How to Use Morse Code
Enter Your Text
Type or paste text into the input panel. You can enter regular text to convert to Morse code, or Morse code (dots and dashes) to convert back to text.
Choose Direction
Click "Text to Morse" to encode text as Morse code signals, or "Morse to Text" to decode dots and dashes back into readable characters.
Copy and Use
The result appears on the right. Morse output uses "." for dots and "-" for dashes, with spaces between characters and "/" between words.

... --- ...Frequently Asked Questions
What is Morse code?
Morse code is a method of encoding text as sequences of short and long signals (dots and dashes). Developed in the 1830s for telegraph communication, it was the first practical method of electronic text transmission. Each letter and digit has a unique dot-dash pattern, with more common letters (like E = ".") getting shorter codes.
How are letters separated in Morse code?
In this converter, individual characters are separated by a single space, and words are separated by " / " (space-slash-space). When transmitted by sound or light, a dot is one unit, a dash is three units, the space between dots/dashes is one unit, between letters is three units, and between words is seven units.
Does Morse code support numbers and punctuation?
Yes, this converter handles A-Z, 0-9, and common punctuation marks (. , ? / ! @ &). Characters that don't have a standard Morse representation are left as-is in the output. Lowercase letters are automatically converted to uppercase, as Morse code is case-insensitive.
Why Morse Code Endures
Morse code is nearly 200 years old, yet it remains in use today. Amateur radio operators use it worldwide, it\'s built into aviation navigation aids (VORs transmit their identifier in Morse), and it\'s used in assistive technology for people with limited mobility. The simplest possible encoding — just two states, on and off — makes it uniquely robust across any transmission medium.
Famous Morse Signals
- ··· --- ··· (SOS) — International distress signal. Not actually an acronym; chosen for its simple, unmistakable pattern.
- ··· — · — (CQ) — General call to any station. "Seek you."
- — · · · — (SK) — End of contact. Used to sign off.
- · — · — · (AR) — End of message. "Out."
