About Morse Code Translation
Morse code is an encoding system invented in the 19th century that represents letters, digits and punctuation with two symbols: dot (.) and dash (-). This tool converts both ways between text and Morse: encoding turns text into a dot-dash sequence (spaces between characters, "/" between words); decoding restores the sequence to the original text. It supports all 26 English letters, digits 0-9 and common punctuation, with a full reference chart below. For hex/binary encoding conversion, use the Text Encoding Converter.
Use Cases
Morse code is widely used in radio communication, maritime and aviation signals, and military message transmission. Amateur radio operators use it over CW mode for long-distance contacts; films and literature often use Morse to build suspense; escape rooms and puzzle games commonly feature it; and the SOS distress call (... --- ...) is an internationally recognized emergency signal. This tool also helps beginners practice encoding and decoding with the full chart below.
FAQ
What do "." and "-" mean in Morse code?
A dot (.) is a short signal (dit) lasting 1 unit; a dash (-) is a long signal (dah) lasting 3 units. Letters combine dots and dashes — "A" is ".-" (dit-dah), "S" is "..." (dit-dit-dit). Characters are separated by 1 unit and words by 3 units (commonly written "/").
Is Morse code case-sensitive?
No. Morse code is not case-sensitive; all letters use the same sequence. This tool uppercases the text before encoding and outputs uppercase letters. If you need to preserve the original case, adjust it after decoding.
Can Morse code be used to encrypt messages?
Morse is not an encryption algorithm but a character-encoding method — anyone with the chart can decode it easily. For real encryption, use Base64 or algorithms such as AES/DES. Morse is better suited to signal transmission, puzzle games or amateur radio learning.
What is the Morse code for the SOS distress signal?
SOS is "... --- ..." in Morse (three short, three long, three short), the internationally recognized emergency signal. It was originally chosen by German radio regulations because it is simple to remember and easy to key and recognize. Note that it is not an abbreviation of the letters "SOS" but is sent as a continuous sequence.
Does encoding/decoding here leak my data?
No. All encoding and decoding runs locally in your browser; input and output are never uploaded to any server. The tool works fully offline, keeping your data safe.
