Korean name → passport romanization

Enter values, then press Calculate.

How to use

  1. Enter the name to convert in Korean name. Example: 김민수, or 김 민수 with a space between family and given name.
  2. To look like a passport, leave Uppercase output (passport style) on. If you turn it off, only the first letter of each word is capitalized.
  3. Click Convert and check the romanized result. A hint notes that this is an approximation of Revised Romanization.
  4. Use Copy to take the result, or Reset to start over.
  5. The English on a real passport or airline ticket can differ from the Ministry of Foreign Affairs or a previous passport, so always compare before you apply.

Key concepts

Korean name romanization is one of the most searched tasks when making a passport English name, airline ticket, visa, or English business card. This tool splits Unicode Hangul syllables into initial, medial, and final, then concatenates a mapping close to Revised Romanization (for example ㄱ→g, ㅓ→eo, final ㅇ→ng). Tense consonants ㄲ, ㄸ, ㅃ, ㅆ, ㅉ become kk, tt, pp, ss, jj. If the spelling on a passport, ticket, and visa form do not match, boarding or immigration can be blocked, so matching an already issued passport is the safest rule.

Syllables are simply joined, so without a space 김민수 becomes GIMMINSU. A space between family and given name is kept. Latin letters, digits, and hyphens are not converted. This is for reference and may differ from a real passport spelling; follow a registered romanization and Ministry of Foreign Affairs rules first. Conversion runs only in the browser and is not sent to a server. Initial ㄹ is r, medial ㅓ is eo, and final ㄱ is k, so assimilation (국물→gungmul and similar) is not applied. Fix conventional spellings such as Lee or Park yourself.

Example

Enter 김민수, leave passport-style uppercase on, and convert: the romanization is GIMMINSU. With a space between 김 and 민수 it splits as GIM MINSU. Turn uppercase off and you get Gim Minsu, with only word starts capitalized. Surnames that use conventional passport spellings such as Lee or Park may differ from this result. 박지민 without a space becomes BAKJIMIN; 박 지민 becomes BAK JIMIN. With passport-style uppercase off it looks like Bak Jimin.

Frequently asked questions

Is Korean name romanization an exact passport spelling?

No. It is an approximation of Revised Romanization. Always check with the Ministry of Foreign Affairs, the passport application, and any existing English name. If even one letter differs from an existing passport or booking, follow the airline or embassy.

Do you space the family name and given name in a passport English name?

Spaces you type are kept. Often the family name stands alone and the given name is written as one word. Ministry of Foreign Affairs romanization practice mixes joining or spacing after the family name, so look at the application examples.

How are tense consonants ㄲㄸㅃㅆㅉ romanized?

They map to kk, tt, pp, ss, jj. Example: 빠→PPA (with the uppercase option). ㅉ is jj and ㅒ is yae. Read the result once more when you enter a name with tense consonants.

Is Korean romanization data sent to a server?

No. Conversion runs only in the browser and is not stored. There is no conversion log, so on a shared PC the input disappears when you close the page.

Are names mixed with Latin letters or digits romanized too?

Latin letters, digits, and hyphens stay as-is; only Hangul syllables are converted. Hyphenated double surnames keep the hyphen and only Hangul changes.

Do conventional romanizations like Lee or Park appear for 이 and 박?

Only jamo rules are applied, so you may get Yi or Bak. Fix conventional passport spellings yourself. Copy the result and change only the family name by hand.
