English to Morse Code – Accurate ITU Converter, Free

International morse, not “American” morse

Two morse variants exist. Original American Morse (or “Railroad” morse) used variable-length internal spaces and survived in US railroad telegraphy into the 1970s. Almost nothing uses it today. International Morse — standardised in 1865 at the International Telegraph Conference in Paris — uses only short and long pulses with fixed gaps, and is the one we convert to.

Every letter A–Z, digit 0–9, and the full punctuation set (period, comma, question mark, exclamation mark, apostrophe, quotation mark, parentheses, colon, semicolon, hyphen, ampersand, at-sign, dollar-sign, plus-sign, equals-sign, forward-slash, and underscore) is in our table.

How the converter handles edge cases

Mixed case: morse has no uppercase-vs-lowercase distinction. The converter normalizes everything to uppercase before encoding.
Numbers: each digit is a fixed five-element code (e.g. 3 = ...--). Great rhythm for drilling at speed.
Punctuation: commas and periods are common and well-supported. More exotic marks (emoji, CJK, diacritics) aren't in ITU morse and get silently dropped rather than producing a?.
Spaces and paragraphs: single spaces become the word separator /. Multiple consecutive spaces and line breaks collapse to a single / — morse has no concept of a paragraph break.

Common conversions

HELLO → .... . .-.. .-.. ---
73 (ham radio for “best regards”) → --... ...--
CQ (calling any station) → -.-. --.-
I LOVE YOU → .. / .-.. --- ...- . / -.-- --- ..-

Frequently asked questions

How do you write English in morse code?

Each letter of the English alphabet has a unique pattern of dots and dashes in the international morse table. Type English into the box above — the converter returns the morse pattern with proper letter gaps (one space) and word gaps (forward slash).

Why does my morse look different from what I saw elsewhere?

You may be seeing 'American morse' from old railroad references. International morse (what this page uses) is the modern standard — every post-1865 textbook, ham radio manual, and Boy Scouts merit badge uses it.

Is the converter accurate for radio contesting?

Yes. The underlying lib/morse.ts table is the full ITU alphabet unit-tested against every character. The timing presets (5–40 WPM) match standard CW operator practice; Farnsworth spacing is available for learners.
