What is Greek Morse code?

It is the set of dot-dash sequences traditionally used to send the 24 letters of the Greek alphabet by telegraph. Many codes are borrowed from the Latin letter that matches the Greek letter's sound.

How are accented vowels handled?

Accented vowels such as ά, έ, ή, ί, ό, ύ and ώ are normalised to their unaccented base letter before encoding, since Morse has no accent marks.

What about final sigma?

The word-final form ς is treated the same as the regular sigma Σ and encodes to three dots, because Morse does not distinguish letter position.

How are words separated?

Letters within a word are separated by a single space and words by three spaces. When decoding you can also use a forward slash to mark word boundaries.

Is my text uploaded anywhere?

No. The conversion runs entirely in your browser using a built-in lookup table, so nothing is sent to a server.

Greek Morse Code Encoder

Greek Morse code assigns a dot-dash sequence to each of the 24 letters of the Greek alphabet. Because Greek and Latin share many sounds, several Greek letters reuse the Morse code of their Latin equivalent — for instance, alpha takes alef-style .- and tau takes -. This free tool encodes Greek text into Morse and decodes it back, instantly in your browser.

How it works

Encoding first normalises each character: accented vowels lose their accent and the final sigma ς becomes the regular sigma Σ. Each normalised letter is then looked up in a fixed table and replaced with its code. Letters within a word join with single spaces and words separate with three spaces. Digits and basic punctuation use the standard international Morse codes.

Decoding reverses the table: each space-separated code becomes its Greek letter, and three-space (or slash) gaps become word breaks. Tokens with no known mapping pass through unchanged.

Example and notes

The word ΓΕΙΑ (hi) encodes letter by letter as:

--. . .. .-

Distinctly Greek codes include theta -.-., xi -..-, psi --.-, and omega .--. Note that several Greek and Latin letters that look alike can map to different codes, so always use the Greek table for Greek text. Everything runs offline, so your text never leaves the page.
