Names into Roman letters

Enter a Korean name and it produces a romanization. Surnames use common passport spellings (김 Kim, 이 Lee, 박 Park), while given names follow the official Revised Romanization, syllable by syllable. You can also hyphenate the given-name syllables (e.g. Gil-dong).

Why surnames differ from the standard

By the book, 김 is Gim, 이 is I, and 박 is Bak — but passports and the press have long used Kim, Lee, and Park. For surnames with an established convention, the tool shows the common spelling, and where it differs it also shows the by-the-book form.

Limits and notes

  • Given-name romanization is a syllable-by-syllable approximation that does not reflect sound changes across syllables — which the standard also recommends for personal names.
  • Passport spelling is a personal choice, and matching your family or existing documents comes first. Treat this as a reference.
