Korean Romanization Converter

It is the official system for writing Korean in Latin letters in South Korea, introduced by the Ministry of Culture and Tourism in 2000. It uses only basic Latin letters with no apostrophes or accents (eo and eu instead of ŏ and ŭ) and is used for road signs, place names, textbooks and, by convention, most passport names.

Revised Romanization follows pronunciation, not spelling. In 독립문, ㄹ after ㄱ becomes ㄴ, which then turns ㄱ into ㅇ (nasalization), and ㅂ before ㅁ becomes ㅁ. Koreans actually say [동님문], so it is written Dongnimmun. The letter-by-letter line shows the spelling-based version for comparison.

Liaison of a final consonant into a following vowel (먹어 meogeo), the seven final sounds, nasalization (감사합니다 gamsahamnida), ㄹ to ㄴ after ㅁ, ㅇ, ㄱ and ㅂ (종로 Jongno), ㄹ assimilation (신라 Silla, 설날 Seollal), aspiration with ㅎ (좋다 jota), palatalization (같이 gachi) and silent ㅎ before vowels (좋아 joa). Tensification, such as 학교 sounding like hakkyo, is not written in Revised Romanization, as the official rules specify.

By official rules, the family name comes first, separated by a space, and sound changes between the syllables of the given name are not transcribed, for example 한복남 Han Boknam. Tick Personal names to turn sound changes off. Many people keep a traditional spelling of their family name, such as Lee for 이, Park for 박 and Kim for 김, so always use a person's own preferred spelling.

McCune–Reischauer (1937) marks vowels with breves (ŏ, ŭ), writes aspirated consonants with an apostrophe (k', t', p', ch') and writes ㄱ, ㄷ, ㅂ and ㅈ as k, t, p and ch at the start of a word and g, d, b and j between voiced sounds, so 부산 is Pusan. It was the standard in South Korea until 2000 and a version is still used in North Korea and in many older books.

Revised Romanization allows a hyphen where a syllable boundary could be misread, for example 중앙 jung-ang (not jun-gang) and 반구대 Ban-gudae. The default setting adds hyphens only in those ambiguous spots; you can also remove them or put one between every syllable for learners.

Yes, as a spelling helper. The Roman letters → Hangul tab splits Revised Romanization into syllables and writes them in Hangul as they sound. Because sound changes cannot be undone automatically, gamsahamnida becomes 감사함니다 rather than the correct spelling 감사합니다, so use it as a starting point.
