatically.

How do I decode Morse Code?
Enter your ciphertext in the tool above, select "Morse Code" from the dropdown, choose Decode mode, and click the button. Results appear instantly.
What is Morse Code used for?
Morse Code was used since 1837 for secret communication. While not secure by modern standards, it's widely used in puzzles, escape rooms, and educational contexts.
How secure is Morse Code?
Morse Code is not secure by modern standards — it can be broken quickly with basic cryptanalysis or brute force. Use it for puzzles and learning, not sensitive data.
Who invented Morse Code?
Morse Code was invented by Samuel Morse around 1837.
