Korean Romanization
Convert Hangul to Revised Romanization with common sound changes, or select spelling-based strict transliteration.
Korean Romanization: Revised Romanization combines syllable spelling with pronunciation changes: liaison, nasal and liquid assimilation, palatalisation and aspiration. Strict transliteration preserves written letters and uses hyphens to distinguish silent onsets and certain adjacent letters. Runs 100% locally in your browser with zero server file uploads.

Revised Romanization includes liaison, nasal and liquid assimilation, palatalisation and aspiration. Some changes depend on word boundaries and meaning; epenthesis and noun exceptions include the official examples. Review personal names, compound words and administrative suffixes separately.
Official rules
National Institute of Korean Language, Romanization of Korean, Ministry of Culture rules of 2000: https://www.korean.go.kr/front_eng/roman/roman_01.do . The pronunciation rules and special transliteration provision are described there.
Scope of automatic conversion
Korean spelling alone cannot always reveal morpheme boundaries or part of speech. The converter includes the official epenthesis examples and noun aspiration exceptions; review unfamiliar compounds.
Unicode Hangul syllables: https://www.unicode.org/charts/PDF/UAC00.pdf . Canonically decomposed Hangul is normalised before conversion.

Frequently asked questions
Does it include sound changes?
Yes. It includes the National Institute of Korean Language examples for liquid and nasal assimilation, liaison, palatalisation and aspiration. Changes that depend on word meaning or morpheme boundaries can need review.
What does strict mode do?
It follows the spelling provision in section 3(8). Written consonants remain distinct, while hyphens mark internal silent onsets and ambiguous letter joins. It is intended for spelling comparison rather than pronunciation.
Can I use this for personal names?
Review names separately. Revised Romanization treats sound changes within given names differently, permits established spellings and has additional rules for administrative suffixes. Capitalise each word can format place-name examples but does not decide whether a word is a proper name.
