Text Enter text, then click → Morse or press Ctrl+Enter (⌘+Enter on Mac). Typing alone does not convert. Letters are case-insensitive; A–Z, É, digits and the listed punctuation have codes. Other characters are skipped and listed in the status row.

Morse Code Edit this box, then click ← Text. Use . or · for dots and - or − for dashes, spaces between letters and / or | between words. Line breaks are kept. Unknown groups become [?] and are listed in the status row. Decoded letters are uppercase. Copy copies the current Morse Code box, including edits. Conversion writes · and − with one space between letters and / between words. This tool does not play audio.

Morse Code Format

Each letter is represented as a sequence of dots (·) and dashes (−) separated by spaces. Words are delimited by / . Example: ···· · ·−·· ·−·· −−− / ·−− −−− ·−· ·−·· −·· decodes to HELLO WORLD.

What Is Morse Code?

Morse code is a character encoding system developed in the 1830s for electrical telegraph communication. It represents letters and numbers as sequences of short (dot) and long (dash) signals. It is still used today in amateur radio (CW mode) and as an accessibility input method.

Timing and Format

In ITU-R M.1677-1 a dash is three dots long; the gap inside a letter is one dot, between letters three dots, and between words seven dots. In text, the tool writes the dot as · (U+00B7) and the dash as − (U+2212), separates letters with one space and words with / .

The decoder accepts ASCII . and - as well as · and −, so .... . .-.. .-.. --- / .-- --- .-. .-.. -.. gives HELLO WORLD. It also reads •, _, en / em dashes and full-width ． －, and they can be mixed in one input.
A code the table does not contain decodes to [?], and the tool lists those codes in the status row. For example the ITU error signal (eight dots) gives [?]. The brackets keep it apart from ?, which is the decoded question mark ··−−··.
É is the ITU accented e: Café 9:30, ok? becomes −·−· ·− ··−· ··−·· / −−−−· −−−··· ···−− −−−−− −−··−− / −−− −·− ··−−··. Characters without a code (other accented letters, CJK, emoji) are left out and listed in the status row: Grüße ok becomes −−· ·−· · / −−− −·− with Ü and ß listed. The tool does not expand ß to SS.
Letters are case-insensitive; decoding always returns capitals.
Prosigns such as AR or SK are sent without a letter gap. The tool has no prosign input and encodes AR as two letters.

Example: a CQ call in amateur radio, CQ DE N0CALL K, encodes to −·−· −−·− / −·· · / −· −−−−− −·−· ·− ·−·· ·−·· / −·−.

History

Samuel Morse and Alfred Vail developed the code for the electric telegraph; the first long-distance message on the Washington–Baltimore line, “What hath God wrought”, was sent on 24 May 1844. The international code in use today differs from the original American Morse in several letters. Morse is still used by amateur radio operators (CW).

FAQ

What characters are supported?

Letters A–Z, digits 0–9 and 18 punctuation marks. 13 of the punctuation codes come from ITU-R M.1677-1; ! & ; _ $ are common amateur codes that the ITU recommendation does not list. É (the accented e, ··−··) is also in the recommendation. Other characters are left out, and the tool lists them in the status row.

How are words separated in Morse code output?

Words are separated by a forward slash (/) surrounded by spaces. Each letter's code is separated by a single space.

Can I decode Morse code that uses dots and dashes?

Yes. Dots can be typed as . or ·, dashes as - or − (also •, _, en and em dashes, and full-width forms). Separate letters with spaces and words with / or |; line breaks are kept. A code that is not in the table shows as [?] and is listed in the status row.

Is audio playback supported?

No. This tool handles text-based encoding and decoding only. For audio output, a dedicated Morse code audio generator is needed.

Is my data sent to a server?
