What this tool does
This Korean romanizer transliterates Hangul sentences and words using the Revised Romanization of Korean. When you want to read signs, menus, place names, or words in roman letters, it converts syllable by syllable while preserving spaces and punctuation. Great for Korean learners and for adding roman spellings to Korean content. (For a passport name, use the dedicated 'Korean Name Romanizer' instead.)

Spelling basis
Based on the Revised Romanization of Korean (2000), each syllable is decomposed into initial, medial, and final jamo and transliterated. Vowels: ㅏ=a, ㅓ=eo, ㅗ=o, ㅜ=u, ㅡ=eu, ㅣ=i, ㅐ=ae, ㅔ=e ... Consonants: ㄱ=g/k, ㄷ=d/t, ㅂ=b/p, ㅈ=j, ㅊ=ch, ㄹ=r/l ... Note: this is syllable-by-syllable transliteration that does NOT apply sound changes (assimilation). e.g. 신라 → Sinra (not the spoken Silla) e.g. 종로 → Jongro (not the spoken Jongno) Official spellings reflect pronunciation changes, so treat results as a reference.
Worked examples
Example 1: 안녕하세요 → Annyeonghaseyo
Syllables 안=an, 녕=nyeong, 하=ha, 세=se, 요=yo → Annyeonghaseyo. The most basic greeting, romanized.
Example 2: 서울 시청 → Seoul Sicheong
The space is preserved into two words, each capitalized. Ideal for reading place and institution names.
Example 3: 김밥 → Gimbap
Romanizes the menu item gimbap as Gimbap — for explaining a menu to foreign guests.
Frequently asked questions
Does it apply sound changes (assimilation)?+
No. This is syllable-by-syllable transliteration, so phonological changes like consonant assimilation are not reflected — e.g. 신라 → Sinra (actually pronounced Silla). For accurate pronunciation spelling, check the official romanization.
Can I use this for my passport name?+
Not recommended. Passport names should follow the official guidance and existing family spelling conventions, so use the dedicated 'Korean Name Romanizer' or the official guidance instead.
Why does ㅓ become 'eo' and ㅡ become 'eu'?+
The Revised Romanization defines ㅓ=eo and ㅡ=eu. These two-letter combinations represent Korean vowels that have no single English-letter equivalent.
Are final consonants (batchim) converted?+
Yes, final consonants are romanized as the syllable's final jamo. However, the real pronunciation where a batchim links or assimilates with the next syllable is not reflected (syllable-level processing).
What about mixed English and numbers?+
Non-Hangul characters (English, numbers, symbols, spaces) are preserved as-is. Only Hangul syllables are transliterated into roman letters.
