About This Tool & Technical Logic
International Morse code encodes each letter, digit, and some punctuation as a sequence of dots (·) and dashes (−). Letters are separated by spaces, words by a slash or three-space gap. Timing convention: a dash equals three dots, with one-dot gaps between elements.
The encoder supports A–Z, 0–9, and common punctuation. The decoder tolerates both "."/"-" and "·"/"−" symbols and infers word boundaries from slashes or multiple spaces — so morse copied from any source decodes cleanly.
Lookup table ITU Morse: A=·− … Z=−−··, letters joined by ' ', words by ' / '.
How to Use — Step by Step
- 1
Choose direction
Encoding produces a copyable morse string; decoding reconstructs the original message from pasted morse.
- 2
Mind word separators
When encoding, words come out separated by " / " — keep those slashes when round-tripping.
- 3
Try reading it aloud
"SOS" encodes to three dots, three dashes, three dots — the famous pattern chosen because it's unmistakable at any speed.

Rarely commercially, but amateur radio operators use it daily (it's a licensed skill), and its simplicity keeps it relevant for emergency signalling with light or sound.
