About Morse Code Encoder
International Morse Code represents letters and digits as sequences of short signals (dots, .) and long signals (dashes, -). This tool encodes ASCII letters, digits, and common punctuation. Words are separated by ' / ' to make decoding unambiguous.
When to use it
- Producing Morse for amateur radio practice
- Generating puzzle content for escape rooms or CTFs
- Teaching about historical telegraph encoding
- Recoding text for use in flashing-light or sound projects
How it works
Letters and digits are converted via a lookup table that follows the International Telecommunication Union (ITU) standard. Letters within a word are separated by single spaces; words by ' / '. Unsupported characters are dropped.
Examples
Hello World
.... . .-.. .-.. --- / .-- --- .-. .-.. -..
Frequently asked questions
- What's the word separator?
- A forward slash with spaces around it (' / '). This is the most common convention in printed Morse code.
- Which letters and symbols are supported?
- A–Z, 0–9, and these punctuation marks: . , ? ' ! / ( ) & : ; = + - _ " $ @. Anything else is dropped.
- Is case preserved?
- No — Morse has no case. The input is uppercased internally; case is lost on decode.
