Mã Morse encode/decode

Morse code represents every letter and digit as a combination of short (dot) and long (dash) signals. This tool encodes Latin and Cyrillic text into that system and decodes it back.

How to use it

• Encode: enter text and each character turns into a sequence of dots and dashes, with spaces between letters and a slash between words.
• Decode: paste a Morse sequence to get plain text back.
• Characters with no entry in the Morse table are simply skipped, without an error.

Common uses

• A teaching example when learning the history of telegraphy or the basics of information encoding.
• Decoding a Morse message from a movie, game, or puzzle.
• Composing a Morse message for a ham radio hobby or a signaling exercise.

Things to keep in mind

Standard Morse timing: a dash is three times as long as a dot, the gap between letters equals three dots, and the gap between words equals seven.

SOS (···---···) is traditionally sent with no gaps between its letters — it's a fixed distress signal, not the result of applying the ordinary encoding rules.
